The measurement of the Bsmixing oscillation frequency, Δms, has been the main goal for both experiments CDF and D0 which are running at the Tevatron collider. With 1 fb−1 of data collected during the last four years D0 set a lower and upper limit on this frequency, 17 < Δms < 21 ps−1. CDF measured Δms with a precision better than 2% and the probability that the data could randomly fluctuate to mimic such a signature is 0.2%

Abstract
The measurement of the Bsmixing oscillation frequency, Δms, has been the main goal for both experiments CDF and D0 which are running at the Tevatron collider. With 1 fb−1 of data collected during the last four years D0 set a lower and upper limit on this frequency, 17 < Δms < 21 ps−1. CDF measured Δms with a precision better than 2% and the probability that the data could randomly fluctuate to mimic such a signature is 0.2%File in questo prodotto:
