Energy Formula

In this paper, we consider the exclusive production of proton–antiproton pairs in the interaction between two quasireal photons in [Formula: see text] collision. The differential and total cross-section of the process [Formula: see text] at a beam energy of photons from 2.1 GeV to 4.5 GeV in the center-of-mass and for different values of [Formula: see text] is calculated. At energy [Formula: see text] the total cross-section process of the [Formula: see text] is calculated by the two-photon mechanism. The results are in satisfactory agreement with the experimental data.

We present the current status of the study at the Tevatron, of the exclusive processes: [Formula: see text] and [Formula: see text], produced via two photon interactions; [Formula: see text], [Formula: see text] and [Formula: see text] from Double Pomeron Exchange (DPE); and, [Formula: see text], [Formula: see text] and [Formula: see text]; from photon-pomeron fusion (photoproduction). In closing we briefly discuss the plans for, and benefits of, studying exclusive physics at the LHC.

We report on a detailed investigation of four-body pp → ppπ+π- and [Formula: see text] reactions which constitute an irreducible background to three-body processes pp → ppM, where M is a broad resonance in the π+π- channel, e.g. M = σ, ρ0, f0(980), f2(1275), f0(1500). We include double-diffractive contribution (both pomeron and reggeon exchanges) as well as the pion-pion rescattering contributions. The first process dominates at higher energies and small pion-pion invariant masses while the second becomes important at lower energies and higher pion-pion invariant masses. We compare our results with the experimental data. We make predictions for future experiments at PANDA, RHIC, Tevatron and LHC energies. The two-dimensional distribution in rapidity space of pions (yπ+, yπ-) is particularly interesting. The higher the incident energy, the higher preference for the same-hemisphere emission of pions. The processes considered constitute a sizeable contribution to the total nucleon-nucleon cross section as well as to pion inclusive cross section.
