Lett. BInternational audienceA search for CP violation in D±→η′π± and D±s→η′π± decays is performed using proton-proton collision data, corresponding to an integrated luminosity of 3 fb−1, recorded by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. The measured CP-violating charge asymmetries are ACP(D±→η′π±)=(−0.61±0.72±0.55±0.12)% and ACP(D±s→η′π±)=(−0.82±0.36±0.24±0.27)%, where the first uncertainties are statistical, the second systematic, and the third are the uncertainties on the ACP(D±→K0Sπ±) and ACP(D±s→ϕπ±) measurements used for calibration. The results represent the most precise measurements of these asymmetries to date

Active-sodium-promoted reductive cleavage of halogenated benzoic acids

The outcome of the reaction between 1 2-diaryl-1 2-disodioethanes and halogenated benzoic acids strongly depends on the nature of both reaction partners Indeed whilst chloro- bromo- and iodobenzoic acids are easily dehalogenated the reductive cleavage of fluorobenzoic acids proceeds to a high extent only in the presence of the dianions endowed with more powerful reducing properties Moreover it was observed that ortho-substituted benzoic acids are more easily dehalogenated than the corresponding pare or meta isomers These observations allowed the development of reaction conditions for the exhaustive or regioselective cleavage of selected polyhalogenated benzoic acids (C) 2010 Elsevier Ltd All rights reserve
