Dynamical flavor origin of symmetries
D. Aristizabal Sierra, Mikael Dhen, Chee Sheng Fong +1
Discrete Abelian symmetries () are a common "artifact" of beyond the standard model physics models. They provide different avenues for constructing consistent scenari…
Higgs in Abelian and Non-Abelian Flavor Symmetry Models
Julian Heeck, Martin Holthausen, Werner Rodejohann +1
We study lepton flavor violating Higgs decays in two models, with the recently found hint for Higgs at CMS as a benchmark value for the branching ratio. The first model us…
Disappearing charged tracks in association with displaced leptons from supersymmetry
Christoffer Petersson
In this note we discuss a characteristic collider signature of models of gauge mediated supersymmetry breaking in which the selectron and smuon are mass-degenerate co-NLSP. In thes…
LHC Tests of Light Neutralino Dark Matter without Light Sfermions
Lorenzo Calibbi, Jonas M. Lindert, Toshihiko Ota +1
We address the question how light the lightest MSSM neutralino can be as dark matter candidate in a scenario where all supersymmetric scalar particles are heavy. The hypothesis tha…
Fermion Masses from Six Dimensions and Implications for Majorana Neutrinos
J-M Frère, M Libanov, S Mollet +1
In these notes, we review the main results of our approach to fermion masses. The marge mass ratios between fermions, confronted with a unique breaking mechanism leading to vector…
Lepton Flavor Violation in Flavored Gauge Mediation
Lorenzo Calibbi, Paride Paradisi, Robert Ziegler
We study the anatomy and phenomenology of Lepton Flavor Violation (LFV) in the context of Flavored Gauge Mediation (FGM). Within FGM, the messenger sector couples directly to the M…
What is a Natural SUSY scenario?
J. Alberto Casas, Jesus M. Moreno, Sandra Robles +2
The idea of "Natural SUSY", understood as a supersymmetric scenario where the fine-tuning is as mild as possible, is a reasonable guide to explore supersymmetric phenomenology. In…
Bremsstrahlung and Gamma Ray Lines in 3 Scenarios of Dark Matter Annihilation
Federica Giacchino, Laura Lopez-Honorez, Michel H. G. Tytgat
Gamma ray spectral features are of interest for indirect searches of dark matter (DM). Following Barger et al, we consider 3 simple scenarios of DM that annihilates into Standard M…
Selectron NLSP in Gauge Mediation
Lorenzo Calibbi, Alberto Mariotti, Christoffer Petersson +1
We discuss gauge mediation models in which the smuon and the selectron are mass-degenerate co-NLSP, which we, for brevity, refer to as selectron NLSP. In these models, the stau, as…
Can a millicharged dark matter particle emit an observable gamma-ray line?
Chaïmae El Aisati, Thomas Hambye, Tiziana Scarna
If a gamma-ray line is observed in the near future, it will be important to determine what kind of dark matter (DM) particle could be at its origin. We investigate the possibility…
CP violation from pure gauge in extra dimensions
Jean-Marie Frère, Maxim Libanov, Simon Mollet
One of the Sakharov's condition for baryogenesis is the violation of both C and CP. In the Standard Model, gauge interactions break maximally C, but CP is only broken through the Y…
Invisible Z' and dark matter: LHC vs LUX constraints
Giorgio Arcadi, Yann Mambrini, Michel H. G. Tytgat +1
We consider a simple, yet generic scenario in which a new heavy gauge boson couples both to SM fermions and to dark matter. In this framework we confront the best LHC limits o…
Radiative neutrino mass generation linked to neutrino mixing and -decay predictions
Michael Gustafsson, Jose M. No, Maximiliano A. Rivera
We discuss the connection between the origin of neutrino masses and their mixings which arises in a class of scenarios with radiatively induced neutrino masses. In these scenarios,…
Scalar triplet flavored leptogenesis: a systematic approach
D. Aristizabal Sierra, Mikael Dhen, Thomas Hambye
Type-II seesaw is a simple scenario in which Majorana neutrino masses are generated by the exchange of a heavy scalar electroweak triplet. When endowed with additional heavy fields…
