Abstract

The form factors of the semi-leptonic decays K+→π0e+ν and K+→π0μ+ν have been investigated using a sample of events detected in the CERN 1.1 m3 heavy liquid bubble chamber. Analyses have been carried out using methods independent of any assumption of the q2 dependence of the form factors in addition to the usual linear parametrizations. Consistent results have been obtained from separate studies of both Dalitz plot density distributions and the branching ratio. A parametrized global analysis of both decay modes gives the values ξ(0) = -1.3 ± 0.7 and ξ(4.4 Mπ2) = -0.45 ± 0.13, or λ0 = - 0.017 ± 0.011 both for a fitted value of λ+ = 0.025 ± 0.007. © 1975., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

Using a propane bubble chamber the average cross-section for single pion production by neutrinos on free protons has been determined to be (1.13 ± 0.28) × 10 −38 cm 2 for neutrinos of energy between 1 and 4 GeV. The invariant mass distribution of the ( π p) system indicates that N ∗ (1236) production is the dominant process. Angular distributions of the pion in the ( π p) rest frame are also presented. The results of the experiment are compared with theoretical predictions.

Abstract

Neutrino scattering cross-sections in the deep inelastic continuum have been determined and shown to exhibit the point-like behaviour, or scale invariance, previously observed in electroproduction experiments. The structure functions display the features predicted by the Pomeron exchange model for virtual W-scattering. Their magnitudes are compared with various theories.

Abstract

The partially conserved axial current hypothesis (PCAC) can be checked in the inelastic neutrino inteiactions for small values of q2, square of the leptonic transfer quadrivector. It relates the differential cross section for the reaction v, + a + p- + /3 to the cross section n+ + a + P for the same hadronic mass Mn in both reactions. This study shows that the experi- mental results are in agreement to one standard deviation with PCAC's predictions, for q2 < 0.12 GeV/c. We show especially that the correction due to the transverse component of the weak current, estimated by the vector dominance model, is important.

A study has been made of 2700 decays of the type K + → π o e + v in the CERN 1.1 m 3 heavy liquid bubble chamber. The four-momentum transfer dependence of the form factor f + ( q 2 ) has been determined. The usual linear parametrization f + ( q 2 ) = f + (0) (1+ λ + q 2 / m 2 π ) gives λ + = 0.027 ± 0.010.

A total of 15000 neutrino and antineutrino events has been examined for possible evidence of semi-leptonic decay of a charmed particle. One candidate has been observed. Upper limits on charmed particle production cross-sections are given as a function of the neutrino energy and the invariant mass of the final state hadrons.

Abstract

The search for the muonic and the nonleptonio decays of the hypothetical intermediate boson among the neutrino events produced in the CERN neutrino experiment has been continued and concluded. The data do not give any clear evidence for such decays. Comparing the rate of possible boson reactions, observed in the spark chamber and the bubble chamber, with the calculated production rate, we arrive at a lower limit for the boson mass, ranging from 1.7 to 2.2 GeV/c2 for various assumptions about the relative abundanceB of leptonic decays (Table VI).

Abstract

Events induced by neutral particles and producing only hadrons, but no muon or electron, have been observed in the heavy liquid bubble chamber Gargamelle exposed to neutrino (v) and antineutrino ( v ) beams at CERN. A study of the various sources which could give rise to such events reveals that less than 20% could be attributed to neutrons or KL°. The events behave as expected if they arise from neutral current processes induced by neutrinos and antineutrinos. The ratio of the number of these events to the number of corresponding events with charged lepton is 0.22 ± 0.04 for v and 0.43 ± 0.12 for v .

Abstract

Using a heavy-liquid bubble chamber, the ratio of the decay rates K 0 L → 2 γ /K 0 L → 3 π 0 has been determined to be (2.5 ± 0.7) × 10 −3 .
