Light DM Detection 1
- Jeff Dror (Lawrence Berkeley National Laboratory)
In this talk, I will present the theoretical framework to probe dark sectors that have portal interactions with the standard model mediated by irrelevant operators. The focus is to develop a model-independent approach, without any specific model biases. I will focus on dark sectors with approximate conformal dynamics, and elucidate how this allows model-independent bounds to be derived. I will...
In this talk, we discuss the phenomenology of a minimal model for GeV-scale Majorana dark matter (DM) coupled to the standard model lepton sector via a charged scalar singlet. The theoretical framework extends the Standard Model by two $SU(2)_L$ singlets: one charged Higgs boson and a singlet right-handed fermion. The latter plays the role of the DM candidate. We show that there is an...
We propose a new out-of-equilibrium production mechanism of light dark matter: resonance scanning. If the dark matter mass evolved in the early Universe, resonant production may have occurred for a wide range of light dark matter masses today. We show that the dark matter relic abundance may be produced through the Higgs portal, in a manner consistent with current experimental constraints.
Strong bounds from direct detection experiment put stringent
limit on the dark matter mass which forces us to go beyond WIMP model of dark matter. In recent years the light mass dark matter particles gain lots of attention among the particle physicists. In this talk I will discuss about light gauge bosons motivated from U(1) extension of standard model and axions which can be a possible dark...
