Descrição
In this letter we are using the IceCube experiment to test, phenomenologically, the (3+2) sterile neutrino scenario. As far is known, the presence of sterile states with mass splitting ∆m²∼1 eV² distorts the angular and energy distributions of reconstructed muon events, observed by IceCube, through parametric and MSW resonances. Since the distortions introduced by the sterile neutrino (3+2) scenario appear arround of few TeV, where the Ice-Cube detection is highly optimized, here we have a great opportunity to prove scenarios with sterile states. Supporting by previous works, some considerations have be done in order to guarantee a conservative and robust bounds. Then, by using one year data colleted by IceCube between 2011-2012 we constrain the (3+2) parameter space scenario.
