Polyakov D1 Brane Action On the Light-Front

TL;DR

This paper analyzes the quantization of the conformally gauge-fixed Polyakov D1 brane action on the light-front, revealing it as a constrained system and applying Dirac's method for quantization.

Contribution

It demonstrates the constrained nature of the Polyakov D1 brane action on the light-front and applies standard constraint quantization techniques in this context.

Findings

The model is identified as a constrained system on the light-front.

Standard Dirac constraint quantization techniques are successfully applied.

The approach contrasts with instant-form analysis of the same model.

Abstract

Conformally gauge-fixed Polyakov D1 brane action is seen to be a constrained sys tem in the sense of Dirac when it is considered on the light-front in contrast t o the case when it is consdired in the instant-form. The model is quantized usin g the standard constraint quantization techniques on the light-front.
