The LZ event with a two-state dark matter halo
Vinicius Oliveira
The LUX-ZEPLIN (LZ) experiment has reported a single nuclear-recoil candidate at keV. LZ interprets it in terms of inelastic dark matter that scatters endothermical…
A Freeze-In Interpretation of the LZ High-Energy Nuclear Recoil Event
D. Cabo-Almeida, F. Costa, D. Feiteira +1
The recent LUX-ZEPLIN (LZ) experiment analysis reported a high energy nuclear recoil candidate at , motivating interpretations in terms of inelastic dark…
Warm fermionic dark matter from freeze-in at stronger coupling
Duarte Feiteira, Vinícius Oliveira
We study warm fermionic dark matter (DM) in the framework of freeze-in at stronger coupling, in the minimal Higgs portal scenario. The reheating temperature is taken to be low, so…
Sterile neutrino dark matter in conformal Majoron models
João Gonçalves, Danny Marfatia, António P. Morais +2
We study sterile neutrino dark matter (DM) in a classically conformal U(1)' extension of the Standard Model with three right-handed neutrinos and a Majoron-like singlet scalar that…
Warm dark matter from freeze-in at stronger coupling
Duarte Feiteira, Oleg Lebedev, Vinícius Oliveira
We study warm Higgs portal dark matter (DM) in the framework of freeze-in at stronger coupling. This scenario assumes that the Standard Model thermal bath temperature has always be…
