Double beta decay and neutrino mass models
J. C. Helo, M. Hirsch, T. Ota +1
Neutrinoless double beta decay allows to constrain lepton number violating extensions of the standard model. If neutrinos are Majorana particles, the mass mechanism will always con…
Enhancing with the -penguin
M. Hirsch, F. Staub, A. Vicente
Lepton flavor violation (LFV) has been observed in neutrino oscillations. For charged lepton FV decays only upper limits are known, but sizable branching ratios are expected in man…
Hefty MSSM-like light Higgs in extended gauge models
Martin Hirsch, Michal Malinsky, Werner Porod +2
It is well known that in the MSSM the lightest neutral Higgs h^0 must be, at the tree level, lighter than the Z boson and that the loop corrections shift this stringent upper bound…
Soft masses in SUSY SO(10) GUTs with low intermediate scales
Valentina De Romeri, Martin Hirsch, Michal Malinský
The specific shape of the squark, slepton and gaugino mass spectra, if measured with suficient accuracy, can provide invaluable information not only about the dynamics underpinning…
Conservative upper limits on WIMP annihilation cross section from Fermi-LAT γ-rays
Francesca Calore, Valentina De Romeri, Fiorenza Donato
The spectrum of an isotropic extragalactic γ-ray background (EGB) has been measured by the Fermi-LAT telescope at high latitudes. Two new models for the EGB are derived from the su…
Supersymmetric type-III seesaw: lepton flavour violating decays and dark matter
J. N. Esteves, M. Hirsch, W. Porod +2
We study a supersymmetric version of the seesaw mechanism type-III. The model consists of the MSSM particle content plus three copies of 24 superfields. The fermionic part of the S…
