Description
Light dark matter(1 − 30 MeV) particles which can be pair
produced in electron-positron annihilation e − e + → χ χ inside the
supernova SN1987A core, take away the energy released in the supernova
SN1987A explosion. Working within the framework of q-deformed scenario
(non-equilibrium statistics) and using the Raffelt’s criteria on the
energy loss rate and the optical depth criteria on the free streaming
of the dark matter fermion, we find that the lower bound on the scale
Λ of the dark matter effective theory to be Λ ∼1.0E+07 TeV for m χ =
30 MeV. We will briefly address our recent work on the supernova and relic density constraints on leptophillic operators.
