Kevin Pitts Marino, Christopher Phillip 2015-09-25T20:03:05Z 2015-09-25T20:03:05Z 10000-01-01 2007 2007 We measure the asymmetry between positive and negative same-sign muon pairs originating from semileptonic decays of pairs of B hadrons. Low transverse momentum dimuon pairs are evaluated to determine B hadron content using a log likelihood fit to two-dimensional impact parameter significance templates. Corrections are made for asymmetries arising from the detector, trigger, and hadrons which are reconstructed as muons. Using 1.1 million muon pairs from data corresponding to an integrated luminosity of 1.6 fb-1, we find 210,000 same-sign muon pairs with both muon candidates coming from B decays. After corrections, we measure a semileptonic asymmetry from neutral B mixing of ASL = 0.0080 +/- 0.0090( stat) +/- 0.0068(syst). This asymmetry can be interpreted as a constraint on the complex phase of the CKM matrix element Vts by using the B0 neutral mixing contribution measured at the B factories. We measure the CP violating asymmetry from Bs mixing to be AsSL = 0.020 +/- 0.028. Made available in DSpace on 2015-09-25T20:03:05Z (GMT).
