Recent Experimental Results on Leptonic $D_{(s)}^{+}$ Decays, Semileptonic $D$ Decays and Extraction of $\mathrm{\mid }{V}_{cd(s)}\mathrm{\mid }$

The recent experimental results on leptonic $D_{(s)}^{+}$ decays, semileptonic $D$ decays, determinations of decay constants and form factors, as well as extractions of $\mathrm{\mid }{V}_{cd}\mathrm{\mid }$ and $\mathrm{\mid }{V}_{cs}\mathrm{\mid }$ are briefly reviewed. Global analysis of all existing measurements of leptonic $D_{(s)}^{+}$ decays and semileptonic $D$ decays yields $\mathrm{\mid }{V}_{cd}\mathrm{\mid }=0.2157\pm 0.0045$ and $\mathrm{\mid }{V}_{cs}\mathrm{\mid }=0.983\pm 0.011$, which are the most precision determinations of these two CKM matrix elements up to date.
