Advances in High Energy Physics, Volume 2024, Issue 1, 2024.In this study, we investigated the impact of a topological defect (λ) on the properties of heavy quarkonia using the extended Cornell potential. We solved the fractional radial Schrödinger equation (SE) using the extended Nikiforov‐Uvarov (ENU) method to obtain the eigenvalues of energy, which allowed us to calculate the masses of charmonium and ...

Jet quenching of the heavy quarks in the quark-gluon plasma and the nonadditive statistics
Physics Letters BUsing the Plastino-Plastino (PP) equation, we calculate transport coefficients of the heavy-quarks traversing inside the quark-gluon plasma, and generalize their relationship with differential energy loss. The PP equation indicates anomalous diffusion of

Ausbreitung von Jets und Entstehung von Machkegeln in (3+1) dimensionaler idealer Hydrodynamik [PDF]
, 2009 This thesis investigates the jet-medium interactions in a Quark-Gluon Plasma using a hydrodynamical model. Such a Quark-Gluon Plasma represents a very early stage of our universe and is assumed to be created in heavy-ion collisions.

Charmonium production and elliptic flow in relativistic heavy-ion collisions
EPJ Web of Conferences, 2011 Using the two-component model for charmonium production, which includes contributions from both initial hard nucleon-nucleon scattering and from regeneration in the quark-gluon plasma, we have studied the nuclear modification factor RAA and elliptic flow

Heavy quarkonium dissociation by thermal gluons at next-to-leading order in the Quark–Gluon Plasma
Physics Letters B, 2018 Using the chromo-electric dipole coupling Hamiltonian from QCD multipole expansion, we derive the dissociation cross sections of heavy quarkonia by thermal gluons at next-to-leading order (NLO, also known as inelastic parton scattering dissociation) in ...

Static and dynamic properties of the pion from continuum modelling of strong QCD [PDF]
, 2010 We present nonperturbative numerical solutions for the quark propagator Schwinger-Dyson equation (SDE) and pseudoscalar meson Bethe-Salpeter equation (BSE) at and beyond the rainbow-ladder truncation level of this system of equations.

JET CONVERSIONS IN QUARK-GLUON PLASMA
, 2011 In addition to loosing energy, a quark or gluon jet traversing through a quark-gluon plasma can also be converted to a gluon or quark jet through scattering with the thermal quarks and gluons. Their conversion rates due to two-body elastic [Formula: see

Dynamic scaling and quenching for heavy quark in the linear expanding medium
European Physical Journal C: Particles and FieldsWe study the energy loss of the heavy quark and the heavy quark jet propagating through linear expanding quark–gluon plasma (QGP). We show that the concept of scaling is valid for heavy quarks, with the quenching parameter of the equivalent static media ...

Direkte Photonen in Schwerionenkollisionen [PDF]
, 2011 Direct photon emission from heavy-ion collisions has been calculated and compared to available experimental data. Three different models have been combined to extract direct photons from different environments in a heavy-ion collision: Thermal photons ...
