Název v původním jazyce

A measurement of material in the ATLAS tracker using secondary hadronic interactions in 7 TeV pp collisions

Popis výsledku v původním jazyce

Knowledge of the material in the ATLAS inner tracking detector is crucial in understanding the reconstruction of charged-particle tracks, the performance of algorithms that identify jets containing b-hadrons and is also essential to reduce background in searches for exotic particles that can decay within the inner detector volume. Interactions of primary hadrons produced in pp collisions with the material in the inner detector are used to map the location and amount of this material. The hadronic interactions of primary particles may result in secondary vertices, which in this analysis are reconstructed by an inclusive vertex-finding algorithm. Data were collected using minimum-bias triggers by the ATLAS detector operating at the LHC during 2010 at centre-of-mass energy s = 7 TeV, and correspond to an integrated luminosity of 19 nb()(1). Kinematic properties of these secondary vertices are used to study the validity of the modelling of hadronic interactions in simulation.nn
