Description
The nonperturbative process of hadronization has recently been the subject of intense experimental investigation at the LHC. Since heavy quark production is suppressed at the hadronization scale, heavy-flavour hadrons offer an insightful probe into this effect, connecting perturbative parton-level calculations with experimental final states. Jets produced in conjunction with heavy hadrons offer additional information about hadronic formation at various mass scales and how hadronization depends on the partonic final states. In particular, recent measurements of in-jet quarkonium production suggest significant parton shower production, where gluons split into heavy quark-antiquark pairs. This further complicates the interpretation of charmonium suppression in heavy-ion collisions as evidence of QGP formation. Jet substructure can also be used to probe the formation of exotic hadrons, whose structure is still not well understood. This talk presents recent studies of hadronization using heavy-flavour jets with the LHCb detector, including inclusive hadron production in heavy-flavor jets, as well as quarkonium and tetraquark production in jets.
Results are compared to various models of hadronization, providing strong new constraints on theoretical predictions, and offering insight into interpretations of future measurements in PbPb collisions.
