Using the approach based on Bogoliubov compensation principle is applied to calculation of a contribution to the muon $g-2$. Using the previous results on spontaneous generation of the effective anomalous three-boson interaction we calculate the contribution, which proves to agree with the well-known discrepancy. The calculated quantity contains no adjusting parameters but the experimental values for the muon and the W-boson masses. The result can be considered as a confirmation of the approach., Comment: 9 pages. 2 figures used. arXiv admin note: substantial text overlap with arXiv:1304.7090

We are considering a possibility for detecting non-perturbative effect in process of top pair production in association with a high $p_T$ photon. Starting from previous results on two solutions for a spontaneous generation of wouldbe effective interaction of a top pair with a pair of electro-weak bosons, we show, that a solution with effective cut-off $\Lambda \simeq 10^2\,TeV$ is already contradicting to existing data, while the other one with $\Lambda \simeq 10^{16}\,TeV$ (just the Planck scale) could be reconciled with data and give predictions for process $p+p\to\bar t t \gamma+X$, which could be effectively checked at the LHC with $\sqrt{s}=13\,TeV$. The confirmation of the predictions would mean a strong support for the existence of non-perturbative effects in the electro-weak interaction., Comment: 5 pages, 2 figures, corrections made, typos corrected

Assuming an existence of an anomalous triple electro-weak bosons interaction being defined by coupling constant $\lambda$, we calculate its contribution to interactions of the Higgs with pairs of heavy particles. Bearing in mind experimental restrictions $-0.011 < \lambda < 0.011$ we present results for possible effects in processes $p\,p \to W^+ W^- H,\,p\,p \to W^+ Z H,\,p\,p \to W^- Z H,\,p\,p \to \bar t t H $, $p p \to \bar b b H$. Effects could be significant with negative sign of $\lambda$ in associated heavy quarks $t,\,b$ pairs production with the Higgs. In calculations we rely on results of the non-perturbative approach to a spontaneous generation of effective interactions, which defines the form-factor of the three-boson anomalous interaction., Comment: 6 pages, 2 figures, few typos corrected, references added

Recently reported diboson and diphoton excesses at LHC are interpreted to be connected with heavy $WW$ zero spin resonances. The resonances appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant $\lambda$. The $2\, TeV$ anomaly tentatively corresponds to weak isotopic spin 2 scalar state and the $\gamma\gamma\,\,750\, GeV$ anomaly corresponds to weak isotopic spin 0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in a production of $W^+ W^-, (Z,\gamma) (Z,\gamma)$ via resonance $X_{PS}$ with $M_{PS} \simeq 750\,GeV$, which could be reliably checked at the upgraded LHC at $\sqrt{s}\,=\,13\, TeV$. In the framework of an approach to the spontaneous generation of the triple anomalous interaction its coupling constant is estimated to be $\lambda = -\,0.02\pm 0.005$ in an agreement with existing restrictions.

We describe application of Bogoliubov compensation principle to calculation of non-perturbative contribution in the electroweak theory and QCD. We obtain unique solutions of compensation equations, which impose strong restrictions on parameters of theories and on functional dependence of corresponding form-factors. We calculate value of running gauge electroweak coupling $\alpha_w(M_W)=0.0374$, that differs from the experimental value less than by 10%. We derive effective Nambu-Jona-Lasinio interaction from fundamental QCD and express its parameters in terms of initial QCD parameters: $\alpha_s$ at low-momenta and current mass of light quarks. This leads to satisfactory description of low-mass hadron physics., Comment: 6 pages, no figures, talk presented at the International Bogolyubov Conference, August 21-27, 2009, Moscow-Dubna, Russia

Under assumption of singular behavior of invariant charge alpha_s(q^2) at q^2 sim 0 and of large q^2 behavior, corresponding to the perturbation theory up to four loops, a procedure is considered of smooth matching the beta-function at a boundary of perturbative and nonperturbative regions. The procedure results in a model for alpha_s for all q^2>0 with dimensionless parameters being fixed and dimensional parameters being expressed in terms of only one quantity Lambda_QCD. The gluon condensate which is defined by the nonperturbative part of the invariant charge is calculated for two variants of ``true perturbative'' invariant charge, corresponding to freezing option and to analytic one in nonperturbative region. Dimensional parameters are fixed by varying normalization condition alpha_s(m^2_tau) = 0.29, 0.30, ..., 0.36. It is obtained that on the boundary of perturbative region alpha_0 = alpha_s(q_0^2) simeq 0.44, the procedure results in nonperturbative Coulomb component alpha_Coulomb simeq 0.25, the nonperturbative region scale q_0 simeq 1 GeV, the model parameter sigma simeq (0.42 GeV)^2 which suits as string tension parameter, the gluon condensate appears to be close for two variants considered, K simeq (0.33 -- 0.36 GeV)^4 (for alpha_s(m^2_tau) = 0.33)., Comment: LaTeX, 18 pages, 2 figures, to be published in Mod.

Theory with $SU(2)\times U(1)$ gauge invariant electroweak Lagrangian describing standard interaction of massless quark doublet without elementary scalar Higgs sector is considered. We show in the main order of $1/N_c$ expansion, that there exists a solution, which breaks initial symmetry and is accompanied by an appearance of zero mass composite scalar doublet. The electroweak loop corrections shift its mass to a tachyon value and thus the scalar serves as a substitute for usual elementary Higgs. The $t$-quark mass also arise. The problem of adjusting its observable mass leads to prediction of triple gauge constant $\lambda_V \simeq -0.034$ without contradiction with experimental data. The mass of the surviving composite Higgs scalar is predicted to be $M_H = 117 \pm 7 GeV$, that agrees with recent indications of $M_H \simeq 115 GeV$. The resulting theory contains realistic $W, Z, t$ masses, composite massive Higgs and massless other particles. Parameters used are cut-off $\Lambda \simeq 3500 GeV$, weak gauge constant $g$ and mixing angle $\theta_W$., Comment: 16 pages, latex, 6 figures, 1 table

A model of interaction of massless vector and spinor fields is considered. With the use of Bogolyubov quasi-average method we study a possibility of a dynamical breaking of the initial symmetry. Assuming the existence of effective cut-off $\Lambda$, we show, that there exists a solution, which breaks gauge symmetry of the theory. Instead of Higgs scalars fermion-antifermion tachion bound states are present here.

