Search for new light scalar bosons produced in association with a bottom-quark and decaying to two tau leptons

A search for new neutral scalar bosons produced in association with a bottom-quark is performed. The analysis uses data acquired with proton-proton collisions at a center-of-mass energy of 8 TeV and observed with the ATLAS detector at the LHC, corresponding to 20.3 fb−1 of integrated luminosity. The search focuses on scalar boson decays into tau lepton pairs, where each decays leptonically (τ → lν ν ̄) resulting in one muon, one electron and four neutrinos. No significant excess is observed and upper limits on the signal strength are determined as a function of scalar boson mass.
