Update on the improved lattice calculation of direct CP-violation in K decays [PDF]

open access: yesProceedings of 37th International Symposium on Lattice Field Theory — PoS(LATTICE2019), 2019
We provide an update on the RBC & UKQCD lattice calculation of the measure of Standard Model direct CP-violation in kaon decays, $\epsilon'$

CP violation in SUSY [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2001
Supersymmetry exhibts new sources of CP violation. We discuss the implications of these new contributions to CP violation both in the K and B physics. We show that CP violation puts severe constraints on low energy SUSY, but it represents also a promising ground to look for signals of new physics.

Search for CP Violation in Neutrino and Antineutrino Oscillations by the T2K Experiment with 2.2×10^{21} Protons on Target. [PDF]

open access: yesPhysical Review Letters, 2018
The T2K experiment measures muon neutrino disappearance and electron neutrino appearance in accelerator-produced neutrino and antineutrino beams. With an exposure of 14.7(7.6)×10^{20} protons on target in the neutrino (antineutrino) mode, 89 ν_{e ...

CP Violation in Higgs-Gauge Interactions: From Tabletop Experiments to the LHC. [PDF]

open access: yesPhysical Review Letters, 2019
We investigate the interplay between the high- and low-energy phenomenology of CP-violating interactions of the Higgs boson with gauge bosons. For this purpose, we use an effective field theory approach and consider all dimension-six operators arising in

Spontaneous CP violation and symplectic modular symmetry in Calabi-Yau compactifications

open access: yesNuclear 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 ...

Exploring dynamical CP violation induced baryogenesis by gravitational waves and colliders [PDF]

open access: yesPhysical Review D, 2018
By assuming a dynamical source of CP violation, the tension between sufficient CP violation for successful electroweak baryogenesis and strong constraints from current electric dipole moment measurements could be alleviated.

Direct CP violation in Cabibbo-favored charmed meson decays and ϵ′/ϵ in SU(2)L × SU(2)R × U(1)B−L model [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractSince the standard model contribution is virtually absent, any observation of direct CP violation in the Cabibbo-favored charmed meson decays would be evidence of new physics. In this paper, we conduct a quantitative study on direct CP violation

Observation of CP Violation in Charm Decays.

open access: yesPhysical Review Letters, 2019
A search for charge-parity (CP) violation in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays is reported, using pp collision data corresponding to an integrated luminosity of 5.9  fb^{-1} collected at a center-of-mass energy of 13 TeV with the LHCb detector.

CP violation and modular symmetries [PDF]

open access: yes, 2001
We reconsider the origin of CP violation in fundamental theory. Existing string models of spontaneous CP violation make ambiguous predictions, due to the arbitrariness of CP transformation and the apparent non-invariance of the results under duality.
