The measurement of muon momentum by Multiple Coulomb Scattering is a crucial ingredient to the reconstruction of Î½Î¼ 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 â¼ 1 GeV Booster neutrino beam. A sample of â¼ 1000 stopping muons produced by charged current interactions of CNGS Î½Î¼ 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.
