Baryon-antibaryon dynamics in relativistic heavy-ion collisions

Abstract: The dynamics of baryon-antibaryon annihilation and reproduction (BB ↔ 3M) is studied within the PartonHadron-String Dynamics (PHSD) transport approach for Pb+Pb and Au+Au collisions as a function of centrality from lower Super Proton Synchrotron (SPS) up to Large Hadron Collider (LHC) energies on the basis of the quark rearrangement model. At Relativistic Heavy-Ion Collider (RHIC) energies we find a small net reduction of baryon-antibaryon (BB) (2013)], where a deviation of 2.7 σ was claimed by the ALICE Colla… Show more

“…But, for higher (intermediate) beam energies (as studied in Chapter 5) the catalysis reaction have to be extended with the pion catalysis reaction: fipn ae fid [184], similar to a recent study for small collision systems at high beam energies [127]. Other authors focus on the B B annihilation reactions that produce multiple mesons [128,129,130] with the PHSD (Parton-Hadron String Dynamics) approach [240]. In their quark rearrangement model for baryon-antibaryon annihilation and reproduction, all reactions follow the scheme B B ¡ 3 mesons.…”
