The Four Basic Ways of Creating Dark Matter Through a Portal
Xiaoyong Chu, Thomas Hambye, Michel H. G. Tytgat
We consider the possibility that along the thermal history of the Universe, dark matter (DM) would have been created from Standard Model particles, either through a kinetic mixing…
Relations among neutrino observables in the light of a large theta_13 angle
Xiaoyong Chu, Mikael Dhen, Thomas Hambye
The recent T2K and MINOS indications for a "large" theta_13 neutrino mixing angle can be accommodated in principle by an infinite number of Yukawa flavour structures in the seesaw…
Sub-GeV dark matter as pseudo-Goldstone from the seesaw scale
Michele Frigerio, Thomas Hambye, Eduard Masso
Pseudo Nambu-Goldstone bosons (pNGBs) are naturally light spin-zero particles, which can be interesting dark matter (DM) candidates. We study the phenomenology of a pNGB theta asso…
