TL;DR

This paper investigates the behavior of light flavor quarks at high temperature using a holographic model, revealing a phase transition and analyzing quark interactions in the deconfinement phase.

Contribution

It introduces a new holographic model with a D7 brane in a deconfinement background to study phase transitions and quark properties at high temperature.

Findings

Identified a phase transition marked by a jump in quark bilinear vacuum expectation value.

Observed a discontinuity in the derivative of D7 brane energy at the critical temperature.

Analyzed quark-antiquark potential to explore bound states in the deconfinement phase.

Abstract

Gauge theory with light flavor quark is studied by embedding a D7 brane in a deconfinement phase background newly constructed. We find a phase transition by observing a jump of the vacuum expectation value of quark bilinear and also of the derivative of D7 energy at a critical temperature. For the model considered here, we also study quark-antiquark potential to see some possible quark-bound states and other physical quantities in the deconfinement phase.
