QCD light-cone distribution amplitudes of heavy mesons from boosted HQET

open access: yesJournal of High Energy Physics, 2023
Light-cone distribution amplitudes (LCDAs) frequently arise in factorization theorems involving light and heavy mesons. The QCD LCDA for heavy mesons includes short-distance physics at energy scales of the heavy-quark mass.

Mass Spectra, Radii, and Decay Widths of Toponium

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, the radial Schrodinger equation with a nonrelativistic quark potential model (NRQPM) is solved numerically by employing the shooting method. Calculated numerical wave functions (or solutions) are used to compute the masses, root mean square (RMS) radii, E1, M1 radiative transition widths, annihilation decay widths, and branching ratios of

Thermalization and quark production in spatially homogeneous systems of gluons [PDF]

open access: yesEPJ Web of Conferences
We first assemble a full set of the Boltzmann Equation in Diffusion Approximation (BEDA) for studying thermalization/hydrodynamization and quark production in out of equilibrium systems.

Heavy quark production at RHIC and LHC within a partonic transport model

open access: yes, 2010
The production and space-time evolution of charm and bottom quarks in nucleus-nucleus collisions at RHIC and LHC are investigated with the partonic transport model BAMPS (Boltzmann Approach of MultiParton Scatterings).

Differential heavy quark pair production at small x

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We consider the production of a heavy quark pair in proton–proton collisions. For bottom and charm quarks, the final state invariant mass is typically much smaller than the collider energy (e.g.

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

Ultraperipheral production of very small number of particles in ultrarelativistic heavy ion collisions *

open access: yesEPJ Web of Conferences, 2014
We review our recent results on exclusive production of μ+μ−, heavy quark - antiquark and meson-antimeson pairs in ultraperipheral, ultrarelativistic heavy ion collisions.

Extraction of the heavy-quark potential from bottomonium observables in heavy-ion collisions

open access: yesPhysics Letters B, 2019
The in-medium color potential is a fundamental quantity for understanding the properties of the strongly coupled quark-gluon plasma (sQGP). Open and hidden heavy-flavor (HF) production in ultrarelativistic heavy-ion collisions (URHICs) has been found to ...
