Abstract:
It is shown, contrary to the recent claim in literature, that gluino exchange in supersymmetric proton decay does not vanish in general. In N=1 supergravity theory it could be an important or even dominant contribution, which would imply the often-mentioned model independent main mode . We also summarize the situation in the case of charged W-ino exchange incorporating the new measurement of B meson lifetimes.
