A Covariant Action for the Eleven Dimensional Superstring

TL;DR

This paper proposes a covariant, super Poincaré invariant action for the eleven-dimensional superstring, demonstrating free dynamics in the physical variable sector, advancing the theoretical framework of superstring models.

Contribution

It introduces a novel covariant action for the 11D superstring that maintains super Poincaré invariance and exhibits free dynamics in physical variables.

Findings

The action is super Poincaré invariant.

Physical variables exhibit free dynamics.

The model advances superstring theory in eleven dimensions.

Abstract

We suggest a super Poincar\'e invariant action for closed eleven dimensional superstring. The sector of physical variables $x^i$, $\theta_a$, $\bar\theta_{\dot a}$, with $a,\dot a=1...8$ and $x^i$ the transverse part of the D=11 $x^\mu$ coordinate is shown to possess free dynamics.
