Neutrino Direct Simulation Monte Carlo: Accurate modeling of out-of-equilibrium decaying cosmological relics

We consider nonstandard cosmologies in which decaying relics inject energy at MeV temperatures, driving neutrinos out of equilibrium. The subsequent neutrino evolution shapes predictions for the cosmic radiation density and primordial light element abundances. Earlier work introduced Neutrino Direct Simulation Monte Ca...

Rethinking search signatures: Hadronic decays of GeV-scale feebly coupled particles

Experimental searches for GeV-scale feebly interacting particles commonly target the simplest decay signatures with two charged particles, including hadrons. Hadronic modes often dominate the inclusive decay rate, and their simulation relies extensively on \textsc{Pythia}. Its fragmentation model, calibrated mainly on...
