Unveiling the Randall-Sundrum graviton: Exploring kinematic signatures at the LHC

Abstract

Since Kaluza-Klein's pioneering work in proposing a five-dimensional spacetime, numerous theories have emerged positing the existence of extra dimensions (EDs) beyond the known (3+1)-spacetime framework. Notable among these theories is the Randall-Sundrum (RS) model which involves warped non-compact EDs where only the graviton can propagate. This study compares kinematic variable distributions of various RS production processes involving its hypothetical graviton at the Large Hadron Collider (LHC) with the objective of discerning any distinctive trends based on its functional role: whether as a final state, a propagator, or a constituent of a trijet. We find that the RS Graviton jets show the same trends regardless of the graviton's role.
