Christ-Lee模型:BRST形式化的(反)手征超变量方法

Christ-Lee Model: (Anti-)Chiral Supervariable Approach to BRST Formalism

B. Chauhan, S. Kumar

摘要:

我们得到了二阶绝对反交换的Becchi-Rouet-Stora-Tyrant(BRST)的离壳幂零性,利用(反)手征超变量方法(ACSA)对一维(0 + 1)时空中Christ Lee(CL)模型的反BRST和(反)co-BRST对称性变换进行了研究,其中量子对称性[即(反)BRST和(反)co-BRST]不变量起着至关重要的作用。我们证明了幂零性和绝对反交换性的(反)BRST随着(反)合作BRST保守的收费范围内的ACSA BRST形式主义,我们只考虑一个格拉斯曼变量。我们还显示了(反)BRST和(反)协BRST的拉格朗日ACSA范围内的不变性。

英文摘要:

We derive the off-shell nilpotent of order two and absolutely anti-commuting Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST and (anti-)co-BRST symmetry transformations for the Christ--Lee (CL) model in one (0 + 1)-dimension (1D) of spacetime by exploiting the (anti-)chiral supervariable approach (ACSA) to BRST formalism where the quantum symmetry [i.e. (anti-)BRST along with (anti-)co-BRST] invariant quantities play a crucial role. We prove the nilpotency and absolute anti-commutativity properties of the (anti-) BRST along with (anti-)co-BRST conserved charges within the scope of ACSA to BRST formalism where we take only one Grassmannian variable into account. We also show the (anti-)BRST and (anti-)co-BRST invariances of the Lagrangian within the scope of ACSA.
