Parallel 29: jets with heavy quarks
- Marta Verweij (Utrecht University (NL))
Within the framework of leading power factorization formalism of nonrelativistic quantum chromodynamics, we calculate the jet fragmentation function for $J/\psi$ production in proton-proton (pp) collisions ranging from $\sqrt{s}=500$ GeV to $13$ TeV. The reasonable agreements between theory and experimental data indicate that $J/\psi$ production within a jet is mainly dominated by gluon...
Energy correlators inside of high energy jets provide a powerful tool to image the intrinsic and emergent angular scales of QCD. They have the potential to provide unprecedented insight on the interplay between vacuum scales inside of a jet and its medium modification. However, as with traditional jet substructure, experimentally these correlators will mix different angular features associated...
Jet production at the LHC provides an invaluable probe of QCD dynamics
ranging from initial-state parton distributions to final-state jet fragmentation
functions. High-precision perturbative calculations for jet substructure have
recently become available, allowing direct comparison of experimental measure-
ments to theory. Measurements of jet substructure therefore offer a direct test...
Hard-scattered partons produced early in heavy-ion collisions are used to probe the properties of the QGP (Quark-Gluon Plasma). These partons lose energy in the QGP either through elastic collisions, or through medium-induced gluon \textit{bremsstrahlung}, which is the dominant mode of energy loss for gluons and light quarks. Theoretical calculations predict that at low momentum...
Despite being a key component of the factorisation theorem used for the calculation of heavy-flavour hadron production, fragmentation functions remain poorly understood due to their non-perturbative nature and must instead be evaluated based on experimental data. Recent measurements comparing charm baryon and meson production in hadronic collisions at low and intermediate transverse momenta...
