The first precise measurement of the B0 s − ¯B 0 s oscillation frequency Δms with the CDFII experiment is summarized in this talk. The measurement is performed with 1 fb−1 of data collected at the Fermilab Tevatron hadron collider. We find a signal consistent with flavour oscillations; the probability that such a signal is originated by random fluctuations is 0.2%. We measure Δms = 17.31+0.33 −0.18(stat.)±0.07(syst.) ps−1 [1]. After a brief theoretical overview, I will describe the experimental technique and show the results of the CDF analysis and the |Vtd/Vts| value we infer from this measurement.

Abstract
The first precise measurement of the B0 s − ¯B 0 s oscillation frequency Δms with the CDFII experiment is summarized in this talk. The measurement is performed with 1 fb−1 of data collected at the Fermilab Tevatron hadron collider. We find a signal consistent with flavour oscillations; the probability that such a signal is originated by random fluctuations is 0.2%. We measure Δms = 17.31+0.33 −0.18(stat.)±0.07(syst.) ps−1 [1]. After a brief theoretical overview, I will describe the experimental technique and show the results of the CDF analysis and the |Vtd/Vts| value we infer from this measurement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
