We investigate the interactions of a light scalar with the Higgs boson and second-generation fermions, which trigger new rare decays of the Higgs boson into 4μ, 2μ2γ , 6μ and 4μ2 j. We recast current LHC searches to constrain these decays and develop... Read More about New Higgs decays to axion-like particles.

We constrain CP-violating charged and neutral anomalous triple gauge couplings using LHC measurements and projections of diboson and VBF Vjj production, both with subsequent leptonic decays. For triple gauge couplings involving W bosons we analyse di... Read More about Constraining CP violating operators in charged and neutral triple gauge couplings.
