Open heavy flavor measurements in d+Au collisions at PHENIX experiment
EPJ Web of Conferences, 2014 The heavy quarks produced in the early stage of heavy-ion collisions are very effective probes of the dense partonic medium produced at RHIC. PHENIX has the ability to measure heavy quark production through single electrons in the central arm ...

On the Fragmentation Function for Heavy Quarks in e+e- collisions [PDF]
, 1997 We use a recent O(alpha_s^2) calculation of the differential cross section for the production of heavy quarks in e+e- annihilation to compute a few moments of the heavy quark single-inclusive production cross section.

Enhanced heavy quark-pair production in strong SU(2) color field
, 2009 Non-perturbative charm and bottom quark-pair production is investigated in the early stage of heavy ion collisions. Following our earlier works, the time-dependent study is based on a kinetic description of fermion-pair production in strong non-Abelian ...

Heavy meson masses and decay constants from relativistic heavy quarks in full lattice QCD [PDF]
, 2012 We determine masses and decay constants of heavy-heavy and heavy-charm pseudoscalar mesons as a function of heavy quark mass using a fully relativistic formalism known as Highly Improved Staggered Quarks for the heavy quark.

Theoretical aspects of heavy-flavour production at ultra-high cosmic ray energies
EPJ Web of Conferences, 2015 The main theoretical aspects of heavy-flavour production at ultra-high cosmic ray energies are reviewed, with particular emphasis in the new dynamical effects which are expected to be present in the kinematical range probed by the IceCube and Pierre ...

A fragmentation-based study of heavy quark production
Journal of High Energy Physics, 2020 Processes involving heavy quarks are a crucial component of the LHC physics program, both by themselves and as backgrounds for Higgs physics and new physics searches. In this work, we critically reconsider the validity of the widely-adopted approximation

Quark Gluon Plasma Diagnostics in a Successive Equilibrium Scenario [PDF]
, 1997 The relativistic Fokker Planck equation has been used to study the evolution of the quark distribution in the quark gluon phase expected to be formed in ultra-relativistic heavy ion collisions.

Photon production from an anisotropic quark-gluon plasma [PDF]
, 2006 We calculate photon production from a quark-gluon plasma which is anisotropic in momentum space including the Compton scattering and quark/anti-quark annihilation processes.

Heavy Flavour Working Group Summary
, 2012 We review theoretical and phenomenological aspects of heavy flavour production as discussed in the heavy flavour working group of the DIS 2012. Recent theoretical progress includes approximate NNLO calculations for heavy quark structure functions in deep

Polarized double-virtual amplitudes for heavy-quark pair production
Journal of High Energy Physics, 2018 We present the two-loop virtual amplitudes for heavy-quark pair production in light quark-antiquark annihilation and gluon fusion channels, including full spin and color dependence. We use expansions around kinematical limits and numerical integration to
