摘要
利用扩展磁化有效逸度准粒子模型(EQPM)研究了动量空间各向异性对重夸克态的影响。电势的实部和虚部都通过介电函数进行了修正,其中包括各向异性参数ξ。在各向异性和恒定磁场的作用下,介质修饰电位的实部更具吸引力。研究了椭球和各向同性情况下1S、2S和1P夸克态的结合能,包括各向异性效应。我们发现Q Q¯态的结合能在各向异性的存在下变得更强。然而,发现磁场降低了结合能。研究了在恒磁场e B = 0.3 G e V 2条件下,各向同性和长向态的夏铵态和底铵态的热宽度。本文还研究了磁场对扁圆情况下1P态质谱的影响。与各向同性的情况相比,扁圆的情况下,正铵和底铵的1S、2S和1P态的解离温度要高。
Anisotropic Behavior of S-Wave and P-Wave States of Heavy Quarkonia at Finite Magnetic Field

The dissociation temperature for the 1S, 2S, and 1P states of charmonium and bottomonium has been determined to be higher for the oblate case with respect to the isotropic case.
