dc.description.abstractThe Alpha Magnetic Spectrometer (AMS) located in the International Space Station, measured anomalous fluxes of positrons and antiprotons. The standard astronomical sources are not enough to describe the fluxes measured. We explain it with physics beyond the Standard Model: the Minimal Supersymmetric Standard Model plus R-Parity Violation. Gravitino, the graviton suṕerpartner, plays a fundamental role in our study because the different gravitino decay channels would contribute to the positron and antiproton fluxes measured by AMS. The main focus of our study is to find the best branching ratios associated with the decay channels, which adjust to AMS measurements, considering gravitino properties as its mass and lifetime.
