Central exclusive diffractive production of $p \bar{p}$ pairs in proton-proton collisions at high energies

Understand

We consider the central exclusive production of the $p\bar{p}$ in the continuum and via resonances in proton-proton collisions at high energies.

• We discuss the diffractive mechanism calculated within the tensor-pomeron approach including pomeron, odderon, and reggeon exchanges.
• The theoretical results are discussed in the context of existing WA102 and ISR experimental data and predictions for planned or current experiments at the RHIC and the LHC are presented.
• The distribution in ${\rm y}_{diff}$, the rapidity distance between proton and antiproton, is particularly interesting.
