Vector and axialvector mesons at nonzero temperature within a gauged linear sigma model

Stefan Strüber, Dirk H. Rischke

We consider vector and axialvector mesons in the framework of a gauged linear sigma model with chiral $U(N_f{)}_R\times U(N_f{)}_L$ symmetry. For $N_f=2$, we investigate the behavior…
