We consider implications of the loop process \stackrel\ifmmode \else \~\fi\ensuremathν\ensuremath→\ensuremathγ\ensuremathγ in the minimal supersymmetric standard model with R-parity violation (RP) for future experiments, where the sneutrino is produced as the only supersymmetric particle. We present a scenario for the RP couplings, where this clean decay, although rare with Br(\stackrel\ifmmode \else \~\fi\ensuremathν\ensuremath→\ensuremathγ\ensuremathγ)\ensuremath∼10^\ensuremath-6, may be useful for sneutrino detection over a range of sneutrino masses at the CERN Large Hadron Collider. Furthermore, the new \stackrel\ifmmode \else \~\fi\ensuremathν\ensuremathγ\ensuremathγ effective coupling may induce detectable sneutrino resonant production in \ensuremathγ\ensuremathγ collisions, over a considerably wide mass range. We compare \stackrel\ifmmode \else \~\fi\ensuremathν\ensuremath→\ensuremathγ\ensuremathγ, gg throughout the paper with the analogous yet quantitatively very different, Higgs boson \ensuremath→\ensuremathγ\ensuremathγ, gg decays and comment on the loop processes \stackrel\ifmmode \else \~\fi\ensuremathν\ensuremath→WW, ZZ.
