Abstract

LHC provides a excellent laboratory to probe massive gravitons effects in scenarios with low scale gravity up to several Tev. Based on this fact, in the present work we are interested in analyzing the possible constraints on the free parameters of the gravity Lagrangian in 4 dimensions recently studied in the reference [1] taking only the torsion effects into account, in order to generate mass for the graviton. We shall consider a effective fields theory approach, in which the gravity is excited by the torsion but not the metric.
