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

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

CP-violation [PDF]

open access: yesAIP Conference Proceedings, 1992
An overview of the phenomenology of CP violation is presented. The Standard Model mechanism of CP violation and its main experimental tests, both in the kaon and bottom systems, are discussed. (Lectures given at the 1993 Trieste Summer School and at the Escuela Latinoamericana de Fisica, ELAF'93, Argentina).

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.

Spontaneous CP violation and the strong CP problem

open access: yesJournal 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

Sub-GeV Atmospheric Neutrinos and CP Violation in DUNE. [PDF]

open access: yesPhysical Review Letters, 2019
We propose to use the unique event topology and reconstruction capabilities of liquid argon time projection chambers to study sub-GeV atmospheric neutrinos.

A U-spin anomaly in charm CP violation

open access: yesJournal of High Energy Physics, 2023
Recent LHCb data shows that the direct CP asymmetries of the decay modes D 0 → π + π − and D 0 → K + K − have the same sign, violating an improved U-spin limit sum rule in an unexpected way at 2.1σ.

Electroweak Baryogenesis from Dark-Sector CP Violation. [PDF]

open access: yesPhysical 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.
