Constraints on Complex Electroweak WIMPs from Solar Capture
Juan P. Luengas, Maxim Pospelov, Harikrishnan Ramani
One of the most convincing realizations of particle dark matter is provided by models based on electroweak multiplets. The lightest neutral state of such a multiplet can be a stabl…
Strong Constraints on Higgsino Dark Matter from Solar Capture
Maxim Pospelov, Harikrishnan Ramani
Higgsino dark matter remains one of the most convincing dark matter candidates. It can exist in a ``quasi-Dirac" regime, when the splitting between two Majorana components is on th…
Signatures of gravity-mediated dark matter interaction in theories with large extra dimensions
A. Clarke, V. V. Flambaum, M. Pospelov +1
Dark matter particles that couple to the Standard Model only through gravity are usually regarded as inaccessible to laboratory detection. This expectation can change in theories w…
New physics in multi-lepton tau decays
Yohei Ema, Patrick J. Fox, Matheus Hostert +4
Dark particles with lepton-flavor-violating couplings to the tau lepton can induce rare neutrinoless decays with large final state multiplicities. We study models where transit…
Freeze-in dark matter in neutron stars
Maxim Pospelov, Samya Roychowdhury
Every neutron star is born in the process of core-collapse supernova explosion that, for a brief moment, reproduces conditions of the early Universe with temperatures $T\sim O(30\r…
Novel Constraints on Spin-Dependent Light Dark Matter Scattering
Alexander Clarke, Maxim Pospelov
We explore the sensitivity of the SNO experiment to light dark matter particles with spin-dependent interactions with nucleons. We show that the pair-production of MeV scale da…
