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

CP Violation in the Renormalizable Theory of Weak Interaction
, 1973 In a framework of the renormalizable theory of weak interaction, problems of CP-violation are studied. It is concluded that no realistic models of CP-violation exist in the quartet scheme without introducing any other new fields.

Discrete flavour symmetries, neutrino mixing and leptonic CP violation [PDF]
The European Physical Journal C, 2017 The current status of our knowledge of the 3-neutrino mixing parameters and of the CP violation in the lepton sector is summarised. The non-Abelian discrete symmetry approach to understanding the observed pattern of neutrino mixing and the related ...

Implications of the LHCb discovery of CP violation in charm decays [PDF]
Journal of High Energy Physics, 2019 The recent measurement of ∆ACP by the LHCb collaboration requires an 𝒪 (10) enhancement coming from hadronic physics in order to be explained within the SM. We examine to what extent can NP models explain ∆ACP without such enhancements.

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.

Direct CP violation in K0→ππ: Standard Model Status [PDF]
Reports on progress in physics. Physical Society, 2017 In 1988 the NA31 experiment presented the first evidence of direct CP violation in the decay amplitudes. A clear signal with a statistical significance was later established with the full data samples from the NA31, E731, NA48 and KTeV experiments ...
