Large angular momentum closed strings colliding with D-branes

TL;DR

This paper studies the interactions of high-angular-momentum closed strings with D-branes using conformal field theory, confirming a correspondence with boundary gauge theory operators.

Contribution

It provides explicit CFT calculations for complex closed string states and supports the gauge/string duality conjecture for large angular momentum states.

Findings

Explicit CFT results match the gauge theory correspondence.

Validates the large angular momentum limit in string-D-brane interactions.

Supports the AdS/CFT correspondence for specific string states.

Abstract

We investigate colliding processes of closed strings with large angular momenta with D-branes. We give explicit CFT calculations for closed string states with an arbitrary number of bosonic excitations and no or one fermion excitation. The results reproduce the correspondence between closed string states and single trace operators in the boundary gauge theory recently suggested by Berenstein, Maldacena and Nastase.
