The two-neutrino force and where to find it

ORAL

Abstract

The Standard Model predicts a long-range force, proportional to $G_F^2/r^5$, between fermions due to the exchange of a pair of neutrinos. Furthermore, this is the largest parity-violating long-range force in the Standard Model. However, this quantum force is feeble and has not been observed yet. In this talk, I will present the neutrino force and discuss possible probes of this force. I will talk about scenarios where the effects due to the neutrino force can be enhanced, thereby providing sensitivity to neutrino physics parameters that have so far eluded us.
