Isospin susceptibility in the O(n) sigma-model in the delta-regime
Abstract We compute the isospin susceptibility in an effective O(n) scalar field theory (in d = 4 dimensions), to third order in chiral perturbation theory (χPT) in the delta-regime using the quantum mechanical rotator picture. This is done in the presence of an additional coupling, involving a para...
