    Abstract The coherent production of 3π systems by charged current antineutrino interactions on neon nuclei is studied in the bubble chamber BEBC exposed to the CERN SPS wide band beam. The coherent signal is attributed mainly to (ρπ) production, where the (ρπ) system is either non-resonant or comes from the decay ofa 1 mesons. The kinematical variables and the total cross section are compared with the predictions of the meson dominance model.

    Abstract TheW andQ 2 dependence of the transverse momentum of the forward-going hadrons in deep inelastic neutrino charged current interactions on neon is studied. The data were obtained by exposing BEBC filled with a Ne/H2 mixture to the CERN SPS wide-band neutrino beam. The data on average transverse momentum are compared to a model which includes first order QCD, intrinsic quark momentum in the nucleon and Fermi motion, as well as a simple model for hadronization. The model is found to describe the data well. Values of α s =0.16±0.02(stat)±0.02(syst.)±0.03(frag.) at an averageQ 2 of 15.4±0.4 GeV2/c2 and $$\Lambda _{\overline {MS} } = 216_{ - 99}^{ + 113} $$ (stat.) −90 +100 (syst.) −90 +130 , (frag.) MeV/v for three flavours are extracted.

    Notes:
    Abstract A study is presented of μe events from an exposure of BEBC, filed with an heavyH 2/Ne mixture, to a wide band antineutrino beam at the CERN SPS. The promptμ + e − rate, based on the observation of 45 events withp μ〉4 GeV/c andp e〉0.8 GeV/c, is found to be 0.31±0.05±0.02%, in agreement with previous determinations made on much smaller statistics. The differential kinematical variables characterizing the events and the content of strange particles are as expected for the production of charmed hadrons which subsequently decay semi-leptonically. An upper limit of 2.0±10−4 at 90% C.L. is given for the production rate of promptμ + e + events. No evidence is found for a significant production of Beauty hadrons.

    Notes:
    Abstract A sample of over 25,000 fully measured neutrino and antineutrino charged current interactions in BEBC includes 192 dilepton candidates. The prompt signal after subtraction of background is 41 ±7µ+ e -, 35±7µ+µ- events from $$\bar v$$ interactions, and 32±7µ-µ+ events from ν interactions. There are 2 trileptons, µ-µ- e + and µ-µ-µ+. Results are compared with other experimental data and with the standard model. Limits to prompt like sign µ+ e +, µ+µ+ and µ-µ- signals are given and compared with other experiments and with theoretical calculations.

    Abstract Neutral strange particle production in $$\bar v$$ Ne charged current interactions is studied using the bubble chamber BEBC, exposed to the CERN SPS antineutrino wide band beam. From a sample of 1191 neutral strange particles, the inclusive production rates are determined to be (15.7±0.8)% forK 0 mesons, (8.2±0.5)% for Λ, (0.4±0.2)% for $$\bar \Lambda $$ and (0.6±0.3)% for Σ0 hyperons. The inclusive production properties ofK 0 mesons and Λ hyperons are investigated. The Λ hyperons are found to be polarized in the production plane.

    Notes:
    Abstract Evidence for a significant higher twist contribution to highz π− production in antineutrino scattering is presented. In events withW〉3 GeV andQ 2〉1 GeV2 in our data, it accounts for (51 ±8)% of all π− withz above 0.5. It is consistent with thez−Q 2 correlations of Berger's higher twist prediction. The data are inconclusive concerning the predictedy−z correlation andp T dependence. Thez −Q 2 correlation is not adequately described by the Lund Monte-Carlo.

    Notes:
    Abstract The isoscalar nucleon structure functionsF 2(x, Q 2) andxF 3(x, Q 2) are measured in the range 0〈Q 2〈64 GeV2, 1.7〈W 2〈250 GeV2,x〈0.7 using ν and $$\bar v$$ interactions on neon in BEBC. The data are used to evaluate possible higher twist contributions and to determine their impact on the evaluation of the QCD parameter Λ. In contrast to previous analyses reaching to such lowW 2 values, it is found that a low $$\Lambda _{\overline {MS} } $$ value in the neighbourhood of 100 MeV describes the data adequately and that the contribution of dynamical higher twist effects is small and negative.

    Notes:
    Abstract Nearly 40000 neutrino and antineutrino interactions in BEBC are compared to measure the differences between neon and deuterium in the quark and antiquark distributions and in the nucleon structure functions. The ratio of Ne to D cross sections indicates some decrease betweenx∼0.2 andx∼0.6. They distributions show there is no significant increase in the neon sea, but prefer a small decrease. Taken altogether, thex andy distributions and the measured total cross-sections indicate some change in the shape of the valence distributions. No significant dependence onA is observed for either the shape of the sea or the ratio of longitudinal to transverse cross-sections.

    Abstract Coherent production ofρ − mesons in charged current antineutrino interactions on neon nuclei is studied in the BEBC bubble chamber exposed to the CERN SPS wide band beam. The cross section is measured to be (95±25)·10−40 cm2 per neon nucleus, averaged over the beam energy spectrum. The distributions of kinematical variables and the absolute value of the cross section are in agreement with theoretical predictions based on the CVC hypothesis and the vector meson dominance model.

    Notes:
    Abstract The average multiplicities of charged hadrons and of π+, π− and π0 mesons, produced in $$\bar v$$ Ne and νNe charged current interactions in the forward and backward hemispheres of theW ±-nucleon center of mass system, are studied with data from BEBC. The dependence of the multiplicities on the hadronic mass (W) and on the laboratory rapidity (y Lab) and the energy fraction (z) of the pion is also investigated. Special care is taken to determine the π0 multiplicity accurately. The ratio of average π multiplicities $$\frac{{2\left\langle {n_{\pi ^O } } \right\rangle }}{{[\left\langle {n_{\pi ^ + } } \right\rangle + \left\langle {n_{\pi ^ - } } \right\rangle ]}}$$ is consistent with 1. In the backward hemisphere $$\left\langle {n_{\pi ^O } } \right\rangle $$ is positively correlated with the charged multiplicity. This correlation, as well as differences in multiplicities between $$\mathop v\limits^{( - )} $$ and $$\mathop v\limits^{( - )} $$ , $$\mathop v\limits^{( - )} $$ scattering, is attributed to reinteractions inside the neon nucleus of the hadrons produced in the initial $$\mathop v\limits^{( - )} $$ interaction.

    Notes:
    Abstract The cross section for coherent production of a single π− meson in charged current antineutrino interactions on neon nuclei has been measured in BEBC to be (175±25) 10−40 cm2/neon nucleus, averaged over the energy spectrum of the antineutrino wide band beam at the CERN SPS; this corresponds to (0.9±0.1) % of the total charged current $$\bar v_\mu $$ cross section. The distributions of kinematical variables are in agreement with theoretical predictions based on the PCAC hypothesis and the meson dominance model; in particular, theQ 2 dependence is well described by a propagator containing a massm=(1.35±0.18) GeV. The absolute value of the cross section is also in agreement with the model. This analysis thus provides a test of the PCAC hypothesis in the antineutrino energy range 5–150 GeV.
