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), 2001 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. This talk provides a general overview of CP violation in its various contexts, emphasizing CP violation in flavour-violating interactions, such as due to the Kobayashi-Maskawa mechanism. I

Spontaneous CP violation [PDF]
AIP Conference Proceedings, 1998 In this talk I begin with some general discussion of the history of CP violation, then move on to aspects of the aspon model including the production of new particles at LHC, implications for B decay, generalized Cabibbo mixing and a reevaluation of kaon CP violation. Finally there is a summary.

, 1998 $B$ flavor tagging will be extensively studied at the asymmetric $B$ factories due to its importance in CP asymmetry measurements. The primary tagging modes are the semileptonic decays of the $b$ (lepton tag), or the hadronic $b \to c (\to s)$ decays (kaon tag). We suggest that looking for time dependent CP asymmetries in events where one $B$ is tagged

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.

Nuclear Physics B - Proceedings Supplements, 2001 Supersymmetry exhibts new sources of CP violation. We discuss the implications of these new contributions to CP violation both in the K and B physics. We show that CP violation puts severe constraints on low energy SUSY, but it represents also a promising ground to look for signals of new physics.

CP violation induced by the double resonance for pure annihilation decay process in perturbative QCD
European Physical Journal C: Particles and Fields, 2017 In a perturbative QCD approach we study the direct CP violation in the pure annihilation decay process of $$\bar{B}^0_{s}\rightarrow \pi ^+\pi ^-\pi ^+\pi ^-$$ B ¯ s 0 → π + π - π + π - induced by the $$\rho $$ ρ and $$\omega $$ ω double resonance effect.

Challenges posed by non-standard neutrino interactions in the determination of δCP at DUNE
Nuclear Physics B, 2018 One of the primary objectives of the Deep Underground Neutrino Experiment (DUNE) is to discover the leptonic CP violation and to identify its source. In this context, we study the impact of non-standard neutrino interactions (NSIs) on observing the CP ...

, 2002 In these lecture notes an introduction is given to some ideas and attempts to understand the origin of the matter-antimatter asymmetry of the universe. After the discussion of some basic issues of cosmology and particle theory the scenarios of electroweak baryogenesis, GUT baryogenesis, and leptogenesis are outlined.
