| 英文摘要 | A search for cp violation in d-+/- -> eta 'pi(+/-) and d-s(+/-) -> eta 'pi(+/-) 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 a(cp)(d-+/- -> eta 'pi(+/-)) = (-0.61 +/- 0.72 +/- 0.53 +/- 0.12)% and a(cp)(d-s(+/-) -> eta 'pi(+/-)) = (-0.82 +/- 0.36 +/- 0.22 +/- 0.27)%, where the first uncertainties are statistical, the second systematic, and the third are the uncertainties on the a(cp)(d-+/- -> k-s(0)pi(+/-)) and a(cp)(d-s(+/-) -> phi pi(+/-)) measurements used for calibration. the results represent the most precise measurements of these asymmetries to date.
