论文摘要
我们使用准粒子方法在存在有限数量的不同风味的有限夸克化学潜力的情况下研究了重夸克尼亚的性质。有限夸克化学电位的效果已通过准粒子debye质量纳入,以检查Quarkonium态的结合能。从电势的假想部分中,我们计算了夸克尼亚基态的热宽度,并发现热宽度随有限的夸克化学电位而增加。 J/PSI和UPSILON的解离温度(T_D)已在存在有限夸克化学潜力的情况下计算出不同口味(即N_F = 1、2和3)。还研究了有限夸克化学电位对夸克状态质谱的影响。
We studied the properties of the heavy quarkonia in the presence of finite quark-chemical potential for different number of flavors by using the quasi particle approach. The effect of the finite quark-chemical potential has been incorporated through the quasi-particle Debye mass to examine the binding energies of the quarkonium states. From the imaginary part of the potential we have calculated the thermal width of the ground state of the quarkonia and found that the thermal width increases with finite quark-chemical potential. The dissociation temperature (T_D) of the J/psi and Upsilon have been calculated in the presence of finite quark-chemical potential for different flavors (i.e., N_f = 1, 2 and 3). The effect of the finite quark-chemical potential on the mass spectra of the quarkonium states has been also studied.
