Searches for hidden sectors using $K^{+} \to I ¨ ^{+} X$ decays

NA62 Collaboration

Results from the study of the rare decays $K^{+} \to I ¨ ^{+} I^½ I^ˉ ½$ , $K^{+} \to I ¨ ^{+} I^¼^{+} I^¼^{-}$ and $K^{+} \to I ¨ ^{+} I^^{3} I^^{3}$ at the NA62 experiment at CERN are interpreted…

Minimal effective theory for leptogenesis, dark matter, and neutrino masses

Tomas Blazek, Peter Matak, Jan Ramaj +1

We study the phenomenology of choosing a minimal set of effective operators simultaneously generating the dark matter relic density and matter-antimatter asymmetry of the universe.…

Asymmetric dark matter from semi-annihilation: unitarity constraints and long-lived final states

TomÃ¡Å¡ BlaÅ¾ek, Peter MatÃ¡k, Viktor Zaujec

This work presents an asymmetric dark matter model with relic density determined by the freeze-out of asymmetric semi-annihilations into long-lived particles slowly decaying into t…
