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.

Heavy-quark production in eγ scattering [PDF]

open access: yesPhysics Letters B, 1996
Open heavy flavour production at $e^+e^-$ colliders in deeply inelastic $e $ scattering has an interesting feature: the structure function $F_2(x,Q^2)$ for this process is calculable for $x>0.01$, and is essentially proportional to the gluon density in the photon for smaller $x$ values.

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

Heavy Quark Production at CDF [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2003
The contribution summarizes the latest results from CDF on heavy quark production. Results from top, bottom and charm production are included. Some new analysis using Run I (1991-1994) data have become available. More importantly there are a number of results using Run II data which began in April 2001. The data indicate the potential of CDF for bottom

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 ...

Heavy quark jet fragmentation

open access: yesJournal of High Energy Physics, 2018
In this paper we study the fragmentation of a parton into a jet containing a heavy quark. When heavy quarks are involved in a jet, the quark mass can lead to a numerically significant correction to the jet cross section and its substructure.
