Heavy neutrino searches at the LHC with displaced vertices
Juan Helo, Martin Hirsch, Sergey Kovalenko
Sterile neutrinos with masses in the range (1-100) GeV, have been searched for in a variety of experiments. Here, we discuss the prospects to search for sterile neutrinos at the LH…
Falsifying High-Scale Leptogenesis at the LHC
Frank F. Deppisch, Julia Harz, Martin Hirsch
Measuring a non-zero value for the cross section of any lepton number violating (LNV) process would put a strong lower limit on the washout factor for the effective lepton number d…
LHC-scale left-right symmetry and unification
Carolina Arbeláez, Martin Hirsch, Michal Malinský +1
We construct a comprehensive list of non-supersymmetric standard model extensions with a low-scale LR-symmetric intermediate stage that may be obtained as simple low-energy effecti…
WIMP dark matter as radiative neutrino mass messenger
M. Hirsch, R. A. Lineros, S. Morisi +3
The minimal seesaw extension of the Standard SU(3) x SU(2) x U(1) Model requires two electroweak singlet fermions in order to accommodate the neutrino oscillation parameters at tre…
Supersymmetric SO(10) GUTs with sliding scales
C. Arbelaez, R. M. Fonseca, M. Hirsch +1
We construct lists of supersymmetric models with extended gauge groups at intermediate steps, all of which are based on SO(10) unification. We consider three different kinds of set…
