THERMODYNAMICS OF PION GAS-USING STATES PREDICTED FROM K-DEFORMED POINCARE ALGEBRA

kappa-deformed Poincare algebra, which preserves rotational and transl ational symmetries, can successfully predict the angular and radial ex cited states of the pion. In a thermal bath with temperature, T, these states can be excited in the pion gas, in addition to the usual momen tum excitation. We exploit this situation to look at the pion free ene rgy, to find that it increases linearly with T. The energy per particl e and the entropy show interesting structures around T = 0.2 GeV.
