Abstract
- We present the results of global analyses of short-baseline neutrino oscillation data in 3 + 1, 3 + 2 and 3+1 + 1 neutrino mixing schemes. We show that the data do not allow us to abandon the simplest 3 + 1 scheme in favor of the more complex 3 + 2 and 3 + 1 + 1 schemes. We present the allowed region in the 3 + 1 parameter space, which is located at Δm41² between 0.82 and 2.19 eV² at 3s. The case of no oscillations is disfavored by about 6s, which decreases dramatically to about 2s if the Liquid Scintillating Neutrino Detector (LSND) data are not considered. Hence, new high-precision experiments are needed to check the LSND signal. [ABSTRACT FROM AUTHOR]
