Schottky Anomaly and Hadronic Spectrum

TL;DR

This paper proposes using the Schottky anomaly in the hadronic heat capacity as a diagnostic tool to identify different underlying scales and potentially distinguish exotic hadronic states from conventional ones.

Contribution

It introduces a novel method of analyzing hadronic spectra through heat capacity and Schottky anomaly to infer underlying dynamical structures and identify exotic states.

Findings

Heat capacity reveals multiple scales in meson spectra.

Schottky anomaly can differentiate conventional and exotic hadronic states.

Method demonstrated on well-known meson spectra.

Abstract

We show that the hadronic "heat capacity" calculated as a function of temperature may be used to infer the possible presence of different scales underlying the dynamical structure of hadronic resonances using the phenomenon of Schottky anomaly. We first demonstrate this possibility with well known meson spectrum in various channels and comment on the possibility of using this method as a diagnostic to distinguish the exotic states.
