Near-threshold pion production with radioactive beams
Near-threshold pion production with radioactive beams
Using an isospin- and momentum-dependent transport model we study near-threshold pion production in heavy-ion collisions induced by radioactive beams at the planned rare isotope accelerator (RIA). We revisit the question of probing the high-density behavior of nuclear symmetry energy ${E}_{\mathrm{sym}}(\ensuremath{\rho})$ using the ${\ensuremath{\pi}}^{\ensuremath{-}}/{\ensuremath{\pi}}^{+}$ ratio. It is found that both the …
