Effects of pion potential and nuclear symmetry energy on the pi(-)/pi(+) ratio in heavy-ion collisions at beam energies around the pion production threshold

AbstractWithin the framework of the isospin-dependent Boltzmann-Uehling-Uhlenbeck (IBUU) transport model, we studied the effects of the pion potential and the symmetry energy on the pion production in central Au-197 + Au-197 collisions around the pion production threshold. It is found that the pion potential has opposite effects on the value of the pi(-)/pi(+) ratio at low and high pion energies. The effect of the pion potential on the total pi(-)/pi(+) ratio becomes larger in heavy-ion collisions at beam energies below the pion production threshold. At beam energies below the pion production threshold, with the pion potential, the effect of the symmetry energy on the pi(-)/pi(+) ratio becomes smaller compared with that above the pion production threshold.
