The process $p+p\to W^\pm W^+ W^-$ with lepton decays of $W$-bosons is shown to be promising for improving conditions for studies of parameter $\lambda$, which is the anomalous triple $W$-bosons interaction coupling constant., Comment: 8 pages, 2 figures

A possible effective interaction in the quantum gravity is considered. The compensation equation for a spontaneous generation of this interaction is shown to have a non-trivial solution. Would be consequences of a possible existence of effective interactions in the gravity theory are discussed. An example of running gravitational coupling is presented, which corresponds to a description of effects, which nowadays are prescribed to a dark mater and to a dark energy., Comment: 14 pages, 9 figures

Recently reported diboson excesses at LHC are interpreted to be connected with heavy $WW$ resonance with weak isotopic spin 2. The resonance appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant $\lambda$. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in inclusive production of $W^+W^+, W^+ (Z,\gamma), W^+ W^-, (Z,\gamma) (Z,\gamma), W^- (Z,\gamma), W^-W^-$ resonances with $M_R \simeq 2\,TeV$, which could be reliably checked at the upgraded LHC with $\sqrt{s}\,=\,13 TeV$. In the framework of an approach to the spontaneous generation of of the triple anomalous interaction its coupling constant is estimated to be $\lambda = -\,0.017\pm 0.005$ in an agreement with existing restrictions., Comment: 5 pages, 1 figure

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)., LaTeX, 18 pages, 2 figures, to be published in Mod.

Under assumption of singular behavior of 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 matching the beta-function at a boundary of perturbative and non-perturbative regions. The contribution of the non-perturbative region to the gluon condensate is calculated with varying normalization condition alpha_s(m_tau^2) = 0.29, 0.30,..., 0.36 for two different ways of definition of the non-perturbative invariant charge in the infrared region. We obtain quite consistent results for values of the gluon condensate, nonperturbative region scale q_0, and the string tension sigma., Comment: LaTeX, 10 pages, 2 figures, added reference, not great elucidation after eq.(3) and in abstract

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

The problem of possible deviations from the Standard Model is considered in the framework of a variant of dynamical electroweak symmetry breaking. The parameters of the theory are obtained, which describe deviations from SM in $Z\to \bar b b$ decay, are also consistent with leptonic left-right asymertry (SLAC data) and 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 $t\to c$. The intensity of this transition is connected with the $c$-quark mass, that leads to estimates of probabilities of exotic decays $t\to c (Z,\gamma)$ (few %) and of the cross-section of a single $t$-quark production in process $e^+e^-\to t \bar c$ at LEP2 ($\simeq 0.03 pb$ at $\sqrt{s} = 190 GeV$). The model is shown to be consistent with the totality of the existing data; the predictions allow its unambiguous check., Comment: 9 pages, Latex.

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
