论文摘要
我们研究了哈德子之间排斥相互作用对保守电荷波动的影响。我们计算了Baryon，电荷和强体共振气体模型范围内的陌生敏感性扩展到包括短距离排斥性相互作用。通过平均场方法，包括平均粒子能量通过均值的现场相互作用来修改，这是由于HADRON之间的平均现场相互作用而修改的，因为Hadrons之间的平均现场相互作用与Hadrons相互作用到HadRons之间。结果表明，排斥性相互作用在过渡温度附近描述雄性物质起着非常关键的作用。我们还表明，为了始终如一地描述高阶保守的电荷波动，不能忽略中音排斥相互作用。此外，我们证明了重子的排斥性相互作用对于描述有限的bary级化学潜力的晶格模拟结果至关重要。
We investigate the effects of repulsive interaction between hadrons on the fluctuations of the conserved charges. We calculate the baryon,the electric charge and the strangeness susceptibilities within the ambit of hadron resonance gas model extended to include the short range repulsive interactions.The repulsive interactions are included through a mean-field approach where the single particle energy gets modified due to mean field interactions between hadrons proportional to the number density of hadrons.We assume different mean-field interactions for mesons and baryons. It is shown that the repulsive interactions play a very crucial role to describe hadronic matter near transition temperature. We also show that in order to consistently describe higher order conserved charge fluctuations mesonic repulsive interactions cannot be neglected. Further, we demonstrate that the repulsive interaction of baryons are essential to describe the lattice simulation results at finite baryonchemical potential for higher order fluctuations.
