Absolute measurement of hadronic branching fractions of the Ds+ meson.
The branching fractions of D(s)(+/-) meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 pb(-1) of e(+)e(-) collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight D(s)(+/-) decays with a double tag technique. In particular we determine the branching fraction B(D(s)(+)-->K(-)K(+}pi(+))=(5.50+/-0...
متن کاملDirect measurements of charmed-D-meson hadronic branching fractions.
A new technique is applied to data collected at the +(3770) resonance to derive charmed D meson branching fractions without relying on the measurement of D production cross sections. Measurements are presented for three decay modes of the Do (K-n+, K-?r-w+r+ and K-7r+r ") and four decay modes of the D+ (K-7r+rr+, K-x+r+~~, Kt?r+ and Kfr+7r "). The resulting branching fractions are significantly...
متن کاملSemileptonic and rare B meson decays into a light pseudoscalar meson
In the framework of a QCD relativistic potential model we evaluate the form factors describing the exclusive decays B → πlν and B → Kll. The present calculation extends a previous analysis of B meson decays into light vector mesons. We find results in agreement with the data, when available, and with the theoretical constraints imposed by the Callan-Treiman relation and the infinite heavy quark...
متن کاملφ-meson photoproduction from nuclei
We study coherent and incoherent φ-meson photoproduction from nuclei. The available data are analyzed in terms of single and coupled channel photoproduction. It is found that the data on coherent photoproduction can be well reproduced within a single channel optical model and show only little room for ω− φ mixing. These data indicate a normal distortion of the φ-meson in nuclei, which is compat...
متن کاملφ-meson in Nuclear Matter
φ-meson mass in nuclear matter (m∗φ) is investigated using an effective Lagrangian of φ interacting with octet baryons. m∗φ decreases by a few % in nuclear matter due to the current conservation and effective nucleon/hyperon masses. Its implication to the p-A and A-A collisions are briefly discussed. Submitted to Prog. Theor. Phys.
