Heavy neutrinos in particle physics and cosmology
Marco Drewes
Neutrinos are the only particles in the Standard Model of particle physics that have only been observed with left handed chirality to date. If right handed neutrinos exist, they wo…
Sterile neutrino Dark Matter production from scalar decay in a thermal bath
Marco Drewes, Jin U Kang
We calculate the production rate of singlet fermions from the decay of neutral or charged scalar fields in a hot plasma. We find that there are considerable thermal corrections whe…
A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case
Sergey Alekhin, Wolfgang Altmannshofer, Takehiko Asaka +82
This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (Search for Hidden Particles) experiment is intended to hunt for new physics in the larg…
Effective Action for Cosmological Scalar Fields at Finite Temperature
Yeuk-Kwan E. Cheung, Marco Drewes, Jin U Kang +1
Scalar fields appear in many theories beyond the Standard Model of particle physics. In the early universe, they are exposed to extreme conditions, including high temperature and r…
Theoretical Status of Neutrino Physics
Marco Drewes
In the framework of renormalisable relativistic quantum field theory, the explanation of neutrino masses necessarily requires the existence of new physical states. These new states…
Combining Experimental and Cosmological Constraints on Heavy Neutrinos
Marco Drewes, Björn Garbrecht
We study experimental and cosmological constraints on the extension of the Standard Model by three right handed neutrinos with masses between those of the pion and W boson. We comb…
