On the determination of leptonic CP violation and neutrino mass ordering in presence of non-standard interactions: present status [PDF]

open access: yesJournal of High Energy Physics, 2019
A bstractWe perform a global analysis of neutrino data in the framework of three massive neutrinos with non-standard neutrino interactions which affect their evolution in the matter background.

CP violation in modular invariant flavor models [PDF]

open access: yesPhysical Review D, 2019
We study the spontaneous CP violation through the stabilization of the modulus τ in modular invariant flavor models. The CP-invariant potential has the minimum only at Re[τ]=0 or 1/2(mod 1).

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-like Symmetry with Discrete and Continuous Groups and CP Violation/Restoration [PDF]

open access: yesJHEP 10 (2024) 213, 2023
We study physical implications of general CP symmetry including CP-like symmetry. Various scattering amplitudes of CP asymmetry are calculated in CP-like symmetric models. We explicitly show that the CP-like transformation leads to a specific relation between different CP asymmetries.

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 ...

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.

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

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.
