Pietro Giudice, Alessandro Papa
TL;DR
This paper investigates finite temperature SU(2) gauge theory with staggered fermions at real and imaginary chemical potentials, testing the analytical continuation method against direct results to validate its effectiveness.
Contribution
It provides a comparative analysis of analytical continuation and direct measurement methods for chemical potential in SU(2) gauge theory.
Findings
Analytical continuation closely matches direct results for imaginary chemical potential.
The method's validity is confirmed within certain temperature and chemical potential ranges.
Results support the use of analytical continuation in finite density QCD studies.
Abstract
In this work we study the finite temperature SU(2) gauge theory with staggered fermions for real and imaginary chemical potential. We test the method of analytical continuation of Monte Carlo results obtained for imaginary chemical potential, by comparison with those obtained {\em directly} for real chemical potential.
