Stefan Soldner-Rembold
TL;DR
This paper reviews experimental measurements of leptonic Ds decays, updates the decay constant fDs, and calculates a world average considering measurement correlations.
Contribution
It provides a comprehensive review and updated calculation of the Ds decay constant based on recent leptonic decay measurements.
Findings
Updated values of BR(Ds->tau nu) and BR(Ds->mu nu)
Calculated world average of fDs
Analysis of measurement correlations
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
