Abstract
A high statistics sample of photoproduced charm particles from the FOCUS (E831) experiment at Fermilab has been used to search for CP violation in the Cabibbo suppressed decay modes We have measured the following CP asymmetry parameters: A CP (K -K + π + ) = +0.006 ± 0.011 ± 0.005, A CP (K -K + ) = -0.001 ± 0.022 ± 0.015 and A CP (π -π + ) = +0.048 ± 0.039 ± 0.025 where the first error is statistical and the second error is systematic. These asymmetries are consistent with zero with smaller errors than previous measurements.

Search for CP Violation in the decays D+→ KSπ+ and D+→KSK+
Physical Review Letters, 2002
A high-statistics sample of photo-produced charm from the FOCUS (E831) experiment at Fermilab has been used to search for direct CP violation in the decays D + → KSπ + and D + → KSK + . We have measured the following asymmetry parameters relative to D + → K − π + π + : ACP (KSπ + ) = (−1.6±1.5±0.9)%, ACP (KSK + ) = (+6.9±6.0±1.5)% and ACP (KSK + ) = (+7.1±6.1±1.2)% relative to D + → KSπ + . The first errors quoted are statistical and the second are systematic. We have also measured the relative branching ratios and found: Γ(D + →K 0 π + ) / Γ(D + → K − π + π + ) = (30.60 ± 0.46 ± 0.32)%, Γ(D + →K 0 K + ) / Γ(D + → K − π + π + ) = (6.04 ± 0.35 ± 0.30)% and Γ(D
Search for CP violation in D^{+}→K^{-}K^{+}π^{+} decays
Physical Review D, 2011
A model-independent search for direct CP violation in the Cabibbo suppressed decay D + → K − K + π + in a sample of approximately 370,000 decays is carried out. The data were collected by the LHCb experiment in 2010 and correspond to an integrated luminosity of 35 pb −1 . The normalized Dalitz plot distributions for D + and D − are compared using four different binning schemes that are sensitive to different manifestations of CP violation. No evidence for CP asymmetry is found.
Measurement of CP violation observables and parameters for the decays B±-->DK
Physical Review D, 2009
We study the decay B − → DK * − using a sample of 379×10 6 Υ(4S) → BB events collected with the BABAR detector at the PEP-II B-factory. We perform a "GLW" analysis where the D meson decays into either a CP -even (CP +) eigenstate (K + K − , π + π − ), CP -odd (CP −) eigenstate (K 0 S π 0 , K 0 S φ, K 0 S ω) or a non-CP state (K − π + ). We also analyze D meson decays into K + π − from a Cabibbo-favored D 0 decay or doubly suppressed D 0 decay ("ADS" analysis). We measure observables that are sensitive to the CKM angle γ: the partial-rate charge asymmetries A CP ± , the ratios R CP ± of the B-decay branching fractions in CP ± and non-CP decay, the ratio R ADS of the chargeaveraged branching fractions, and the charge asymmetry A ADS of the ADS decays: A CP + = 0.09 ± 0.13 ± 0.06, A CP − = −0.23 ± 0.21 ± 0.07, R CP + = 2.17 ± 0.35 ± 0.09, R CP − = 1.03 ± 0.27 ± 0.13, R ADS = 0.066 ± 0.031 ± 0.010, and A ADS = −0.34 ± 0.43 ± 0.16, where the first uncertainty is statistical and the second is systematic. Combining all the measurements and using a frequentist approach yields the magnitude of the ratio between the Cabibbosuppressed and favored amplitudes, r B = 0.31 with a one two) sigma confidence level interval of [0.24, 0.38] ([0.17, 0.43]). The value r B = 0 is excluded at the 3.3 sigma level. A similar analysis excludes values of γ in the intervals [0, 7] • , [55, 111] • , and [175, 180] • ([85, 99] • ) at the one (two) sigma confidence level. arXiv:0909.3981v1 [hep-ex]

