Sp(2,R)自对偶的辅助张量场

Auxiliary tensor fields for Sp(2,R) self-duality

Evgeny A. Ivanov, Olaf Lechtenfeld, Boris M. Zupnik

摘要:

陪集Sp(2,R)/U(1)由两个实标量场参数化。本文将阿贝尔规范场的U(1)自对偶非线性模型中的辅助张量(bispinor)场的形式推广到Sp(2,R)自对偶的情形。在这个新的表述中,非线性标量规范运动方程的Sp(2,R)对偶性等价于辅助相互作用的Sp(2,R)不变性。我们用两种不同的方法导出了这个结果,旨在进一步将其应用于超对称理论。我们还考虑了与更高的衍生物的相互作用的扩展。

英文摘要:

The coset Sp(2,R)/U(1) is parametrized by two real scalar fields. We generalize the formalism of auxiliary tensor (bispinor) fields in U(1) self-dual nonlinear models of abelian gauge fields to the case of Sp(2,R) self-duality. In this new formulation, Sp(2,R) duality of the nonlinear scalar-gauge equations of motion is equivalent to an Sp(2,R) invariance of the auxiliary interaction. We derive this result in two different ways, aiming at its further application to supersymmetric theories. We also consider an extension to interactions with higher derivatives.
