Process for metal deposition for microelectronic interconnections
A method for forming interconnections in microelectronic devices, including interconnections through small vias between different layers in the microelectronic devices include the spin coating of a film comprising a polyoxometalate and an organic material on the substrate. The film is optionally patterned by lithography, the polymer is removed, and the polyoxometalate is reduced to a metal layer. The metal layer may in one embodiment provide a nucleating zone for the deposition of metal.Board of Regents, University of Texas Syste
Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron
The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of TeV. We report the results of combinations of the inclusive asymmetries and their differential dependencies on relevant kinematic quantities. The combined inclusive asymmetry is . The combined inclusive and differential asymmetries are consistent with recent standard model predictions
Observation of the Baryonic Flavor-Changing Neutral Current Decay Lambda(0)(b) -> Lambda mu(+)mu(-)
We report the first observation of the baryonic flavor-changing neutral current decay Lambda(0)(b) -> Lambda mu(+)mu(-) with 24 signal events and a statistical significance of 5.8 Gaussian standard deviations. This measurement uses a p (p) over bar collisions data sample corresponding to 6.8 fb(-1) at root s = 1.96 TeV collected by the CDF II detector at the Tevatron collider. The total and differential branching ratios for Lambda(0)(b) -> Lambda mu(+)mu(-) are measured. We find B(Lambda(0)(b) -> Lambda mu(+)mu(-)) = [1.73 +/- 0.42(stat) +/- (syst)] x 10(-6). We also report the first measurement of the differential branching ratio of B-s(0) -> phi mu(+)mu(-), using 49 signal events. In addition, we report branching ratios for B+ -> K+mu(+)mu(-), B-0 -> K-0 mu(+)mu(-), and B -> K*(892)mu(+)mu(-) decays.
