Whether new data on $D_{s} \to f_{0} (980) e^{+} ν_{e}$ can be understood if $f_{0} (980)$ consists of only the conventional $q q ˉ$ structure

Hong-Wei Ke, Xue-Qian Li, Zheng-Tao Wei

Only two isospin-singlet scalar mesons $f_{0} (600)$ ( $σ$ ) and $f_{0} (980)$ exist below 1 GeV, so that it is natural to suppose that they are two energy eigenstates which are mixtures o…

Interpretation of the " $f_{D_{s}}$ puzzle" in SM and beyond

Zheng-Tao Wei, Hong-Wei Ke, Xiao-Feng Yang

The recent measurement on the decay constant of $D_{s}$ shows a discrepancy between theory and experiment. We study the leptonic and semileptonic decays of $D$ and $D_{s}$ simultaneous…

Radiative Neutrino Mass in Type III Seesaw Model

Yi Liao, Ji-Yuan Liu, Guo-Zhu Ning

The simplest type III seesaw model as originally proposed introduces one lepton triplet. It thus contains four active neutrinos, two massive and two massless at tree level. We dete…

Radiative and leptonic decays of the pseudoscalar charmonium state $η_{c}$

Mao-Zhi Yang

The radiative and leptonic decays of $η_{c} \to γ γ$ and $η_{c} \to l^{+} l^{-}$ are studied. For $η_{c} \to γ γ$ decay, the second-order electromagnetic tree-level diagram gives the leading contr…

The puzzle of excessive non- $D D ˉ$ component of the inclusive $ψ (3770)$ decay and the long-distant contribution

Xiang Liu, Bo Zhang, Xue-Qian Li

In this letter we suggest that the obvious discrepancy between theoretical prediction on the $non - D D ˉ$ decays of $ψ (3770)$ and data is to be alleviated by taking final…
