CP violation from string theory [PDF]
Physics Letters B, 2018 We identify a natural way to embed CP symmetry and its violation in string theory. The CP symmetry of the low energy effective theory is broken by the presence of heavy string modes.

Opportunistic CP violation [PDF]
Journal of High Energy Physics, 2023 In the electroweak sector of the Standard Model, CP violation arises through a very particular interplay between the three quark generations, as described by the Cabibbo-Kobayashi-Maskawa (CKM) mechanism and the single Jarlskog invariant J 4.

Proceedings of International Europhysics Conference on High Energy Physics — PoS(hep2001), 2002 Several pieces of direct and indirect evidence now suggest that the Kobayashi-Maskawa mechanism plays a distinguished role for CP violation at the electroweak scale.

AIP Conference Proceedings, 2000 Three possibilities for the origin of CP violation are discussed: (1) the Standard Model in which all CP violation is due to one parameter in the CKM matrix, (2) the superweak model in which all CP violation is due to new physics and (3) the Standard ...

Leptogenesis from low energy CP violation [PDF]
Journal of High Energy Physics, 2019 We revisit the possibility of producing the observed baryon asymmetry of the Universe via thermal leptogenesis, where CP violation comes exclusively from the low-energy phases of the neutrino mixing matrix.

Journal of High Energy Physics, 2021 Solutions of the Strong CP Problem based on the spontaneous breaking of CP must feature a non-generic structure and simultaneously explain a coincidence between a priori unrelated CP-even and CP-odd mass scales.

AIP Conference Proceedings, 1991 An overview of the phenomenology of CP violation is presented. The Standard Model mechanism of CP violation and its main experimental tests, both in the kaon and bottom systems, are discussed.

Exploring CP violation in the MSSM. [PDF]
Eur Phys J C Part Fields, 2015 We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximize CP-violating observables subject

CP violation at colliders [PDF]
Pramana, 1994 The prospects of experimental detection of $CP$ violation at $e^+e^-$ and $pp/p\overline{p}$ colliders are reviewed. After a general discussion on the quantities which can measure $CP$ violation and on the implications of the $CPT$ theorem, various ...

CP violation at the finite temperature
Physics Letters B, 2019 In this letter we explore the CP violation at the finite temperature. We show that a spontaneous CP-violating phase φ may arise at the temperature of the electroweak phase transition, and φ can provide a source term for generating the matter-antimatter ...
