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.

Spontaneous CP violation and symplectic modular symmetry in Calabi-Yau compactifications [PDF]
Nuclear Physics B, 2021 We explore the geometrical origin of CP and the spontaneous CP violation in Calabi-Yau compactifications. We find that the CP symmetry is identified with an outer automorphism of the symplectic modular group in the large complex structure regime of ...

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.

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.

CP violation at the finite temperature [PDF]
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 ...

Lattice QCD spectroscopy for hadronic CP violation [PDF]
Physics Letters B, 2017 The interpretation of nuclear electric dipole moment (EDM) experiments is clouded by large theoretical uncertainties associated with nonperturbative matrix elements.

The seesaw path to leptonic CP violation [PDF]
European Physical Journal C: Particles and Fields, 2017 Future experiments such as SHiP and high-intensity $$e^+ e^-$$ e + e - colliders will have a superb sensitivity to heavy Majorana neutrinos with masses below $$M_Z$$ M Z .

Enhancement of charm CP violation due to nearby resonances [PDF]
Physics Letters B, 2021 Quantitative understanding of CP violation is extremely important as naturalness reasoning strongly suggests that new physics should be accompanied by beyond the Standard Model CPodd phases. In 2019 LHCb made the first 5σ discovery of CP violation in the

EPJ Web of Conferences, 2022 The existence of CP violation in the decays of strange and beauty mesons is very well established experimentally. On the contrary, CP violation in the decays of charmed particles has been elusive for a long time and has been observed for the first time ...
