Combined chiral and diquark fluctuations along QCD critical line and enhanced baryon production with parity doubling

TL;DR

This paper proposes that combined chiral and diquark fluctuations along the QCD phase boundary could cause anomalous baryon production, which might be observable at NICA.

Contribution

It introduces the concept of large combined chiral and diquark fluctuations along the QCD critical line and suggests their experimental detection through baryon production.

Findings

Large combined fluctuations are expected along the QCD phase boundary.

Such fluctuations may lead to enhanced baryon and parity partner production.

Potential experimental detection at NICA is proposed.

Abstract

We argue that there should exist the large combined fluctuations of chiral and diquark condensates along the phase boundary of QCD at moderately high density and relatively low temperature. Such fluctuations might lead to anomalous production of nucleons and its parity partner, which we propose to detect at NICA.
