Soft Gluon Radiation off Heavy Quarks beyond Eikonal Approximation

Advances in High Energy Physics, 2016
We calculate the soft gluon radiation spectrum off heavy quarks (HQs) interacting with light quarks (LQs) beyond small angle scattering (eikonality) approximation and thus generalize the dead-cone formula of heavy quarks extensively used in the ...

Classical gluon production amplitude in heavy-ion collisions

EPJ Web of Conferences, 2016
The initial condition for the formation of the Quark-Gluon Plasma, the distribution of quarks and gluons produced in the initial stages of nuclear collisions, is the fundamental building block of heavy-ion theory.

Applying Bayesian parameter estimation to relativistic heavy-ion collisions: simultaneous characterization of the initial state and quark-gluon plasma medium [PDF]

, 2016
We quantitatively estimate properties of the quark-gluon plasma created in ultrarelativistic heavy-ion collisions utilizing Bayesian statistics and a multiparameter model-to-data comparison.

Discovery of Quark-Gluon Plasma: Strangeness Diaries [PDF]

The European Physical Journal Special Topics, 2019
We look from a theoretical perspective at the new phase of matter, quark-gluon plasma (QGP), the new form of nuclear matter created at high temperature and pressure.

A divergence-free method to extract observables from correlation functions

Physics Letters B, 2015
Correlation functions provide information on the properties of mesons in vacuum and of hot nuclear matter. In this work, we present a new method to derive a well-defined spectral representation for correlation functions.

The complex heavy-quark potential in an anisotropic quark-gluon plasma — Statics and dynamics

Journal of High Energy Physics, 2022
We generalize a complex heavy-quark potential model from an isotropic QCD plasma to an anisotropic one by replacing the Debye mass m D with an anisotropic screening mass depending on the quark pair alignment with respect to the direction of anisotropy ...

Gluon Condensate and Non-Perturbative Quark-Photon Vertex [PDF]

, 1999
We evaluate the quark-photon vertex non-perturbatively taking into account the gluon condensate at finite temperature. This vertex is related to the previously derived effective quark propagator by a QED like Ward-Takahashi identity.

Calculating the equation of state of dense quark-gluon plasma using the complex Langevin equation [PDF]

Physical Review D, 2019
The pressure and energy density of the quark-gluon plasma at finite baryon chemical potential are calculated using the Complex Langevin equation. The stout smearing procedure is generalized for the SL(3,$\mathcal{C}$) manifold allowing the usage of an ...
