Photon and Pomeron-induced Production of Dijets in pp, pA and AA Collisions

Abstract

In this paper we present a detailed comparison of the dijet production by photon-photon, photon-pomeron and pomeron-pomeron interactions in pp, p A and AA collisions at the LHC energy. The transverse momentum, pseudorapidity and angular dependencies of the cross sections are calculated at LHC energy using the Forward Physics Monte Carlo (FPMC), which allows one to obtain realistic predictions for the dijet production with two leading intact hadrons. We see that the γ IP channel is dominant at forward rapidities in pp collisions and in the full kinematical range in the nuclear collisions of heavy nuclei. Our results indicate that the analysis of dijet production at the LHC can be useful to test the resolved pomeron model as well as to constrain the magnitude of the absorption effects.

Exclusive and diffractive μ+μ− production in pp collisions at the LHC

“…In what follows we present our results for the dimuon production by photon -photon, Pomeron -Pomeron and Pomeron -Reggeon interactions in pp collisions at the Run 2 LHC energy (For a similar analysis for the heavy quark and dijet production see Refs. [28,48,50]). As discussed in the Introduction, these processes are characterized by two rapidity gaps and intact hadrons in the final state.…”

Exclusive and diffractive $$\gamma \gamma $$ production in PbPb collisions at the LHC, HE-LHC and FCC

“…In our analysis we will estimate S 2 eik considering the approach proposed in Ref. [46], which generalizes the model described in Ref. [42] for coherent double exchange processes in nuclear collisions.…”

“…A detailed description of this approach is presented in Appendix A of Ref. [46]. The resulting predictions for PbPb collisions at √ s = 5.5, 10.6 and 39 TeV are 3.4 × 10 −5 , 2.1 × 10 −5 and 1.0 × 10 −5 , respectively.…”

Double heavy quarkonium production in diffractive processes at the Run 2 LHC energy

“…Refs. [55][56][57][58][59][60][61][62][63]) with reasonable success to describe the current data. However, as the effects that determine the gap survival factor have nonperturbative nature, they are difficult to treat, and its magnitude is strongly model dependent (for recent reviews, see Refs.…”
