D-brane Thickness

TL;DR

This paper explores the concept of scale in D-brane theory, analyzing how scattering processes between D-branes can reveal conditions for surpassing the fundamental string length scale.

Contribution

It provides a new perspective on D-brane scale by examining scattering phenomena, offering insights into the effective size of D-branes beyond the string scale.

Findings

Scattering of D4-brane by D0-brane indicates conditions to exceed string scale.

Different viewpoints on D-brane scale are discussed.

The study links scattering behavior to D-brane thickness.

Abstract

The scale in the D-brane theory is discussed from different points of view. It is shown that scattering of a $D_4$-brane by a $D_0$-brane gives the condition to penetrate beyond the string scale.
