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.

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.

Exploring CP violation in the MSSM. [PDF]
Eur Phys J C Part Fields, 2015 We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximize CP-violating observables subject

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.

CP violation at the finite temperature
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 ...

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 ...

Spontaneous CP violation by modulus τ in A4 model of lepton flavors [PDF]
Journal of High Energy Physics, 2020 We discuss the modular A4 invariant model of leptons combining with the generalized CP symmetry. In our model, both CP and modular symmetries are broken spontaneously by the vacuum expectation value of the modulus τ.

Mixing and CP Violation in the Charm System [PDF]
, 2020 In recent years charm physics has undergone a renaissance, one which has been catalysed by an unexpected and impressive set of experimental results from the $B$-factories, the Tevatron and LHCb.

Two-Higgs-doublet model with soft CP violation confronting electric dipole moments and colliders [PDF]
, 2020 We analyze CP-violating effects in both Electric Dipole Moment (EDM) measurements and future analyses at the Large Hadron Collider (LHC) assuming a 2-Higgs-Doublet Model (2HDM) with "soft" CP-violation.
