“…In this work, we make use of the gauge invariant Pauli-Villars regularization scheme [27,37,48,93,[97][98][99][100], where the quark momentum runs formally from zero to infinity. The three parameters in the Pauli-Villars regularized NJL model, namely the current quark mass m 0 = 5 MeV, the coupling constant G = 3.44 GeV −2 and the Pauli-Villars mass parameter Λ = 1127 MeV are fixed by fitting the chiral condensate ψψ = −(250 MeV) 3 , pion mass m π = 134 MeV and pion decay constant f π = 93 MeV in vacuum with T = µ = 0 and eB = 0. In our current calculations, we consider the situation with finite temperature and magnetic field and vanishing quark chemical potential µ = 0.…”
