A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spec- trometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to b b final states, and pp collision data at p s = 7 TeV collected with the ATLAS detector at the LHC during 2011

Abstract

A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spec- trometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to b b final states, and pp collision data at p s = 7 TeV collected with the ATLAS detector at the LHC during 2011
