Non-linear Sigma Model Solutions for the Disoriented Chiral Condensate at O ( p 4 )

Abstract

Boost-invariant (1+1) dimensional solutions for the Disoriented Chiral Condensate (DCC) are obtained numerically, in the context of the SU(2)L ⊗ SU(2)R non-linear sigma model at O(p4) in the momentum expansion. We ignore the mass terms in the Lagrangian, as we are mainly interested in the behavior of the solutions for small values of proper time τ . The… (More)
