Abstract

We found that in supersymmetric models with R-parity non-conservation (RpSUSY) the b-quarks may appreciably contribute to exotic neutrinoless μ^- -e^- conversion in nuclei via the triangle diagram with two external gluons. This allowed us to extract previously overlooked constraints on the third generation trilinear Rp parameters significantly more stringent than those existing in the literature.
