Observation of CP Violation in Charm Decays.
Physical 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.

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]
Journal 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

Spontaneous CP violation and the strong CP problem
Journal of High Energy Physics, 2017 We derive sufficient conditions that guarantee a robust solution of the strong CP problem in theories with spontaneous CP violation, and introduce a class of models satisfying these requirements. In the simplest scenarios the dominant contribution to the

Electroweak Baryogenesis from Dark-Sector CP Violation. [PDF]
Physical Review Letters, 2018 We present a novel mechanism of electroweak baryogenesis where CP violation occurs in a dark sector, comprised of standard model gauge singlets, thereby evading the strong electric dipole moment constraints.

Hunting for Direct CP Violation in B¯s0⟶π+π−K∗0
Advances in High Energy Physics, 2022 In perturbative QCD approach, based on the first order of isospin symmetry breaking, we study the direct CP violation in the decay of B¯s0⟶ρωK∗0⟶π+π−K∗0.

Implications of the LHCb discovery of CP violation in charm decays [PDF]
Journal of High Energy Physics, 2019 The recent measurement of ∆ACP by the LHCb collaboration requires an 𝒪 (10) enhancement coming from hadronic physics in order to be explained within the SM. We examine to what extent can NP models explain ∆ACP without such enhancements.

Sum rules for CP asymmetries of charmed baryon decays in the $$SU(3)_F$$ SU(3)F limit
European Physical Journal C: Particles and Fields, 2019 Motivated by the recent LHCb observation of CP violation in charm, we study CP violation in the charmed baryon decays. A simple method to search for the CP violation relations in the flavor SU(3) limit, which is associated with a complete interchange of ...
