Abstract： Phenomenological analysis to the R-parity violating supersymmetry with a vector-like extra generation is performed in detail. It is found that, via the trilinear couplings, the correct neutrinospectrum can be obtained. The Higgs mass rises to 125 GeV by new up-type Yukawa couplings of vector-like quarks with no need of very heavy superpartners. Phenomena of new heavy fermions at LHC are predicted.

Abstract： The minimal dark matter model is given a supersymmetric extension. A super SU(2)L quintupletis introduced with its fermionic neutral component still being the dark matter, the dark matterparticle mass is about 19.7 GeV. Mass splitting among the quintplet due to supersymmetry particles is found to be negligibly small compared to the electroweak corrections. Other properties of this supersymmetry model are studied, it has the solutions to the PAMELA and Fermi-LAT anomaly,the predictions in higher energies need further experimental data to verify.

Abstract： LHCb collaboration has recently announced a measurement of the difference of time-integrated CP asymmetries between D → K+K− and D → #25;+#25;−. This result provides the evidence of large direct CP violation in D meson and reveals some important implications on underlying new physics. It is shown that the direct CP violation in D meson can be enhanced by R-parityviolating supersymmetry, while CP violations in K and B mesons are suppressed by this newphysics, which is in consistence with previous experiments. Constraints on the model parametersand some consequences are also discussed.
