We present an update of the branching ratios for Higgs-boson decays in the Standard Model. We list results for all relevant
branching ratios together with corresponding uncertainties resulting from input parameters and missing higher-order corrections.
As sources of parametric uncertainties we include the masses of the charm, bottom, and top quarks as well as the QCD coupling
constant. We compare our results with other predictions in the literature. 相似文献

The reconstruction of the energy and momentum of isolated electrons in CMS combining tracking and electromagnetic calorimetry
information is described. The emphasis is put on primary electrons with transverse momentum below 50 GeV/c. The energy deposited
in the electromagnetic calorimeter is measured in clusters of clusters (superclusters) which collect bremsstrahlung photons
emitted along the electron trajectory in the tracker volume. The electron tracks are built from seeds in the pixel detector
found via a cluster-driven pixel hit matching algorithm, followed by a reconstruction of trajectories in the silicon strip
tracker with a Gaussian sum filter. Electrons are classified using observables sensitive to the pattern of bremsstrahlung
emission and electromagnetic showering in the tracker material. Energy scale corrections depending on the electron class are
applied to the supercluster and estimates of associated errors are obtained. The electron energy is deduced from a weighted
combination of the corrected supercluster energy and tracker momentum measurements. The electron direction is that of the
reconstructed electron track at interaction vertex. The pre-selection of isolated electron candidates for physics analysis
is described. Class-dependent observables combining tracking and calorimetry information are discussed for electron identification. 相似文献
