The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

The Majorana nature of neutrinos can be experimentally verified only via lepton-number
violating processes involving charged leptons. We study 36 lepton-number violating (LV) …

We consider the possibility to detect right-handed neutrinos, which are mostly singlets of the
standard model gauge group, at future accelerators. Substantial mixing of these neutrinos …

While all models of Majorana neutrino masses lead to the same dimension five effective
operator, which does not conserve lepton number, the dimension six operators induced at …

We investigate the LHC discovery potential for electroweak scale heavy neutrino singlets
(seesaw I), scalar triplets (seesaw II) and fermion triplets (seesaw III). For seesaw I we …

We demonstrate how to systematically test a well-motivated mechanism for neutrino mass
generation (Type-II seesaw) at the LHC, in which a Higgs triplet is introduced. In the …

We introduce the topic of dynamical breaking of the electroweak symmetry and its link to
unparticle physics and cosmology. The knowledge of the phase diagram of strongly coupled …

The focus of this paper lies on the possible experimental tests of leptogenesis scenarios. We
consider both leptogenesis generated from oscillations, as well as leptogenesis from out-of …

Neutrino masses can be generated by fermion triplets with TeV-scale mass, that would
manifest at LHC as production of two leptons together with two heavy standard model (SM) …

The possible discovery of proton decay, neutron–antineutron oscillation, neutrinoless
double beta decay in low energy experiments, and exotic signals related to the violation of …
