LEPP Theory Seminar Rashmish Mishra (Harvard)

Physical Sciences Building, Room 401

A model agnostic approach to hidden sectors

In this talk, I will present the theoretical framework to probe hidden sectors that have portal interactions with the standard model mediated by irrelevant operators. The focus is to develop a model-agnostic approach, without any specific model biases. I will focus on hidden sectors with approximate scale symmetry, and elucidate how this allows model-agnostic bounds to be derived. I will present the constraints from the various class of experiments and explain the procedures and assumptions involved. The general picture that emerges is that these sectors are poorly constrained at the moment and points to the kind of future experimental facilities that will improve the reach on such dark sectors. In the second part of the talk, I will discuss the utility of neutrino experiments as probes of such hidden sectors, and their comparable reach to dedicated experiments.
