We argue that as the atomic number of the target nucleus A → ∞, the multiplicity of leading particles in hadron-nucleus collisions tends to a finite limit. The limiting multiplicities for various particle production are computed for both proton and pion projectiles. Signatures at finite A are discussed. Data from 100 GeV/c central hadron-nucleus collisions are analyzed and found to be in qualit...

Recent experimental data have established some of the basic features of multiple interactions in hadron–hadron collisions. The emphasis is therefore now shifting, to one of exploring more detailed aspects. Starting from a brief review of the current situation, a next-generation model is developed, wherein a detailed account is given of correlated flavour, colour, longitudinal and transverse mom...

The recent status of hard thermal photon production in relativistic heavy ion collisions is reviewed and the current rates are presented with emphasis on corrected bremsstrahlung processes in the quark-gluon plasma (QGP) and quark-hadron duality. Employing Bjorken hydrodynamics with an EOS supporting the phase transition from QGP to hot hadron gas (HHG), thermal photon spectra are computed. For...

Hadronic interactions are successfully parameterized in different models. Those most frequently applied are the Regge parameterization and the geometrical model. In the present paper we want to apply the geometrical picture to different domains of the hadronic interaction. The model used is a very economical model in that it contains only few parameters most of which have a direct physical inte...

We discuss multi-hadron production in both inelastic neutrino-nucleon interactions in the current fragmentation region and neutrino-nucleus collisions in the target fragmentation region. Our analysis, carried out within the framework of the quark-gluon string model, is mainly focused on the difference between these two processes. We show that the Q dependence of hadron multiplicity in the curre...

Abstract—Complete one-loop electroweak corrections to neutral current Drell–Yan process $$pp \to {{\ell }^{ + }}{{\ell - }}X$$ are presented for the case of longitudinal polarization initial particles. The single- and double-spin asymmetries under study allow us extract information about polarized parton distribution functions. Numerical impact next-order as function vector boson rapidity lepto...

The next generation of long-baseline neutrino experiments will be capable precision measurements oscillation parameters, neutrino-nucleus scattering, and unprecedented sensitivity to physics beyond the Standard Model. Reduced uncertainties in fluxes are necessary achieve high these future precise measurements. New hadron-nucleus interaction cross sections needed reduce fluxes. We report differe...
