Systematic decomposition of the neutrinoless double beta decay operator
Florian Bonnet, Martin Hirsch, Toshihiko Ota +1
We discuss the systematic decomposition of the dimension nine neutrinoless double beta decay operator, focusing on mechanisms with potentially small contributions to neutrino mass,…
Supersymmetric type-III seesaw: lepton flavour violation and LHC phenomenology
Martin Hirsch, Werner Porod, Florian Staub +1
We study a supersymmetric version of the seesaw mechanism type-III considering two variants of the model: a minimal version for explaining neutrino data with only two copies of 24-…
Proceedings of the 2nd Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology (FLASY12)
I. de Medeiros Varzielas, C. Hambrock, G. Hiller +66
These are the proceedings of the 2nd Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology, held 30 June 2012 - 4 July 2012, Dortmund, Germany.
Sneutrino Dark Matter in Low-scale Seesaw Scenarios
Valentina De Romeri, Martin Hirsch
We consider supersymmetric models in which sneutrinos are viable dark matter candidates. These are either simple extensions of the Minimal Supersymmetric Standard Model with additi…
Neutrinoless Double Beta Decay and Physics Beyond the Standard Model
Frank F. Deppisch, Martin Hirsch, Heinrich Päs
Neutrinoless double beta decay is the most powerful tool to probe not only for Majorana neutrino masses but for lepton number violating physics in general. We discuss relations bet…
Constrained SUSY seesaws with a 125 GeV Higgs
M. Hirsch, F. R. Joaquim, A. Vicente
Motivated by the ATLAS and CMS discovery of a Higgs-like boson with a mass around 125 GeV, and by the need of explaining neutrino masses, we analyse the three canonical SUSY versio…
Probing neutralino properties in minimal supergravity with bilinear R-parity violation
F. de Campos, O. J. P. Éboli, M. B. Magro +5
Supersymmetric models with bilinear R-parity violation (BRPV) can account for the observed neutrino masses and mixing parameters indicated by neutrino oscillation data. We consider…
Phenomenology of the minimal supersymmetric extension of the standard model
Martin Hirsch, Werner Porod, Laslo Reichert +1
We discuss the minimal supersymmetric extension of the standard model. Gauge couplings unify as in the MSSM, even if the scale of $U(1)_{B-L}\times U(1)_R…
Systematic study of the d=5 Weinberg operator at one-loop order
Florian Bonnet, Martin Hirsch, Toshihiko Ota +1
We perform a systematic study of the Weinberg operator at the one-loop level. We identify three different categories of neutrino mass generation: (1) finite irreducible diagr…
