DOI: 10.1007/jhep08(2017)053
Abstract: A bstractWe explore the anomaly-cancellation constraints on simplified dark matter (DM) models with an extra U(1)′ gauge boson Z′. We show that, if the Standard Model (SM) fermions are supplemented by a single DM fermion… read more here.

DOI: 10.1016/j.nuclphysb.2021.115441
Abstract: Abstract The principle of multiple point criticality (PMPC), which allowed the prediction of the Higgs boson mass before its discovery, has so far been applied to radiatively generated vacua. If this principle is fundamental, following… read more here.

DOI: 10.1088/1674-1137/abc244
Abstract: We present a dark matter model to explain the excess events in the electron recoil data recently reported by the Xenon1T experiment. In our model, dark matter annihilates into a pair of on-shell particles ,… read more here.

DOI: 10.1088/1742-5468/aad6b5
Abstract: We derive hydrodynamic equations from Vicsek-style dry active matter models in three dimensions (3D), building on our experience on the 2D case using the Boltzmann-Ginzburg-Landau approach. The hydrodynamic equations are obtained from a Boltzmann equation… read more here.

DOI: 10.1093/mnras/staa1768
Abstract: The nature of dark matter sets the timeline for the formation of first collapsed halos and thus affects the sources of reionization. Here, we consider two different models of dark matter: cold dark matter (CDM)… read more here.
