Accidental permutation symmetries as a test for Grand Unification: the supersymmetric case
Sylvain Fichet, Björn Herrmann
Unification of matter fields implies the existence of accidental permutation symmetries, which potentially remain immune to large quantum corrections up to the TeV scale. We invest…
The Global Higgs as a Signal for Compositeness at the LHC
Sylvain Fichet, Gero von Gersdorff, Eduardo Ponton +1
The radial excitation of the global symmetry-breaking vacuum in composite Higgs models, called the "global Higgs", has been recently a focus of investigation. In this paper we stud…
New likelihoods for shape analysis
Sylvain Fichet
We introduce a new kind of likelihood function based on the sequence of moments of the data distribution. Both binned and unbinned data samples are discussed, and the multivariate…
Les Houches 2013: Physics at TeV Colliders: New Physics Working Group Report
G. Brooijmans, R. Contino, B. Fuks +87
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 3--21 June, 2013). Our report includes new computatio…
A new flavour imprint of SU(5)-like Grand Unification and its LHC signatures
Sylvain Fichet, Björn Herrmann, Yannick Stoll
We point out that the hypothesis of a SU(5)-like supersymmetric Grand Unified Theory (GUT) implies a generic relation within the flavour structure of up-type squarks. Contrary to o…
Mixed sneutrino dark matter in light of the 2011 XENON and LHC results
Beranger Dumont, Genevieve Belanger, Sylvain Fichet +2
In the context of supersymmetric models in which small Dirac neutrino masses are generated by supersymmetry breaking, a mainly right-handed (RH) mixed sneutrino can be an excellent…
