Holographic imaginary potential of a quark antiquark pair in the presence of gluon condensation

S Tahery, X Chen, Z Zhang - Journal of High Energy Physics, 2023 - Springer
A bstract For a moving heavy quark antiquark (QQ) in a quark gluon plasma (QGP), we use
gauge/gravity duality to study both real and imaginary parts of the potential (\(\operatorname …

Screening length in a soft wall AdS/QCD model

X Zhu, P Wu, Z Zhang - The European Physical Journal A, 2024 - Springer
We study the screening length of a moving heavy quarkonium (ie, QQ¯ pair) at finite
temperature and chemical potential using a soft wall AdS/QCD model with conformal …

[HTML][HTML] Effects of the hyperscaling violation and dynamical exponents on the imaginary potential and entropic force of heavy quarkonium via holography

M Kioumarsipour, J Sadeghi - The European Physical Journal C, 2021 - Springer
The imaginary potential and entropic force are two important different mechanisms to
characterize the dissociation of heavy quarkonia. In this paper, we calculate these two …

Running coupling constant at finite chemical potential and magnetic field from holography

X Chen, L Zhang, D Hou - Chinese Physics C, 2022 - iopscience.iop.org
According to gauge/gravity duality, we use an Einstein-Maxwell-dilaton (EMD) model to
study the running coupling constant at finite chemical potential and magnetic field. First, we …

Jet quenching parameter from a soft wall AdS/QCD model

X Zhu, Z Zhang - Chinese Physics C, 2020 - iopscience.iop.org
We study the effect of chemical potential and nonconformality on the jet quenching
parameter in a holographic QCD model with conformal invariance broken by background …
