energy nucleon collisions

The commonly used West and Yennie model approach to the description of the interference between Coulomb and hadronic scattering of nucleons is critically examined and its deficiencies are clarified. The preference of the more general eikonal model approach is summarized. High-energy elastic scattering of nucleons is realized mostly due to the strong hadronic interactions, and in the case of cha...

Nuclear like effects in proton-proton collisions at high energy

We show that several effects considered nuclear effects are not nuclear in the sense that they do not only occur in nucleus-nucleus and hadron-nucleus collisions but, as well, they are present in hadron-hadron (proton-proton) collisions. The matter creation mechanism in hh, hA and AA collision is always the same. The pT suppression of particles produced in large multiplicity events compared to ...

Coherence Time in High Energy Proton-nucleus Collisions

Precisely measured Drell-Yan cross sections for 800 GeV protons incident on a variety of nuclear targets exhibit a deviation from linear scaling in the atomic number A. We show that this deviation can be accounted for by energy degradation of the proton as it passes through the nucleus if account is taken of the time delay of particle production due to quantum coherence. We infer an average pro...

Quark production in high energy proton-nucleus collisions

In this note, we discuss the problem of quark-antiquark pair production in the framework of the color glass condensate. The cross-section can be calculated in closed form for the case of proton-nucleus collisions, where the proton can be considered to be a dilute object. We find that k⊥-factorization is broken by rescattering effects. PACS. 11.80.La Multiple scattering – 11.15.Kc Classical and ...

Photon production in high energy proton-nucleus collisions

We calculate the photon production cross-section in pA collisions under the assumption that the nucleus has reached the saturation regime, while the proton can be described by the standard parton distribution functions. We show that due to the strong classical field O(1/g) of the nucleus, bremsstrahlung diagrams become dominant over the direct photon diagrams. In particular, we show that γ−jet ...
