Super D-branes revisited

TL;DR

This paper introduces a super D-brane action with a dynamical tension linked to a worldvolume gauge flux, maintaining symmetry invariance and providing a Hamiltonian formulation in supergravity backgrounds.

Contribution

It presents a novel super D-brane action with dynamical tension and explores its symmetry properties and Hamiltonian form in supergravity backgrounds.

Findings

Tension is a dynamical variable equal to the flux of a p-form gauge field.

The action is invariant under superisometries with appropriate gauge transformations.

Hamiltonian form of the action is derived in general supergravity backgrounds.

Abstract

A version of the kappa-symmetric super D-p-brane action is presented in which the tension is a dynamical variable, equal to the flux of a p-form worldvolume gauge field. The Lagrangian is shown to be invariant under all (super)isometries of the background for appropriate transformations of the worldvolume gauge fields, which determine the central charges in the symmetry algebra. We also present the Hamiltonian form of the action in a general supergravity background.
