Absolute inclusive cross sections for \(\bar pp\) interactions at 7.3 GeV/c are given. The data cover prong cross sections,V 0, γ production and inclusive charged particle (p/π) production. Separation has been made into annihilation and non-annihilation components. Inclusive π+, π? production in the processes of \(\bar pp\) annihilation and non-annihilation are compared with simple quark models. 相似文献

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. 相似文献

We have estimated cross sections for the production of resonances in the reactions K?p → Λ0 + pions. The data have also been analysed by a method which examines event-to-event fluctuations. Within the framework of the simple parametrization of resonance production assumed, the contribution from the resonances is insufficient to explain the observed fluctuations in the longitudinal emission of the final-state particles. These features are well reproduced by an independent cluster emission model. 相似文献

In high energye + e ? annihilations, events with jets dominate. Since heavy quark jets often contain undetectable neutrinos, methods of jet analysis are needed to study such events. A simple procedure is presented here and illustrated by applying to the search for the neutral Higgs bosonH 0 produced at LEP at the center-of-mass energy of 200 GeV. 相似文献
