DOI: 10.1007/jhep12(2018)092
Abstract: A bstractWe examine the sensitivity at a future 100 TeV proton-proton collider to compressed dark sectors whose decay products are invisible due to below-threshold energies and/or small couplings to the Standard Model. Such a scenario… read more here.

DOI: 10.1093/mnras/stae2712
Abstract: We do a careful investigation of the prospects of dark energy (DE) interacting with cold dark matter (CDM) in alleviating the S8 clustering tension. To this end, we consider various well-known parametrizations of the DE… read more here.

DOI: 10.1103/physrevd.100.075017
Abstract: We examine the sensitivity of electric dipole moments (EDMs) to new $CP$-violating physics in a hidden (or dark) sector, neutral under the Standard Model (SM) gauge groups, and coupled via renormalizable portals. In the absence… read more here.

DOI: 10.1103/physrevd.102.023535
Abstract: We investigate generalized interacting dark matter--dark energy scenarios with a time-dependent coupling parameter, allowing also for freedom in the neutrino sector. The models are tested in the phantom and quintessence regimes, characterized by equations of… read more here.

DOI: 10.1103/physrevd.110.075030
Abstract: The nature of dark matter remains one of the greatest unsolved mysteries in elementary particle physics. It might well be that the dark matter particle belongs to a dark sector completely secluded or extremely weakly… read more here.

DOI: 10.1103/physrevlett.129.021302
Abstract: Dark sectors provide a compelling theoretical framework for thermally producing sub-GeV dark matter, and motivate an expansive new accelerator and direct-detection experimental program. We demonstrate the power of constraining such dark sectors using the measured… read more here.
