Spontaneous CP violation in supersymmetric QCD

open access: yesJournal of High Energy Physics
We investigate a composite model of spontaneous CP violation based on a new supersymmetric QCD as a solution to the strong CP problem. The scalar components of the meson chiral superfields obtain complex vacuum expectation values to break CP symmetry ...

Lattice QCD spectroscopy for hadronic CP violation

open access: yesPhysics Letters B, 2017
The interpretation of nuclear electric dipole moment (EDM) experiments is clouded by large theoretical uncertainties associated with nonperturbative matrix elements.

Measurements of B meson decay rates and CP violation asymmetries [PDF]

open access: yes, 2011
Hadrons containing b-quarks represent a great opportunity to investigate the flavor sector of the Standard Model (SM) and to look for New Physics effects (NP).

Double-mixing CP violation in B decays

open access: yesEuropean Physical Journal C: Particles and Fields
We study a long-overlooked CP violation observable, termed double-mixing CP violation, which arises from the interference between two neutral meson oscillating paths involved in a decay chain.

Beautiful CP violation

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
CP violation is observed to date only in K^0 decays and is parameterizable by a single quantity epsilon. Because it is one of the least understood phenomena in the Standard Model and holds a clue to baryogenesis, it must be investigated further. Highly specialized searches in K^0 decays are possible. Effects in B decays are much larger.

Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays [PDF]

open access: yes, 2012
Measurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data ...

Mixing and CP violation in the beauty and charm sectors at LHCb

open access: yesEPJ Web of Conferences, 2014
The LHCb detector is a dedicated heavy flavour experiment operating at the Large Hadron Collider designed to pursue an extensive study of CP violation in the beauty and charm sectors.

Challenges posed by non-standard neutrino interactions in the determination of δCP at DUNE

open access: yesNuclear Physics B, 2018
One of the primary objectives of the Deep Underground Neutrino Experiment (DUNE) is to discover the leptonic CP violation and to identify its source. In this context, we study the impact of non-standard neutrino interactions (NSIs) on observing the CP ...

CP violation with BaBar

open access: yes, 1998
The BABAR experiment is a new generation detector located at the SLAC B factory PEP-II ring which should start taking data at the end of 1999. Its main goal is the study of CP violation in the B0-B0b system. After explaining the nature of this CP violation, I review the scientific program for achieving this study in many different modes, in the light ...

CP violation in charm

open access: yes, 2007
CP-violating asymmetries in charm provide a unique probe of physics beyond the Standard Model. I review several topics relevant to searches for CP-violation in charmed meson and baryon transitions.
