Abstract

We study TT¯-like deformations of d>2 Yang-Mills theories. The standard TT¯ flows lead to multitrace Lagrangians, and the non-Abelian gauge structures make it challenging to find Lagrangians in a closed form. However, within the geometric approach to TT¯, we obtain the closed-form solution to the metric flow and stress-energy tensor, and show that instanton solutions are undeformed. We also introduce new symmetrized single-trace TT¯-like deformations, whose solutions in d=4 include the non-Abelian Born-Infeld Lagrangian proposed by Tseytlin in 1997.

杨-米尔斯理论的流动
我们研究了d>;2 Yang-Mills理论的类TT¯变形。标准的TT¯流导致了多迹拉格朗日量,而非阿贝尔规范结构使得寻找封闭形式的拉格朗日量变得困难。然而,在TT¯的几何方法中,我们得到了度量流量和应力-能量张量的封闭解,并表明瞬时解是不变形的。我们还引入了新的对称单迹类TT¯变形,其在d=4中的解包括Tseytlin(1997)提出的非阿贝尔Born-Infeld拉格朗日。2025年由美国物理学会出版
