Statistical Bootstrap analysis of S+Ag interaction at 200AGeV: Evidence of a phase beyond the hadronic one?

TL;DR

This paper extends the Statistical Bootstrap Model to include independent up and down quark fugacities, analyzing S+Ag collision data at 200 GeV/nucleon, suggesting the produced system may be beyond the hadronic phase.

Contribution

The paper introduces a generalized SSBM with separate quark fugacities to better analyze non-isospin symmetric heavy ion collision data.

Findings

Evidence suggests the source may lie outside the hadronic domain.

The model accounts for isospin asymmetry in heavy ion collisions.

Analysis indicates possible phase beyond the hadronic one.

Abstract

A generalized Strangeness-incorporating Statistical Bootstrap Model (SSBM) is constructed so as to include indepedent fugacities for up and down quarks. Such an extension is crucial for the confrontation of multiparticle data emerging from heavy ion collisions, wherein isospin symmetry is not satisfied. Two constraints, in addition to the presence of a critical surface which sets the boundaries of the hadronic world, enter the extended model. An analysis pertaining to produced particle multiplicities and ratios is performed for the S+Ag interaction at 200 GeV/nucleon. The resulting evaluation, concerning the location of the source of the produced system, is slightly in favor the source being outside the hadronic domain.
