Composite leptoquarks and anomalies in -meson decays
Ben Gripaios, Marco Nardecchia, S. A. Renner
We attempt to explain recent anomalies in semileptonic decays at LHCb via a composite Higgs model, in which both the Higgs and an -triplet leptoquark arise as pseudo-G…
Hint of Lepton Flavour Non-Universality in Meson Decays
Diptimoy Ghosh, Marco Nardecchia, S. A. Renner
The LHCb collaboration has recently presented their result on R_K = BR(B+ -> K+ mu+ mu-)/ BR(B+ -> K+ e+ e-) for the dilepton invariant mass bin m_{ll}^2 = 1-6 GeV^2 (l = mu, e). T…
Flavor and CP violation in Higgs decays
Joachim Kopp, Marco Nardecchia
Flavor violating interactions of the Higgs boson are a generic feature of models with extended electroweak symmetry breaking sectors. Here, we investigate CP violation in these int…
Constraining new coloured matter from the ratio of 3- to 2-jets cross sections at the LHC
Diego Becciolini, Marc Gillioz, Marco Nardecchia +2
The Large Hadron Collider experiments are probing the evolution of the strong coupling up to the TeV scale. We show how the ratio of 3- to 2-jets cross sections is affected b…
