R-parity violation and Peccei-Quinn symmetry in GUTs
We address the question whether it is possible in GUTs to obtain R-parity violation with a large {\Delta L{/}\Delta B} hierarchy of strengths so that the proton is stable while phenomenologically interesting L-violation is present. We consider versions of SU(5) with a built-in Peccei-Quinn symmetry...
