K+ production in relativistic heavy-ion collisions Academic Article uri icon

abstract

  • Recent experimental data on K+ production at 2.1 GeV/nucleon are not explained by either the cascade model or the fireball model. Here we introduce a hybrid model in which the total kaon yield is given by individual nucleon-nucleon collisions but its momentum distribution is determined by the temperature of the pion. The model is able to explain the data. The possibility of studying K+ yield as a signature for the pionic instability in heavy-ion collisions is indicated.
