Are there interesting implications one can test at LHCb? __Leader__: ???, __other members__: ??? * In composite Higgs models with a additional leptoquark pseudo NGB, what level of LVF signals are possible by increasing the lepton partial compositeness (assuming some protection for mu to e gamma)? __Leader__: Marco Nardecchia, __other members__: Cedric Delaunay, Alberto Parolini, Florian Goertz, Adrian Carmona, M.Frigerio, A.Bharucha * Generalizing the composite framework, we consider both left- and right-handed currents in the lepton sector, but restrict ourselves to new left-handed quark contributions. This can be motivated by the large top-quark mass, which (in a class of models) also leads to a large b_L compositeness, while the right-handed bottom would be rather elementary. * We thus consider the operators: ... * Since the constraints in the up-type sector are less stringent, we focus on the down sector, {{:2015:groups:np:photo46858256864356766.jpg?200|}} Please add your name to the above lists if you're interested to take part in the discussions.
