Experimental constraints on lepton mixing angles and neutrino mass differences for three simultaneously oscillating neutrino flavours

Abstract An analysis of experimental results in the framework of simultaneous oscillations of three neutrino flavours is used, in a combined fit, to constrain the elements of the 3 × 3 unitary lepton mixing matrix and to obtain limits on the three lepton mixing angles α e μ , α e τ and α μτ .
