Decaimientos de esneutrinos

Abstract

Based on the Minimal Supersymmetric Standard Model (MSSM), we discussed possible two body decay modes for the sneutrino $\widetilde{\nu}$, one charged and other neutral: $\widetilde{\nu}\rightarrow l \widetilde{\chi}_1^\pm$ and $\widetilde{\nu}\rightarrow \nu \widetilde{\chi}_1^0$, respectively. Exploring a range of possible values for its mass, and for the chargino $\widetilde{\chi}_i^\pm$ and neutralino $\widetilde{\chi}_j^0$ masses as well. We present the specific calculation for branching ratios, which are analyzed numerically.
