On the search of sterile neutrinos by oscillometry measurements

Abstract

It is shown that the "new" neutrino with a high mass squared difference and a small mixing angle should reveal itself in the oscillometry measurements. For a judicious monochromatic neutrino source the "new" oscillation length $L_{42}$ is expected shorter than 1.5 m. Thus the needed measurements can be implemented with a gaseous spherical TPC of modest dimensions with a very good energy and position resolution. The best candidates for oscillometry are discussed and the sensitivity to the mixing angle ${\theta }_{14}$ has been estimated: ${\sin }^2(2{\theta }_{14})$=0.05 (99{%}) for two months of data handling with ${}^{51}$Cr.
