Contribution

It proposes a novel detection method for string resonances at the LHC using event shape variables and kinematic observables to distinguish signals from background.

Findings

String resonances produce distinctive signatures in photon+jet events.

Event shape variables help discriminate string signals from Standard Model background.

Abstract

The Large Hadron Collider promises to discover new physics beyond the Standard Model. An exciting possibility is the formation of string resonances at the TeV scale. In this article, we show how string resonances may be detected at the LHC in the $pp\to\gamma+jet$ channel. Our study is based on event shape variables, missing energy and momentum, maximum transverse momentum of photons and dijet invariant mass. These observables provide interesting signatures which enable us to discriminate string events from the Standard Model background.
