关于QCD振幅的Casimir算子依赖性

On the Casimir operator dependences of QCD amplitudes

T. Grandou

摘要:

至少在程函近似和猝灭近似下,我们认为,借助于新发现的有效定域性,得到的强耦合费米子QCD振幅,与在基本规范群表象上计算的唯一的$SU_c(3)$二次Casimir算符的依赖性不同。这个结果与微扰理论形成对比,但也与许多非微扰方法如MIT Bag、随机真空模型和格点模拟形成对比,相反,该结果解释了秩2 $SU_c(3)$ -李代数的全部代数内容

英文摘要:

In eikonal and quenched approximations at least, it is argued that the strong coupling fermionic QCD amplitudes obtained with the help of the newly discovered effective locality property, depart from a dependence on the sole $SU_c(3)$ quadratic Casimir operator, evaluated over the fundamental gauge group representation. This result, in contradistinction with Perturbation Theory, but also with a number of non-perturbative approaches such as the MIT Bag, the Stochastic Vacuum Models, and Lattice simulations, accounts, instead, for the full algebraic content of the rank-2 $SU_c(3)$-Lie algebra
