Scattering Light by Light at 750 GeV at the LHC
Sylvain Fichet, Gero von Gersdorff, Christophe Royon
We consider the possibility that the diphoton excess at 750 GeV is caused by a new scalar resonance produced in photon fusion. This scenario is parametrised by only one relevant ef…
Prospects for new physics searches at the LHC in the forward proton mode
Sylvain Fichet
The installation of forward proton detectors at the LHC will provide the possibility to observe central exclusive processes, opening a novel window on physics beyond the Standard M…
Relating LHC event rates to supersymmetric Grand Unified Theories containing
Björn Herrmann, Sylvain Fichet, Yannick Stoll
We elaborate on a recently found relation confined to the up-(s)quark flavour space, that remains immune to large quantum corrections up to the TeV scale. We investigate th…
Anatomy of the Higgs fits: a first guide to statistical treatments of the theoretical uncertainties
Sylvain Fichet, Grégory Moreau
The studies of the Higgs boson couplings based on the recent and upcoming LHC data open up a new window on physics beyond the Standard Model. In this paper, we propose a statistica…
Effective theory for neutral resonances and a statistical dissection of the ATLAS diboson excess
Sylvain Fichet, Gero von Gersdorff
We classify the complete set of dimension-5 operators relevant for the resonant production of a singlet of spin 0 or 2 linearly coupled to the Standard Model (SM). We compute the d…
Anomalous light-by-light scattering at the LHC: recent developments and future perspectives
Sylvain Fichet
The installation of forward proton detectors at the LHC will provide the possibility to perform new high-precision measurements, opening a novel window on physics beyond the Standa…
