We perform analytic computations of the signal branching fractions in the framework of effective field theory, with a single nonzero RPV operator $\\lambda''_{ij3}\\bar{U}_{i}^c\\bar{D}_{j}^c\\bar{D}_3^c$, where $i,j=1,2$. The hadronic form factors are calculated using an SU(3) phenomenological Lagrangian approach for the proton, as well as several hyperons and charmed baryons.
