Abstract

Preliminary results from measurements of resonances (K *0(892), \(\overline {K*^0 } (892)\), Φ(1020), and ρ(770)) and weakly decaying particles (Λ(1116), \(\bar \Lambda (1116)\), and K S 0 (498)) are presented. The measurements are performed at mid-rapidity by the STAR detector in \(\sqrt {s_{NN} } = 130\) GeV Au−Au collisions at RHIC. The ratios K *0/h−, \(\overline {K*^0 } /K\), and \(\bar \Lambda /\Lambda \) are compared to measurements at different energies and colliding systems. Estimates of thermal parameters, such as temperature and baryon chemical potential, are also presented.

STAR的共振研究

从测量共振(K *0(892)， \(\overline {K*^0 } (892)\)， Φ(1020)，和ρ(770))和弱衰变粒子(Λ(1116)， \(\bar \Lambda (1116)\)，和K S 0(498))的初步结果提出。在RHIC的\(\sqrt {s_{NN} } = 130\) GeV Au - Au碰撞中，STAR探测器以中速进行了测量。比较了K *0/h−、\(\overline {K*^0 } /K\)和\(\bar \Lambda /\Lambda \)在不同能量和碰撞系统下的测量值。热参数的估计，如温度和重子化学势，也提出了。
