Abstract

It is well known that inclusion of torsion in the gravitational formalism, leads to four-fermion interactions. Although the coupling constant of this interaction is strongly suppressed in four dimensions, its value is enhanced in models with nn extra dimensions. In this context, we reinterpret the recent limits established by LHC experiments to four-fermion contact interactions, to set bounds on the size of the extra dimensions. For n=2n=2, the limits are comparable to those in the literature, while for n3n\ge 3 the volume of the extra dimensions is strongly constrained.
