规范耦合常数、复合性和超对称性

Gauge coupling constant, compositeness and supersymmetry

Kazunari Shima, Motomu Tsuda

摘要:

指出在超对称理论中,裸规范耦合常数的大小可能是在全粒子复合模型中由理论确定的。我们明确地表明,在两个时空维度,NL/L超对称关系(即,所有粒子的超对称复合条件)确定了裸电磁耦合常数的大小(即,精细结构常数)。

英文摘要:

We point out the possibility that the magnitude of the bare gauge coupling constant is determined theoretically in a composite model of all particles in SUSY theories. We show explicitly in two space-time dimensions that the NL/L SUSY relation (i.e., a SUSY compositeness condition for all particles) between N = 2 LSUSY QED and N = 2 NLSUSY determines the magnitude of the bare electromagnetic coupling constant (i.e., the fine structure constant) of N = 2 LSUSY QED.
