Modification of heavy quark hadronization in high-multiplicity collisions at LHCb
Chenxi Gu
Abstract:The baryon-to-meson and meson-to-meson production ratios of heavy quarks are well suited to study the hadronization mechanism. Here we will present LHCb results on the production ratios of π΅ 0 π /π΅ 0 , π· + π /π· + and Ξ + π /π· 0 in differents collision systems. These measurements show crosssections ratios π΅ 0 π /π΅ 0 , π· + π /π· + increase with multiplicity and imply that there may be hadronization mechanisms other than fragmentation mechanisms in high-multiplicity collisions.
