Title: Model independent probe for dark sectors at neutrino experiments

In this talk, I will describe a model independent framework
for constraining an SM-neutral and light dark sector (DS) at neutrino
experiments. This dark sector is coupled to the visible sector via
irrelevant portal interactions. It can be characterized using two energy
scales:  $\Lambda_{UV}$ where the mediator is exchanged and
$\Lambda_{IR}$ which sets the mass of the lightest DS state. The dark
sector dynamics can be described using conformal field theory at
energies given by $\Lambda_{IR}  << E << \Lambda_{UV}$ allowing us to be
model-independent.
