C 3 DS Requirement Analysis

By considering the problems to be solved from a software engineering point of view, we will not only consider the feasibility provided by the mechanisms embedded in the platform we are defining, but also the economic1 aspects. This last point burns down to: how easy will it be to implement, deploy and manage complex distributed services in the application domains we are considering, i.e. firewa...

Chiral radiative corrections and Ds(2317)/D(2308) mass puzzle

Measurement of the D0, D+, and Ds+ meson lifetimes.

We report measurements of the lifetimes of the D, D+, and D,+ (F+) mesons produced in e+e collisions at a center-of-mass energy of 29 GeV. The decay vertex distribution in the processes D ~K rr+, D+~E n+n+, and . D+~Prr+ were made using a vertex chamber installed in the High Resolution Spectrometer at the SLAC storage ring PEP. The measured lifetimes are ~ 0=(4.4+1.0%0.6)X10 ' s, w +=(9.2+,'3+1...

Measurements of D and Ds decay constants at CLEO

Meson decay constants in the B system are used to translate measurements of BB̄ mixing to CKMmatrix elements. Currently, it is not possible to determine fB accurately from leptonic B decays, so theoretical calculations of fB are used. Since the B s meson does not have l ν decays, it will never be possible to determine fBs experimentally, thus theory must be relied on. If calculations disagree on...
