CPT and CP, an entangled couple
Journal of High Energy Physics, 2020 Even though it is undoubtedly very appealing to interpret the latest T2K results as evidence of CP violation, this claim assumes CPT conservation in the neutrino sector to an extent that has not been tested yet.

Probing CP violation with non-unitary mixing in long-baseline neutrino oscillation experiments: DUNE as a case study [PDF]
, 2016 When neutrino masses arise from the exchange of neutral heavy leptons, as in most seesaw schemes, the effective lepton mixing matrix N describing neutrino propagation is non-unitary, hence neutrinos are not exactly orthonormal.

Direct CP Violation in Charmless Three-body Decays of $B$ Mesons [PDF]
, 2016 Direct CP violation in charmless three-body hadronic decays of $B$ mesons is studied within the framework of a simple model based on the factorization approach.

International Journal of Modern Physics A, 2007 In this contribution to the Festschrift in honor of Bruce McKellar and Girish Joshi, I discuss a model proposed recently1 in which the CP violating phase in the CKM matrix is identical to the phase in the Higgs potential resulting from spontaneous CP violation.

Unparticles and CP-violation [PDF]
Journal of Physics: Conference Series, 2008 We give a brief summary of the unparticle scenario proposed by Georgi. The CP-even phase of the propagator is exploited to study the CP-asymmetry in B+ --> tau+ + nu, which is neither experimentally searched for nor predicted by any other model. Furthermore we show that the novel CP-violation is consistent with the CPT theorem by identifying the CP ...

The Optical Analogue of CP Violation [PDF]
Foundations of Physics Letters, 1996 The peculiar features of the mixing in the neutral pseudoscalar mesons K0--antiK0 can be introduced by the analogy to the optical polarization. The time-reversed not-invariant processes and the related phenomenon of CP-nonconservation can be then joined to the dissipative effects which yield a not vanishing imaginary part in the relevant propagation of

Flavour and CP Violation [PDF]
Journal of Physics: Conference Series, 2013 In this talk I review the status of B mixing in the Standard Model and the room for new physics in B_s and B_d mixing in the light of recent LHCb data.

Pseudo-Goldstone dark matter model with CP violation
Journal of High Energy Physics, 2022 We consider an explicitly CP-violating model with two Higgs doublets and one complex singlet scalar. The singlet S is charged under a global U(1) symmetry which is softly broken by a mass term μ 2 S 2 + H.c..

CP violation in multibody B decays from QCD factorization [PDF]
, 2017 A bstractWe test a data-driven approach based on QCD factorization for charmless three-body B-decays by confronting it to measurements of CP violation in B− → π−π+π−.
