t->cg, c\gamma, cZ in the Left-Right Supersymmetric Model
  We analyse top quark flavor violating decays into a charm quark and a gluon, photon or Z boson in a supersymmetric model incorporating left-right symmetry. We include loop calculations involving contributions from scalar quarks, gluinos, charginos and neutralinos. We perform the calculations first assuming the minimal (flavor diagonal) scalar quark scenario, and then allowing for arbitrary mixing between the second and third generation of scalar quarks, in both the up and down sectors. In each case we present separately the contributions from gluino, chargino and neutralino loops and compare their respective strengths. In the flavor-diagonal case, the branching ratio cannot exceed 10^-5 (10^-6) for the gluon (photon/Z boson); while for the unconstrained (flavor non-diagonal) case the same branching ratios can reach almost 10^-4 for the gluon, 10^-6 for the photon and 10^-5 for the Z boson, all of which are slightly below the expected reach of LHC.
