Colliding pomerons.

Khoze, V A and Martin, A D and Ryskin, M G (2019) 'Colliding pomerons.', Journal of physics G : nuclear and particle physics., 46 (11). 11LT01.


We recall the main properties of inclusive particle distributions expected for Pomeron-proton and Pomeron–Pomeron interactions. Due to the small size of the Pomeron we expect larger transverse momenta of secondaries and a smaller probability of multiple interactions, that is a narrower multiplicity distribution. We propose to compare the spectra of secondaries produced in the Pomeron and the proton interactions in terms of the Feynman xF variable. The main difference should be observed for a relatively large xF, that is near the edge of rapidity gaps. Such data offer the opportunity to illuminate the properties of the ‘soft’ or ‘Regge’ Pomeron, which drives the minimum-bias type of events in high energy pp interactions. Besides this, there should be a good opportunity to observe a glueball in the Pomeron fragmentation region.
