International Journal of Modern Physics A, 2007 In this contribution to the Festschrift in honor of Bruce McKellar and Girish Joshi, I discuss a model proposed recently1 in which the CP violating phase in the CKM matrix is identical to the phase in the Higgs potential resulting from spontaneous CP violation.

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 and the strong CP problem
Journal of High Energy Physics, 2017 We derive sufficient conditions that guarantee a robust solution of the strong CP problem in theories with spontaneous CP violation, and introduce a class of models satisfying these requirements. In the simplest scenarios the dominant contribution to the

CP violation from string theory
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.

Sum rules for CP asymmetries of charmed baryon decays in the $$SU(3)_F$$ SU(3)F limit
European Physical Journal C: Particles and Fields, 2019 Motivated by the recent LHCb observation of CP violation in charm, we study CP violation in the charmed baryon decays. A simple method to search for the CP violation relations in the flavor SU(3) limit, which is associated with a complete interchange of ...

CP violation in three-body B decays: a model ansatz
Journal of High Energy Physics, 2020 The mechanism of CP violation remains one of the puzzles in particle physics. Key to understanding this phenomenon are nonleptonic B decays, especially multibody decays which exhibit large CP asymmetries in various regions of phase space.

Hunting for Direct CP Violation in B¯s0⟶π+π−K∗0
Advances in High Energy Physics, 2022 In perturbative QCD approach, based on the first order of isospin symmetry breaking, we study the direct CP violation in the decay of B¯s0⟶ρωK∗0⟶π+π−K∗0.

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.
