Abstract

In this study, we investigate the potential production of a heavy torsion field (TS) at the LHC, which stems from a simplified model rooted in Einstein-Cartan gravity, in connection with dark matter. Within this framework, the torsion field is capable of decaying into pairs of dark matter (DM) particles. Notably, one of these DM particles is heavy enough to decay into dark neutral gauge bosons (A$^{\prime}$) alongside another DM particle. The Analysis has been performed by studying events with dimuon plus missing transverse energy produced in the simulated proton-proton collisions at the Large Hadron Collider, at 13.6 TeV center of mass energy and integrated luminosity of 52 fb$^{-1}$ corresponding to the LHC run 3 circumstances during 2022 and 2023. We provide upper limits, in case no new physics has been discovered, on the masses of various particles in the model as (A$^{\prime}$), as well as the heavy mediator (torsion field).
