The measurement of muon momentum by Multiple Coulomb Scattering is a crucial ingredient to the reconstruction of nu(mu) CC events in the ICARUS-T600 liquid argon TPC in absence of magnetic field, as in the search for sterile neutrinos at Fermilab where ICARUS will be exposed to similar to 1 GeV Booster neutrino beam. A sample of similar to 1000 stopping muons produced by charged current interactions of CNGS nu(mu) in the surrounding rock at the INFN Gran Sasso underground Laboratory provides an ideal benchmark in the few-GeV range since their momentum can be directly and independently obtained by the calorimetric measurement.

Abstract
The measurement of muon momentum by Multiple Coulomb Scattering is a crucial ingredient to the reconstruction of nu(mu) CC events in the ICARUS-T600 liquid argon TPC in absence of magnetic field, as in the search for sterile neutrinos at Fermilab where ICARUS will be exposed to similar to 1 GeV Booster neutrino beam. A sample of similar to 1000 stopping muons produced by charged current interactions of CNGS nu(mu) in the surrounding rock at the INFN Gran Sasso underground Laboratory provides an ideal benchmark in the few-GeV range since their momentum can be directly and independently obtained by the calorimetric measurement. Stopping muon momentum in the 0.5-4.5 GeV/c range has been reconstructed via Multiple Coulomb Scattering with resolution ranging from 10 to 25% depending on muon energy, track length and uniformity of the electric field in the drift volume.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
