Experimental Status of Leptonic Ds Decays
arXiv:hep-ex/0109023
Abstract
The measurements of the leptonic branching ratios BR(Ds->tau nu) and BR(Ds->mu nu) are reviewed. The values of the Ds decay constant fDs derived from the measurements are updated and a world average is calculated taking into account the large correlations between the measurements
