Abstract:
Neutrino oscillation occurs if neutrinos have masses and if they mix among each other. this phenomenon would be in close analogy to the experimentally observed mixing in quark sector. Neutrino oscillations are therefore very interesting in the context of elementary particle physics. Neutrino oscillation in matter is probably the reason for the observed deficit of solar neutrino flux .the search for neutrino oscillation is the only way to investigate even for very small difference of neutrino masses. the evidence of small but non vanishing neutrino masses represent one of the few clear indications of the physics beyond standard model. the findings of nonzero neutrino masses by Super-kamiokande in 1998 triggered a huge interest of experimentalists in neutrino physics.In the present article after discussing the theoretical background concerning massive neutrinos and their status in standard model, latest important long baseline experiments dealing with neutrino oscillations have been discussed. It has been tried to show the important link between the physics behind neutrino oscillation and the software used (GloBES).
