Conformal Invariance of the D-Particle Effective Action

TL;DR

This paper demonstrates that the effective action of D-particles exhibits conformal symmetry due to supersymmetry, challenging recent proposals and extending to other Dp-brane systems.

Contribution

It establishes the conformal invariance of D-particle effective actions with field-dependent parameters, contrasting recent generalized conformal symmetry proposals.

Findings

D-particle effective action has conformal symmetry due to supersymmetry

String coupling constant remains unchanged under this symmetry

Conformal symmetry extends to other Dp-brane systems

Abstract

It is shown that the effective theory of D-particles has conformal symmetry with field-dependent parameters. This is a consequence of the supersymmetry. The string coupling constant is not transformed in contrast with the recent proposal of generalized conformal symmtery by Jevicki et al. This conformal symmetry can also be generalized to other Dp-brane systems.
