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

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

Spontaneous CP Violation [PDF]
, 1998 In this talk I begin with some general discussion of the history of CP violation, then move on to aspects of the aspon model including the production of new particles at LHC, implications for B decay, generalized Cabibbo mixing and a reevaluation of kaon

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.

, 1998 $B$ flavor tagging will be extensively studied at the asymmetric $B$ factories due to its importance in CP asymmetry measurements. The primary tagging modes are the semileptonic decays of the $b$ (lepton tag), or the hadronic $b \to c (\to s)$ decays ...

Discrete flavour symmetries, neutrino mixing and leptonic CP violation [PDF]
The European Physical Journal C, 2017 The current status of our knowledge of the 3-neutrino mixing parameters and of the CP violation in the lepton sector is summarised. The non-Abelian discrete symmetry approach to understanding the observed pattern of neutrino mixing and the related ...

CP Violation in a Multi-Higgs Doublet Model [PDF]
, 1994 We study CP violation in a multi-Higgs doublet model based on a $S_3 \times Z_3$ horizontal symmetry. We consider two mechanisms for CP violation in this model: a) CP violation due to complex Yukawa couplings; and b) CP violation due to scalar ...

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.

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.
