We report the observation of a narrow state decaying into $J/\psi\pi^+\pi^-$ and produced in $220 pb^{-1}$ $\bar{p} p $ collisions at $\sqrt{s}=1.96 TeV$ CDF II experiment. observe 730 \pm 90 decays. The mass is measured to be $3871.3 0.7 (stat) 0.4 (syst) MeV/c2$, with an observed width consistent detector resolution. This agreement recent by Belle Collaboration X(3872) meson.
This volume details leading edge orthognathic and reconstructive surgery procedures. Coverage explains the why's of maxillary mandibular combined surgical procedures, how to perform techniques their results. The book also stresses diagnosis treatment planning.
Computational grids process large, computationally intensive problems on small data sets. In contrast, large computational that in turn require evaluating, mining and producing amounts of data. Replication, creating geographically disparate identical copies data, is regarded as one the major optimization techniques for reducing access costs. this paper, several replication algorithms are discussed. These were studied using Grid simulator: OptorSim. OptorSim provides a modular framework...
We report on measurements of differential cross sections dsigma/dp(T) for prompt charm meson production in ppmacr; collisions at sqrt[s]=1.96 TeV using 5.8+/-0.3 pb(-1) data from the CDF II detector Fermilab Tevatron. The are collected with a new trigger that is sensitive to long lifetime hadrons containing heavy flavor. measured central rapidity region |y|</=1 four fully reconstructed decay modes: D0-->K-pi(+), D(*+)-->D0pi(+), D+-->K-pi(+)pi(+), D(+)(s)-->phipi(+), and their charge...
The growth and development of ``charged particle jets'' produced in proton-antiproton collisions at $1.8 \mathrm{TeV} $ are studied over a transverse momentum range from $0.5$ $\mathrm{GeV}/c$ to $50$ $\mathrm{GeV}/c.$ A variety leading (highest momentum) charged jet observables compared with the QCD Monte Carlo models HERWIG, ISAJET, PYTHIA. describe fairly well multiplicity distribution particles within jet, size radial around direction, jet. direction jet'' each event is used define three...
Optimising the use of Grid resources is critical for users to effectively exploit a Data Grid. replication considered major technique reducing data access cost jobs. This paper evaluates novel strategy, based on an economic model, that optimises both selection replicas running jobs and dynamic creation in sites. In our optimisation agents are located sites auction protocol selecting optimal replica file prediction function make informed decisions about local replication. We evaluate strategy...
We report on measurements of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) differential cross sections (d(2)sigma/dp(T)dy)(/y/<0.4), as well Upsilon(1S) polarization in p macro collisions at square root s = 1.8 TeV using a sample 77+/-3 pb(-1) collected by collider detector Fermilab. The three resonances were reconstructed through decay Upsilon-->mu(+)mu(-). measured angular distribution muons rest frame is consistent with unpolarized meson production.
