Sterile Neutrino Dark Matter Cries for GeV Heavy Neutral Leptons

Marco Drewes, Yannis Georis, Juraj Klarić +2

The ordinary and dark matter in the Universe may share a common origin in the framework of a minimal extension of the Standard Model by three right-handed neutrinos. A pair of such…

Sterile Neutrino Dark Matter, Matter-Antimatter Separation, and the QCD Phase Transition

Mikhail Shaposhnikov, Alexei Yu Smirnov

The Universe may contain sufficiently small size matter-antimatter domains at temperatures of a few hundred MeV, without violating the success of Big Bang Nucleosynthesis. We demon…

Scale invariant Einstein-Cartan gravity and flat space conformal symmetry

Georgios K. Karananas, Mikhail Shaposhnikov, Sebastian Zell

We find the conditions under which scale-invariant Einstein-Cartan gravity with scalar matter fields leads to an approximate conformal invariance of the flat space particle theory…

Observation of collider muon neutrinos with the SND@LHC experiment

LHC Collaboration

We report the direct observation of muon neutrino interactions with the SND@LHC detector at the Large Hadron Collider. A data set of proton-proton collisions at …

The Present and Future Status of Heavy Neutral Leptons

Asli M. Abdullahi, Pablo Barham Alzas, Brian Batell +42

The existence of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillat…

Field redefinitions, perturbative unitarity and Higgs inflation

Georgios K. Karananas, Mikhail Shaposhnikov, Sebastian Zell

For inflation driven by the Higgs field coupled non-minimally to gravity, we study the cutoff energy scale above which perturbation theory breaks down. Employing the metric formula…
