We discuss topics related to CP violation and particle cosmology. First, we present some developments in improving the extraction of the CP violating parameter [gamma] from the decay B± [RIGHTWARDS ARROW] DK ± followed by the subsequent decay D [RIGHTWARDS ARROW] KS [pi]+ [pi][-] . The mixing of the final state kaon is an additional CP violating effect which should be taken into account in the extraction of [gamma], and we discuss how this should be done. We also discuss the optimization of phase space binning needed to extract [gamma] from these decays in a model independent way. Next, we discuss some cosmological constraints on R-parity violating, Minimally Flavor Violating (MFV) Supersymmetry (SUSY). Finally, we show that oribtally excited dark matter cannot persist over cosmic timescales for various model independent reasons.
