چکیده
Absolute branching fractions for the 013 and D/4 decays D++I?‘e+v, , D++K’p+v,, D++K*‘e+v, , and D’+K*-e+v, are determined using completely reconstructed D D events at the y(3770). Reconstructed D’+K-e+v, decays are used to determine the pole mass of the f+($‘) form factor. Resonant K* production dominates the process D+Kxev, the K” polarization is measured. Limits on several Cabibbo suppressed channels are evaluated. A global fit imposing isospin symmetry is performed to the measured exclusive and inclusive semileptonic Do and D+ branching fractions and the lifetime ratio z,+/z,+ to obtain an improved set of branching fractions.

“Seeing” the Difference: The Importance of Visibility and Action as a Mark of “Authenticity” in Co-production; Comment on “Collaboration and Co-production of Knowledge in Healthcare: Opportunities and Challenges”
The Rycroft-Malone paper states that co-production relies on ‘authentic’ collaboration as a context for action. Our commentary supports and extends this assertion. We suggest that ‘authentic’ co-production involves processes where participants can ‘see’ the difference that they have made within the project and beyond. We provide examples including: the use of design in health projects which see...
متن کاملEl RECENT RESULTS ON D MESON DECAYS FROM THE MARK III
The MARK III Collaboration recently completed the analysis of a number of decay modes of charged and neutral D mesons produced in electron-positron collisions near the peak of the $(3770) resonance at SLAC’s SPEAR storage ring. The mesons were produced nearly at rest in pairs, either D+Dor DoDo, at a center-of-mass energy below the threshold for DD* production. The unique kinematics of the prod...

متن کاملHADRONIC DECAYS OF THE Q (2980)* The MARK III Collaboration
From a studyof 2.7 million J/I/J decays with the MARK III detector at SPEAR, we determine branching ratios for decays of the Q to q?r+~-, x*KrKs, T+T-T+T-, ?r+r-K+K-, pp, the previously unobserved modes q’?r+x-, I~OK+K-, K*qfg+, K*q*O, and new upper limits on pp, ww, 6~, A2 T, ~T,J and r]KK. When combined, the different measurements of the qc mass yield (2980.2 f 1.6) MeV/c2. In the decays Q + ...
