Abstract
We study the potential of the combination of the golden (νeâνμ) and silver (νeâνÏ) channels to solve the octant degeneracy affecting the measurement of θ13 and δ at future neutrino factories. To search for Ï leptons produced in Î½Ï charged-current interactions, we consider two different detectors: the Emulsion Cloud Chamber detector (ECC) and the Liquid Argon Time Projection Chamber (LAr TPC). We show that, when using similar detector masses, the upgraded version of the ECC detector (sensitive also to hadronic Ï decay modes) and the LAr TPC detector have comparable sensitivities to the octant of θ23, being able to discriminate the two solutions for sin2(2θ13)â³10â3 at 3Ï level if θ23=40°. We also show that the same setups are able to see deviation from maximal mixing as small as â¼ (4-6)% (at 3Ï) if θ13 is close to its upper bound.
