Colliding Hadrons as Cosmic Membranes and Possible Signatures of Lost Momentum

TL;DR

This paper explores how high-energy hadron collisions in a TeV-gravity framework can be modeled as cosmic membranes, revealing potential signatures of momentum loss and new decay channels.

Contribution

It introduces the concept of hadrons as cosmic membranes in higher-dimensional spacetime and calculates their effects on gravitational scattering.

Findings

Cosmic membranes influence longitudinal momentum loss in collisions.

Effective hadron membranes modify gravitational scattering corrections.

Potential new decay channels emerge due to cosmic membrane effects.

Abstract

We argue that in the TeV-gravity scenario high energy hadrons colliding on the 3-brane embedded in D=4+n-dimensional spacetime, with n dimensions smaller than the hadron size, can be considered as cosmic membranes. In the 5-dimensional case these cosmic membranes produce effects similar to cosmic strings in the 4-dimensional world. We calculate the corrections to the eikonal approximation for the gravitational scattering of partons due to the presence of effective hadron cosmic membranes. Cosmic membranes dominate the momentum lost in the longitudinal direction for colliding particles that opens new channels for particle decays.
