$D$轻子和半轻子衰变

$D$ leptonic and semileptonic decays

Hailong Ma

摘要:

本文利用BESIII探测器在质心能量为$\sqrt s=3.773$ GeV处获得的2.92 fb $^{-1}$数据,报道了最近在BESIII对轻子衰变$f_{D^+}$和半轻子衰变$D^0\to K(π)^-e^+ν_e$、$D^+\to K^0_L e^+ν_e$、$D^+\to K^-π^+e^+ν_e$和$D^+\to ω(ϕ)e^+ν_e$的分析结果.

英文摘要:

Based on 2.92 fb$^{-1}$ data taken at the center-of-mass energy $\sqrt s=3.773$ GeV with the BESIII detector, we report recent results on the decay constant $f_{D^+}$, the hadronic form factors, as well as the quark mixing matrix elements $|V_{cs(d)}|$, which are extracted from analyses of the leptonic decay $D^+ \to μ^+ν_μ$ and the semileptonic decays $D^0\to K(π)^-e^+ν_e$, $D^+\to K^0_L e^+ν_e$, $D^+\to K^-π^+e^+ν_e$ and $D^+\to ω(ϕ)e^+ν_e$ at BESIII.
