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 ...
متن کاملStatus and prospects of di-jet production in high-energy polarized proton-proton collisions at RHIC
The STAR experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) is carrying out a spin physics program colliding transversely or longitudinally polarized proton beams at √ s = 200−500 GeV to gain deeper insight into the spin structure and dynamics of the proton. These studies provide fundamental insight into Quantum Chromodynamics (QCD). One of the main...
متن کاملPhoton + Hadron Production in High Energy Deuteron (Proton)-Nucleus Collisions
We apply the Color Glass Condensate formalism to photon + hadron production cross section in high energy deuteron (proton)-gold collisions at RHIC. We investigate the dependence of the production cross section on the angle between the produced hadron and photon for various rapidities and transverse momenta. It is shown that the angular correlation between the produced hadron and photon is a sen...
متن کاملQuark 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 ...
متن کاملPhoton 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 ...
