Spontaneous CP Violation [PDF]
, 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 in a Multi-Higgs Doublet Model [PDF]
, 1994 We study CP violation in a multi-Higgs doublet model based on a $S_3 \times Z_3$ horizontal symmetry. We consider two mechanisms for CP violation in this model: a) CP violation due to complex Yukawa couplings; and b) CP violation due to scalar ...

CP violation at colliders [PDF]
, 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 ...

, 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 ...

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.

CP violation in D-meson decays
EPJ Web of Conferences, 2014 Since most probably Standard Model cannot explain large value of CP asymmetries recently observed in D-meson decays the fourth quark-lepton generation explanation of it is proposed.

Journal of High Energy Physics, 2023 CP violation plays a very important role in nature with implications both for Particle Physics and for Cosmology. Accounting for the observed matter-antimatter asymmetry of the Universe requires the existence of new sources of CP violation beyond the ...

Leptogenesis from low energy CP violation
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.
