Review of Charmonium and Bottomonium Quark State Production via Relativistic Heavy Ion Collisions

open access: yesUniverse, 2020
This is a review of the production of heavy quark states via relativistic heavy ion collisions in RHIC. The heavy quarks here are c, charm quark, and b, bottom quark. The states are charmonium meson states Ψ ( n S ) , with n = 1,2 and upsilon

The dynamic hadronization of charm quarks in heavy-ion collisions [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields
The Pythia8/Angantyr  model for heavy ion collisions was recently updated with a mechanism for global colour reconnection. The colour reconnection model used is QCD colour algebra inspired and enhances baryon production due to the formation of string ...

Transverse momentum distributions of heavy hadrons and polarized heavy quarks

open access: yesJournal of High Energy Physics, 2023
We initiate the study of transverse momentum-dependent (TMD) fragmentation functions for heavy quarks, demonstrate their factorization in terms of novel nonperturbative matrix elements in heavy-quark effective theory (HQET), and prove new TMD sum rules ...

A method for probing the formation of quark matter

open access: yesPhysics Letters B, 2023
Based on a multi-phase transport model for relativistic heavy-ion collisions, effects of the parton scatterings on the production of strangeness in relativistic heavy-ion collisions are studied.

Heavy quark jet production near threshold

open access: yesJournal of High Energy Physics, 2021
In this paper, we study the fragmentation of a heavy quark into a jet near threshold, meaning that final state jet carries most of the energy of the fragmenting heavy quark.

Power expansion for heavy quarkonium production at next-to-leading order in e+e− annihilation

open access: yesJournal of High Energy Physics, 2020
We study heavy quarkonium production associated with gluons in e+e − annihilation as an illustration of the perturbative QCD (pQCD) factorization approach, which incorporates the first nonleading power in the energy of the produced heavy quark pair.

Next-to-leading-order QCD corrections to Higgs production in association with a jet

open access: yesPhysics Letters B, 2023
We compute the next-to-leading-order (NLO) QCD corrections to the Higgs pT distribution in Higgs production in association with a jet via gluon fusion at the LHC, with exact dependence on the mass of the quark circulating in the heavy-quark loops.

Exotic bottomonium hadronic transitions [PDF]

open access: yesEPJ Web of Conferences, 2022
We report on a recent computation of the transitions of exotic bottomonium to standard bottomonium and light quark hadrons. We work under the assumption that the ϓ(10753) and ϓ(11020) can be described as the lowest laying and first excitation 1− − hybrid

Measurement of beauty production via non-prompt D0 mesons in Pb-Pb collisions at s NN $$ \sqrt{{\textrm{s}}_{\textrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2022
The production of non-prompt D0 mesons from beauty-hadron decays was measured at midrapidity (|y| < 0.5) in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of s NN $$ \sqrt{{\textrm{s}}_{\textrm{NN}}} $$ = 5.02 TeV with the ALICE experiment ...

Soft-parton contributions to heavy-quark production at low transverse momentum

open access: yesJournal of High Energy Physics, 2023
We consider QCD radiative corrections to the production of a heavy-quark pair in hadronic collisions. We present the computation of the soft-parton contributions at low transverse momentum of the heavy-quark pair up to second order in the QCD coupling α ...
