Missing energy in black hole production and decay at the Large Hadron Collider

TL;DR

This paper explores how black holes produced at the LHC in extra-dimensional models could emit gravitons into the bulk, causing missing energy signatures due to recoil and abrupt Hawking radiation termination.

Contribution

It analyzes the impact of graviton emission on black hole decay signatures, highlighting a novel missing-energy mechanism in TeV-scale gravity scenarios.

Findings

Graviton emission can cause black holes to recoil and leave the brane.

Recoil effects lead to abrupt termination of Hawking radiation.

Large missing-energy signatures are possible at the LHC.

Abstract

Black holes could be produced at the Large Hadron Collider in TeV-scale gravity scenarios. We discuss missing energy mechanisms in black hole production and decay in large extra-dimensional models. In particular, we examine how graviton emission into the bulk could give the black hole enough recoil to leave the brane. Such a perturbation would cause an abrupt termination in Hawking emission and result in large missing-energy signatures.
