Track finding and identification of converted photons

A method for reconstructing e+e- pair tracks originating from converted photons is described.Reconstruction efficiency and vertex properties are evaluated and discussed in detail in single-photon samples.Results from applying the reconstruction method to H->gamma gamma decays in low luminosity pi...

Sumario:A method for reconstructing e+e- pair tracks originating from converted photons is described.Reconstruction efficiency and vertex properties are evaluated and discussed in detail in single-photon samples.Results from applying the reconstruction method to H->gamma gamma decays in low luminosity pile-up regime and related fake rate are also shown.
