Abstract The core-cusp problem persists as an unresolved tension between the pre- dictions of ΛCDM cosmology and observations of dark matter (DM) profiles in dwarf spheroidal and other galaxies. We present a novel scenario for converting cusps into

Abstract By applying copositivity criterion to the scalar potential of the economical $$3-3-1$$ 3-3-1 model, we derive necessary and sufficient bounded-from-below conditions at tree level. Although these are a large number of intricate inequalities f

Heavy neutral leptons (HNL) are SM-gauge-singlet fermions that mix with active neutrinos. We argue that beam-dump and other limits on these mixings $U$ cannot be directly applied to HNLs that interact with a light SM-gauge-singlet scalar $s$ which mi

Heavy neutral leptons (HNLs) are an attractive minimal extension of the Standard Model, as is a singlet scalar $s$ mixing with the Higgs boson. If both are present, it is natural for HNLs to interact with $s$. For a light singlet,the decay $N\to s\nu

We introduce the phenomenology of elliptic flow in nuclear collisions, and argue that its scaling across energies, rapidities and system sizes could be suggestive of a QCD-based rather than a hydrodynamical explanation. As a hypothesis for such an ex
