CP violation and cosmology
نویسنده
چکیده
CP violation may have played a crucial role in the formation of matter in the universe. It must have, if the inflationary cosmology is right, thus ruling out the (very unpalatable) possibility that the baryon asymmetry was an initial condition of the Big Bang. If inflation took place, as most of us believe based on the growing observational evidence, it made the universe devoid of matter and set the stage for reheating. The baryon asymmetry then must have been produced at some later point through CP-violating processes.

We describe the role of CP violation in the generation of the baryon asymmetry of the Universe, in the framework of baryogenesis through leptogenesis, with emphasis on the possible relationship between CP violation at low energies and that required by leptogen-esis. It is emphasized that a direct link between these two manifestations of CP violation only exists in the framework of specific flav...
متن کاملNeutron Electric Dipole Moment Experiments
The possibility of a non-zero value for neutron EDM continues to be of central importance in physics and cosmology. A non-zero neutron EDM would be a direct evidence for time-reversal symmetry violation. It also implies CP-violation under the assumption of CPT invariance. To date, only two examples of CP-violation have been found: decays of neutral K mesons and B mesons. CP-violation is believe...
متن کاملCP Violation in the B System : Measuring New - Physics Parameters
I review CP violation in the standard model (SM). I also describe the predictions for CP violation in the B system, along with signals for physics beyond the SM. I stress the numerous contributions of Pat O’Donnell to this subject. Finally, I discuss a new method for measuring new-physics parameters in B decays. This knowledge will allow us to partially identify any new physics which is found, ...
متن کاملSpontaneous CP violation at the electroweak scale.
Utilizing results on the cosmology of anomalous discrete symmetries we show that models of spontaneous CP violation can in principle avoid the domain wall problem first pointed out by Zel’dovich, Kobzarev and Okun. A small but nonzero θQCD explicitly breaks CP and can lift the degeneracy of the two CP conjugate vacua through nonperturbative effects so that the domain walls become unstable, but ...
متن کاملInvited talk at the IXth International Symposium on Particles, Strings and Cosmology
While the Kobayashi–Maskawa single phase origin of CP violation passed its first crucial precision test in B → J/ψKS, the chirality of weak b-quark couplings has not yet been carefully tested. We discuss recent proposals for studying the chiral and CP-violating structure of these couplings in radiative and in hadronic B decays. Invited talk at the IXth International Symposium on Particles, Stri...
