Accelerating towards an ambidextrous world: chiral symmetry restoration by the Unruh effect
Abstract:In this presentation we shall consider the possibility of triggering the chiral phase transition of QCD through uniform acceleration, i.e. by the Unruh effect. Using Chiral Perturbation Theory at leading order and in the large N limit (with N being the number of pions) as the effective description of low-energy QCD, and the Thermalization Theorem formalism to compute the relevant partition function for the accelerated observer, we are able to find that chiral symmetry is restored for accelerations higher than the critical value a_c = 4 π f_π, where f_π is the pion decay constant. Therefore, our results are in complete agreement with those obtained in the inertial, finite-temperature case.
