Leptonic $D_s$ decays at $B$-factories [PDF]
A. ZupancWe review recent measurements of leptonic $D_s$-meson decays performed by Belle and BaBar collaborations. Described measurements enable experimental extraction of the $D_s$-meson decay constant which can be compared with lattice QCD calculations.View original: http://arxiv.org/abs/1301.7218
