DESCRIPTION:Relaxing the Riemannian condition to incorporate geometric qua
 ntities such as torsion and non-metricity may allow to explore new physics
  associated with defects in a hypothetical space-time microstructure. Here
  we show that non-metricity produces observable effects in quantum fields 
 in the form of 4-fermion contact interactions\, thereby allowing us to con
 strain the scale of non-metricity to be greater than 1 TeV by using result
 s on Bahbah scattering. Our analysis is carried out in the framework of a 
 wide class of theories of gravity in the metric-affine approach. The bound
  obtained represents an improvement of several orders of magnitude to prev
 ious experimental constraints.\n\nhttps://indico.ific.uv.es/event/3207/
