Two pion bound states in a hot pion gas
arXiv:nucl-th/9311003
Abstract
The occurrence of poles in the propagator in a hot pion medium is studied. The domain of non--trivial solutions to the corresponding bosonic gap equation is investigated as a function of the chemical potential and temperature of the gas.
