Superstrings with the Galileon Measure

TL;DR

This paper explores a novel superstring theory formulation using a Galileon-invariant measure, deriving the supersymmetric action and tension from equations of motion, potentially addressing unresolved issues in string theory.

Contribution

It introduces a superstring model with a Galileon measure invariant under Galileon shift symmetry, deriving all terms from equations of motion.

Findings

Supersymmetric action includes all terms derived from equations of motion.

The vacuum translation invariance is maintained up to Galileon transformations.

The model offers a new approach to superstring theory with modified measures.

Abstract

The modified measure theories recommend themselves as a good possibility to go beyond the standard formulation to solve yet unsolved problems. The Galileon measure that is constructed in the way to be invariant under the Galileon shift symmetry is considered in the context of superstring theory. The translation invariance of the vacuum holds up to a Galileon transformations. The supersymmetric action is presented with all terms, including the tension, being derived from the equations of motion.
