Manifestly SL(2, R) Duality-Symmetric Forms in ModMax Theory

Abstract

A bstract In this paper, we will investigate a manifestly SL(2, R )-invariant structure for the energy-momentum tensor of ModMax theory as a nonlinear modification of Maxwell electrodynamics which includes conformal invariance as well. In the context of this theory, we show that the energy-momentum tensor of the generalized Born-Infeld theory can also be written in the same invariant form. We will find manifestly duality-invariant parts of the actions corresponding to the invariant couplings λ and γ in these theories. It can be shown that the resultant actions correspond to the irrelevant and marginal $$ T\overline{T} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>T</mml:mi> <mml:mover> <mml:mi>T</mml:mi> <mml:mo>¯</mml:mo> </mml:mover> </mml:math> -like deformations, respectively.
