Measurements of Branching Fractions and CP-Violating Asymmetries in B Meson Decays to Charmless Two-Body States Containing a K0

B. Aubert, BABAR Collaboration

We present measurements of branching fractions and \CP-violating asymmetries in decays of mesons to two-body final states containing a \Kz. The results are based on a data samp…

Vacuum Polarisation and Hadronic Contribution to muon g-2 from Lattice QCD

M. Göckeler, R. Horsley, W. Kürzinger +3

We compute the vacuum polarisation on the lattice in quenched QCD using non-perturbatively improved Wilson fermions. Above Q^2 of about 2 GeV^2 the results are very close to the pr…

Measurement of the Branching Fraction for B- --> D0 K*-

B. Aubert, BABAR Collaboration

We present a measurement of the branching fraction for the decay B- --> D0 K*- using a sample of approximately 86 million BBbar pairs collected by the BaBar detector from e+e- coll…

W Boson Polarisation at LEP2

The OPAL collaboration, G. Abbiendi

Elements of the spin density matrix for W bosons in e+e- -> W+W- -> qqln events are measured from data recorded by the OPAL detector at LEP. This information is used calculate pola…

Measurement of the partial widths of the Z into up- and down-type quarks

The OPAL collaboration, G. Abbiendi

Using the entire OPAL LEP1 on-peak Z hadronic decay sample, Z -> qbarq gamma decays were selected by tagging hadronic final states with isolated photon candidates in the electromag…

Conjugacy for positive permutation braids

Hugh R. Morton, Richard J. Hadji

Positive permutation braids on n strings, which are defined to be positive n-braids where each pair of strings crosses at most once, form the elementary but non-trivial building bl…