The problem of possible deviations from the Standard Model is considered in the framework of a variant of dynamical electroweak symmetry breaking. It comes clear, that the parameters of the theory, being obtained earlier and describing deviations from SM in Z --> \bar b b decay, are also consistent with the existence of a nontrivial solution for vertex \bar t (Z,\gamma) c. The occurrence of this solution leads to a significant enhancement in neutral flavor changing transition t --> c. The intensity of this transition is connected with the c-quark mass, that leads to estimates of probabilities of exotic decays t --> c (Z,\gamma) (few %) and of the cross-section of a single t-quark production in process e^+e^- --> t \bar c at LEP2 (around 0.03 pb at \sqrt{s} = 190 GeV).

The H1 and ZEUS anomalous events are interpreted as being due to the production and the decay of excited leptons $E$, which correspond to spin 1/2 resonances of the first generation lepton doublet ($\nu_e, e$) with W triplet. This assumption is supported by considering of Bethe-Salpeter equation in the ladder approximation with anomalous triple gauge boson vertex. The solution with weak isospin $I = 3/2$ is shown to exist for zero mass state, that means M_E$ is small in comparison with TeV mass scale. The coupling of $E$ with leptons and $W$ is defined by the normalization condition. Calculation of the $E$ width and the production cross-sections agrees with HERA data for value of the triple $W$ coupling constant $\lambda \simeq 0.5$. Isotopic relations for different channels are presented as a tool for checking the interpretation., Comment: 8 pages, latex, no figures

Triple gauge boson vertex, which is inherent to the model of a dynamical breaking of the electroweak symmetry, leads to an effective four-fermion interaction of quarks. Calculation of the effective coupling constant in the framework of the model results in agreement with recent information on enhancement of inclusive high E_T jet cross section at \sqrt{s} = 1.8 TeV. Thus this effect may be connected with triple gauge boson vertex with coupling constant \lambda \approx 0.7, which will clearly manifest itself at the soon forthcoming LEP II., Comment: 4 pages, LaTeX

Dipole moments of cyclic esters of carbonic acid in benzene solution are measured and compared with theoretical calculations. Dipole moments are reported for ethylene carbonate (4-80D), 1:3 propylene carbonate (5-21D) and 1:3 butylene carbonate (5-23D). These values are shown to be consistent with theoretically calculated values for the corresponding open chain compounds dimethyl carbonate and diethyl carbonate in the appropriate stereochemical configurations.

Methyl phenylphosphinate reacts with tetracyclone in the absence of catalysts according to a scheme involving 1,4 and 1,6 addition of the conjugated cyclone system to form methyl 2,3,4,5-tetraphenyl-4-cyclopenten-1-one-3-phenylphosphinate and 2,3,4,5 -tetraphenyl-3-cyclopenten-1-one-2-phenylphosphinate, respectively. 2. Upon heating, the 1,6 adduct is prototropically isomerized to form methyl 2,3,4,5-tetraphenyl-4-cyclopenten-1-one-2-phenylphosphinate and simultaneously dissociates back to the original components, which again react to form the thermodynamically more stable 1,4 adduct. 3. The β- and γ-conjugated keto phosphinates with a cis configuration of the methylidyne proton and the phosphinate group have been isolated in the form of pairs of diastereomers with respect to the asymmetric phosphorus and carbon atoms. © 1978 Plenum Publishing Corporation.

Acyl isocyanates react with β- keto esters to give both O- and C-addition products. The O-addition products subsequently rearrange to the thermodynamically more stable C-addition products. © 1980 Plenum Publishing Corporation.

1. The conformational equilibrium in seven-membered 2-chloro(bromo)cyclohexanone ketals derived from 2-butenediol and its 2,3-dichloro and benzo analogs is ananchomerically shifted in favor of the axial form. 2. A graphical method is proposed for processing the dipole-moment data for this series of compounds. © 1981 Plenum Publishing Corporation.

Independent of the nature of the solvent, the reaction of 2-acetyl-5-methyl-1,2,3-diazaphosphole with diazoacetic ester proceeds without the evolution of nitrogen to give Δ2-phosphapyrazoline derivatives. The latter in CH2Cl2, CH3CN, or alcohols are isomerized to compounds with two NH groups. © 1984 Plenum Publishing Corporation.

1. On the basis of data on the Kerr effect in solutions, the stereoisomers of 5-phenyl-5-oxo- and 5-phenyl-5-thiono-2,4,6-trimethyl-1,3,5-dioxaphosphorinanes, differing in the position of the exocyclic substituents on the P atom, are characterized by nearly parallel orientation of the plane of the benzene ring and the plane of the bonds {Mathematical expression}. In the conformation that we have found, optimal structural conditions are realized for resonance interaction of the π-orbitals of the phenyl radical and the P=X bond. 2. This sort of interaction in the UV spectra is manifested in a bathochromic shift of the benzene absorption bands (particularly λ2) and their intensification. In the sulfides, the absorption bands of the benzene overlap those of the thiophosphoryl group. © 1982 Plenum Publishing Corporation.
