24. Recent experimental results on charge exchange reactions with VES setup

Юрий Хохлов (ИФВЭ)

24/07/2025, 15:00

(OFFLINE)
Two topics on charge exchange (ChEx) production of exclusive systems of light mesons by pions on nuclei will be presented. The first one is the completed study of the omega(782) phi(1020) channel with the dominance of the scalar isoscalar resonance f0(1710), which characteristics point to its glueball-like nature. The second one is a preliminary report on the first observation of...

Diffraction on nuclei

(OFFLINE)
Recent results of proton-Pb collisions with large forward rapidity gap events at the LHC show a dominant role of photon exchange over pomeron one.
A comparison of LHC proton-proton, proton-nuclear forward rapidity gap events provides an opportunity for the estimation of
A- and Z- dependencies of pomeron- and photon- exchange contributions, respectively.

Abstract By using the Reggeometric Pomeron model for vector meson production which successfully describes the high energy lepton-nucleon data, we analyze the...
