Search for the QCD critical point at SPS energies

TL;DR

This paper discusses the search for the QCD critical point at SPS energies using fluctuation measurements and spectra analysis, highlighting the potential signals and future experimental strategies at CERN's SPS.

Contribution

It presents experimental fluctuation data and spectra analysis aimed at identifying the QCD critical point, and discusses future search strategies at SPS.

Findings

Fluctuation measurements show potential signals of the critical point.

Transverse mass spectra of baryons and anti-baryons are analyzed.

Future search strategies at SPS are outlined.

Abstract

Lattice QCD calculations locate the QCD critical point at energies accessible at the CERN Super Proton Synchrotron (SPS). We present average transverse momentum and multiplicity fluctuations, as well as baryon and anti-baryon transverse mass spectra which are expected to be sensitive to effects of the critical point. The future CP search strategy of the NA61/SHINE experiment at the SPS is also discussed.
