SQCD中的质谱和Seiberg对偶问题另一场景

Mass Spectrum in SQCD and Problems with the Seiberg Duality. Another Scenario

Victor L. Chernyak

摘要:

在夸克只能处于两种不同相态的动力学假设下,考虑了具有SU(N_c)色和N_F味的N=1的SQCD。这些是:a)HQ(重夸克)相,在那里它们被限制,b)或者它们被higgsed,在拉格朗日参数的适当值处。质量谱的(直接)理论和Seiberg的对偶得到和比较,夸克的质量相等或不等。结果表明,在任何情况下,当有一个小参数(直接理论为0<(3 N_c-N_F)/N_F << 1,对偶理论为0<(2N_F-3N_c)/N_F << 1)时,直接理论和对偶理论的质谱都是参数不同的。还考虑了其他一些制度。

英文摘要:

N=1 SQCD with SU(N_c) colors and N_F flavors of light quarks is considered within the dynamical scenario which assumes that quarks can be in two different phases only. These are: a) either the HQ (heavy quark) phase where they are confined, b) or they are higgsed, at the appropriate values of parameters of the Lagrangian. The mass spectra of this (direct) theory and its Seiberg's dual are obtained and compared, for quarks of equal or unequal masses. It is shown that in all cases when there is the additional small parameter at hand (it is 0<(3N_c-N_F)/N_F << 1 for the direct theory, or its analog 0<(2N_F-3N_c)/N_F << 1 for the dual one), the mass spectra of the direct and dual theories are parametrically different. A number of other regimes are also considered.
