Probing The Standard Model And Beyond With Cp Violation And Particle Cosmology

Abstract

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.
