Structure functions in deep inelastic scattering from gauge/string duality beyond single-hadron final states

TL;DR

This paper explores deep inelastic scattering using gauge/string duality, revealing that double-hadron final states dominate at high momentum transfer, extending understanding beyond single-hadron contributions.

Contribution

It introduces the calculation of double-hadron final states in deep inelastic scattering within gauge/string duality, showing their dominance at large momentum transfer.

Findings

Double-hadron states dominate in the Bjorken limit.

Subleading large-Nc contributions are calculable via supergravity.

Results impact the understanding of hadronic structure at strong coupling.

Abstract

We study deep inelastic scattering at large-'t Hooft coupling and finite $x$ from gauge/string duality beyond single-hadron final states which gives the leading large-$N_c$ contribution. Within the supergravity approximation, we calculate the subleading large-$N_c$ contribution by introducing an extra hadron into the final states. We find the contribution from these double-hadron final states will dominate in the Bjorken limit $q^2\rightarrow \infty$ compared with the single-hadron states. We discuss the implications of our results.
