چکیده
A search for CP violation in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays is performed using pp collision data, corresponding to an integrated luminosity of 3 fb^{-1}, collected using the LHCb detector at center-of-mass energies of 7 and 8 TeV. The flavor of the charm meson is inferred from the charge of the pion in D^{*+}→D^{0}π^{+} and D^{*-}→D[over ¯]^{0}π^{-} decays. The difference between the CP asymmetries in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays, ΔA_{CP}≡A_{CP}(K^{-}K^{+})-A_{CP}(π^{-}π^{+}), is measured to be [-0.10±0.08(stat)±0.03(syst)]%. This is the most precise measurement of a time-integrated CP asymmetry in the charm sector from a single experiment.

Direct CP Violation in B Decays
We discuss several aspects of direct CP asymmetries in B decays, which are very useful in spite of hadronic uncertainties in asymmetry calculations. 1) Asymmetries in decays to D(∗)K(∗), π+π−, ρ+ρ−, providing precision tests for the CKM phase γ. 2) Null tests in B+ → J/ψK+, π+π0, where a nonzero asymmetry provides evidence for New Physics. 3) Isospin and broken flavor SU(3) relations among CP a...
متن کاملTime-dependent CP asymmetries in charm decays
The CKM paradigm has been tested thoroughly over the last 40 years in both the neutral K and B systems. The recent discovery of neutral charm meson mixing has prompted the search for CP violation in D decays. We discuss the prospects of performing time-dependent CP asymmetry measurements at facilities either taking data or under construction. Such measurements can (i) provide precision determin...
متن کاملCP Violation and Mixing Results from FNAL E 791
We review results from FNAL E791 concerning D-D 0 mixing and CP violation in D meson decays. We have searched for mixing in semileptonic D → K+`−ν̄ decays and in hadronic D → K+π− and D → K+π−π+π− decays. We have searched for CP violation in D → K+K−/π+π− and D → φπ+/KK+/K+K−π+/π+π−π+ decays. Finally, we have measured the difference in decay widths ∆Γ between the two mass-eigenstates of the D-D ...
متن کاملRescattering effects in charmless Bu,d,s → PP decays
Final-state interaction effects in charmless Bu,d,s → PP decays are studied. We investigate the B 0 → π+π−, π0π0 rates and the Kπ direct CP violations, which lead to the so-called Kπ puzzle in CP violation. Our main results are as follows: (i) Results are in agreement with data in the presence of FSI. (ii) For B decays, the π+π− and π0π0 rates are suppressed and enhanced respectively by FSI. (i...
متن کاملSearch for CP violation in D 0 and D + decays
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 D+ → K−K+π+, D0 → K−K+ and D0 → π−π+. We have measured the following CP asymmetry parameters: ACP (K −K+π+) = +0.006± 0.011± 0.005, ACP (K −K+) = −0.001± 0.022± 0.015 and ACP (π −π+) = +0.048 ± 0.039 ± 0.025 where t...
متن کاملOn Test of CPT Symmetry in CP -violating B Decays
Considering that the existing experimental limit for CPT violation is still poor, we explore various possible ways to test CPT symmetry in CP -violating B decays at e+e− B factories and hadron machines. We find that it is difficult to distinguish between the effect of direct CP violation and that of CPT violation in the time-integrated measurements of neutral B decays to CP eigenstates such as ...
