TL;DR
This paper investigates a deconfining phase transition in pure SU(2)xU(1) lattice gauge theory at zero temperature, using Monte Carlo simulations to explore potential alternatives to the Higgs mechanism.
Contribution
It demonstrates the existence of a deconfining phase transition in SU(2) gluon fields induced by a modified Wilson action, highlighting a novel phase structure.
Findings
Deconfining phase transition observed in SU(2) sector.
Transition induced by added term in Wilson actions.
Potential implications for alternative symmetry breaking mechanisms.
Abstract
Markov chain Monte Carlo simulations of pure SU(2)xU(1) lattice gauge theory show a (zero temperature) deconfining phase transition in the SU(2) gluon sector when a term is added to the SU(2) and U(1) Wilson actions, which requires joint U(2) gauge transformations of the SU(2) and U(1) vector fields. Investigations of this deconfined phase are of interest as it could provide an alternative to the Higgs mechanism.
