B+ and D(S)+ Decay Constants from Belle and BaBar

PDF Version Also Available for Download.

Description

The Belle and Babar experiments have measured the branching fractions for B{sup +} {yields} {tau}{sup +}{nu} and D{sub s}{sup +} {yields} {mu}{sup +}{nu} decays. From these measurements one can extract the B{sup +} and D{sub s}{sup +} decay constants, which can be compared to lattice QCD calculations. For the D{sub s}{sup +} decay constant, there is currently a 2.1 {sigma} difference between the calculated value and the measured value.
