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.

Challenge for spontaneous CP violation in Type IIB orientifolds with fluxes [PDF]
, 2020 We systematically investigate the possibilities of realizing the spontaneous $CP$ violation in Type IIB flux compactifications on toroidal orientifolds.

Observation of Several Sources of CP Violation in B^{+}→π^{+}π^{+}π^{-} Decays.
Physical Review Letters, 2020 Observations are reported of different sources of CP violation from an amplitude analysis of B^{+}→π^{+}π^{+}π^{-} decays, based on a data sample corresponding to an integrated luminosity of 3 fb^{-1} of pp collisions recorded with the LHCb detector.

Revisiting CP violation in D→PP and VP decays [PDF]
Physical Review D, 2019 Direct CP violation in the hadronic charm decays provides a good testing ground for the Kobayashi-Maskawa mechanism in the Standard Model. Any significant deviations from the expectation would be indirect evidence of physics beyond the Standard Model. In

Coloured gravitational instantons, the strong CP problem and the companion axion solution
European Physical Journal C: Particles and Fields, 2022 Quantum gravity introduces a new source of the combined parity (CP) violation in gauge theories. We argue that this new CP violation gets bundled with the strong CP violation through the coloured gravitational instantons. Consequently, the standard axion

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