Heavy Quarkonium Spectrum and Decay Constants from a Neural-Network-Based Holographic Model

Yu Zhang, Xun Chen, Miguel Angel Martin Contreras

We present a data-driven inverse construction of the dilaton field in a bottom-up AdS/QCD description of heavy vector quarkonia. Instead of adopting an \emph{ad hoc} analytic ansat…

The Potential Energy of Heavy Quarkonium in Flavor-Dependent Systems from a Holographic Model

Xi Guo, Xun Chen, Dong Xiang +2

Within the framework of the Einstein-Maxwell-Dilaton (EMD) model, which incorporates information on the equation of state and baryon number susceptibility from lattice results, we…

A holographic bottom-up approach to $Σ$ baryons

Xi Guo, Miguel Angel Martin Contreras, Xun Chen +1

In this work, we discuss the description of neutral $Σ$ baryons with $I (J^{P}) = 1 (1/ 2^{+})$ and $I (J^{P}) = 1 (3/ 2^{+})$ using two bottom-up approaches: the deformed background and the static…

String-breaking of the triply heavy baryon at finite temperature and chemical potential

Jia-Jie Jiang, Xun Chen, Jiajia Qin +1

In this work, we use gauge/gravity duality to study potential energy and string-breaking of triply heavy baryons at finite temperature and chemical potential. Two different possibl…