Search for CP violation and a measurement of the relative branching fraction in D+→K-K+π+ decays
Physical Review D, 2005
We report on a search for the CP asymmetry in the singly Cabibbo-suppressed decays D + → K − K + π + and in the resonant decays D + → φπ + and D + → K * 0 K + based on a data sample of 79.9 fb −1 recorded by the BABAR detector. We use the Cabibbo-favored D + s → K − K + π + branching fraction as normalization in the measurements to reduce systematic uncertainties. The CP asymmetries obtained are ACP (K − K + π ± ) = (1.4 ± 1.0(stat.) ± 0.8(syst.)) × 10 −2 , ACP (φπ ± ) = (0.2 ± 1.5(stat.) ± 0.6(syst.)) × 10 −2 , and ACP (K * 0 K ± ) = (0.9 ± 1.7(stat.) ± 0.7(syst.)) × 10 −2 . The relative branching fraction Γ(D + →K − K + π + ) Γ(D + →K − π + π + ) is also measured and is found to be (10.7 ± 0.1(stat.) ± 0.2(syst.)) × 10 −2 .
Search for CP violation through an amplitude analysis of D0 → K+K−π+π− decays
Journal of High Energy Physics, 2019
A search for CP violation in the Cabibbo-suppressed D 0 → K + K −π+π− decay mode is performed using an amplitude analysis. The measurement uses a sample of pp collisions recorded by the LHCb experiment during 2011 and 2012, corresponding to an integrated luminosity of 3.0 fb−1. The D 0 mesons are reconstructed from semileptonic b-hadron decays into D 0 μ − X final states. The selected sample contains more than 160 000 signal decays, allowing the most precise amplitude modelling of this D 0 decay to date. The obtained amplitude model is used to perform the search for CP violation. The result is compatible with CP symmetry, with a sensitivity ranging from 1% to 15% depending on the amplitude considered.
Model-independent search for CP violation in and decays
Physics Letters B, 2013
A search for CP violation in the phase-space structures of D 0 and D 0 decays to the final states K − K + π − π + and π − π + π + π − is presented. The search is carried out with a data set corresponding to an integrated luminosity of 1.0 fb −1 collected in 2011 by the LHCb experiment in pp collisions at a centre-of-mass energy of 7 TeV. For the K − K + π − π + final state, the four-body phase space is divided into 32 bins, each bin with approximately 1800 decays. The p-value under the hypothesis of no CP violation is 9.1%, and in no bin is a CP asymmetry greater than 6.5% observed. The phase space of the π − π + π + π − final state is partitioned into 128 bins, each bin with approximately 2500 decays. The p-value under the hypothesis of no CP violation is 41%, and in no bin is a CP asymmetry greater than 5.5% observed. All results are consistent with the hypothesis of no CP violation at the current sensitivity.

Measurement of CP violation in B 0 → D * ± D ∓ decays
The decay-time-dependent CP asymmetry in B 0 → D * ± D ∓ decays is measured using a data set corresponding to an integrated luminosity of 9 fb −1 recorded by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and 13 TeV. The CP parameters are measured as S D * D = −0.861 ± 0.077 (stat) ± 0.019 (syst) , ∆S D * D = 0.019 ± 0.075 (stat) ± 0.012 (syst) , C D * D = −0.059 ± 0.092 (stat) ± 0.020 (syst) , ∆C D * D = −0.031 ± 0.092 (stat) ± 0.016 (syst) , A D * D = 0.008 ± 0.014 (stat) ± 0.006 (syst). The analysis provides the most precise single measurement of CP violation in this decay channel to date. All parameters are consistent with their current world average values.

Search for CP violation using triple product asymmetries in Λ0 b → pK−π+π−, Λ0 b → pK−K+K− and Ξ0 b → pK−K−π+ decays
Journal of High Energy Physics, 2018
A search for CP and P violation using triple-product asymmetries is performed with Λ b 0 → pK − π + π −, Λ b 0 → pK − K + K − and Ξ b 0 → pK − K − π + decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 fb−1, recorded with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV, respectively. The CP - and P - violating asymmetries are measured both integrating over all phase space and in specific phase-space regions. No significant deviation from CP or P symmetry is found. The first observation of Λ b 0 → pK − χ c0(1P)(→π + π −, K + K −) decay is also reported.

Study of Direct CP Violation in B±→J/ψK±(π±) Decays
Physical Review Letters, 2008
We present a search for direct CP violation in B ± → J/ψK ± (π ± ) decays. The event sample is selected from 2.8 fb −1 of pp collisions recorded by D0 experiment in Run II of the Fermilab Tevatron Collider. The charge asymmetry ACP (B + → J/ψK + ) = +0.0075 ± 0.0061(stat.)±0.0027(syst.) is obtained using a sample of approximately 40 thousand B ± → J/ψK ± decays. The achieved precision is of the same level as the expected deviation predicted by some extensions of the standard model. We also measured the charge asymmetry ACP (B + → J/ψπ + ) = −0.09 ± 0.08(stat.)±0.03(syst.).
