A Measurement of the Pseudoscalar DecayConstant fDs using Charm-Tagged Events in e+e- Collisions at the Y(4S)

PDF Version Also Available for Download.

Description

The decay constant f{sub D{sub s}} of the pseudoscalar strange charm meson D{sub s}{sup +} is an important benchmark test of the theoretical methods that quantitatively describe the nonperturbative low-energy regime of QCD, the theory of the strong interaction. A confirmation of the validity of these predictive methods, foremost lattice QCD, in the sector of heavy-light meson decay constants increases trust in the calculation of f{sub B}, which is an important number for the measurement of the CKM matrix element V{sub td} in B{sup 0}{bar B}{sup 0}-mixing events. From October 1999 through July 2004, the BABAR experiment, located at the ... continued below

Description

The decay constant f{sub D{sub s}} of the pseudoscalar strange charm meson D{sub s}{sup +} is an important benchmark test of the theoretical methods that quantitatively describe the nonperturbative low-energy regime of QCD, the theory of the strong interaction. A confirmation of the validity of these predictive methods, foremost lattice QCD, in the sector of heavy-light meson decay constants increases trust in the calculation of f{sub B}, which is an important number for the measurement of the CKM matrix element V{sub td} in B{sup 0}{bar B}{sup 0}-mixing events. From October 1999 through July 2004, the BABAR experiment, located at the PEP-II storage ring at the Stanford Linear Accelerator Center, collected 230.2 fb{sup -1} of data in e{sup +}e{sup -} collision at {radical}s = 10.58 GeV. In this thesis, these data are searched for e{sup +}e{sup -} {yields} c{bar c} events by identifying sets of charged and neutral pions and charged kaons, consistent with the decay of a charm meson, D{sup 0}, D{sup +}, D{sub s}{sup +}, or D*{sup +}. A sample of 510,000 charmed mesons with a momentum consistent with e{sup +}e{sup -} {yields} c{bar c} events is identified.
