[en] Some preliminary results are presented on an inclusive analysis of anti NN annihilations between 0. and 1.0 GeV/c incident anti p momentum. Inclusive K⁰₁ distributions are considered and discussed in the framework of the thermodynamical model. (L.M.K.)

[en] Assuming that the sea quark distribution vanishes for chi>0.3, we analyse the F₂sup(Fe)(chi, Q²) and F₂sup(D)(chi, Q²) structure functions measured by the European Muon Collaboration in the framework of a thermodynamical model of the valence quarks. The experimental ratio F₂sup(Fe)(chi)/F₂sup(D)(chi) is well reproduced over the whole chi range by the ratio of two valence quark distributions at different temperature T and confinement volumes V. We obtain Tsub(D)-Tsub(Fe)approx.=3 MeV and Vsub(Fe)/Vsub(D)approx.=1.3. (orig.)

[en] If the valence quarks in the nucleon are considered as a gas of the non-interacting massless particles, an expression of the xF₃(x) structure function is obtained which reproduces very well the experimental ν(anti ν)N data in the range 0.1 approx. <= x approx. <= 0.8. The effective temperature of such a quarks gas is found to be of the order of 50 MeV. (orig.)

[en] Recent CDHS results enable us to verify that the nucleon valence quark distribution has a thermodynamical behaviour for x > 0.1 with a temperature decreasing with increasing Q². Using a thermodynamical form as an input to an approximate first order QCD Q² evolution we obtain a good fit for 5 < Q² < 100 (GeV/c)². There are indications that a small Q² [Q² proportional 1 (GeV/c)²] the quark gas temperature is of the order of the temperature measured in hadronic interactions. (orig.)

[en] We analyse the chiusub(v)(chi) and chidsub(v)(chi) experimental distributions in the framework of a thermodynamical model already applied to the valence quarks. We find that usub(v)(chi) and dsub(v)(chi) can be described by the same Boltzmann type distribution at different temperatures and normalizations. (orig.)

[en] The π and K meson valance structure functions are analysed in the framework of a thermodynamical model already applied to the nucleon. We obtain a simple expression which reproduces quite well the data for chi > 0.3. The effective temperatures are found to be of the order of 20 MeV for the pion and 65 MeV for the kaon. (orig.)

[en] A search for relativistic fractionally charged particles in (anti)neutrino-deuterium interactions was performed using the CERN SPS wide-band neutrino beam and the Big European Bubble Chamber. The experiment established the following upper limit: quark/event <5 x 10/sup -5/ (90% confidence level) for charged particles with 0.3e< q<0.7e, interaction length λ>0.02λ/sub π/, and mass m/sub q/<0.5 GeV.

[en] The reactions antipp→3π^-3π⁺ and antipp→3π^-3π⁺π⁰ have been studied at 1.00 1.04 and 1.13GeV/c incident momentum. Total cross-sections and angular distributions are presented. The contributions of the various intermediate states to the final states have been determined by the maximum-likelihood method. The most important intermediate states results to be epsilon epsilonrho in the 6π annihilation and apsilonrhodeg in the 7π annihilation
