CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe measure time-integrated CP-violating asymmetries of neutral charmed mesons in the modes D(0)-> K(-)K(+) and D(0)->pi(-)pi(+) with the highest precision to date by using D(0)-> K(-)pi(+) decays to correct detector asymmetries. An analysis of 385.8 fb(-1) of data collected with the BABAR detector yields values of a(CP)(KK)=(0.00 +/- 0.34(stat)+/- 0.13(syst))% and a(CP)(pi pi)=(-0.24 +/- 0.52(stat)+/- 0.22(syst))%, which agree with standard model predictions.
