Description:
We study D+s decays to final states involving the η with a 482 pb−1 data sample collected at √s = 4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractionsB(D+s →η

Description:
We report the first observation of the Dalitz decay η′→γe+e−, based on a data sample of 1.31 billion J/ψ events collected with the BESIII detector. The η′ mesons are produced via the J/ψ→γη′ decay pro

Description:
We provide a new insight into the problem of generating the hadron mass spectrum in the framework of the covariant confined quark model. One of the underlying principles of this model is the composite

Description:
The effect of isoscalar S-wave multichannel ππ→ππ, KK¯¯,ηη scattering is considered in the analysis of decay data of the Υ-mesons. We show that when allowing for the final state interaction contributi

Description:
Recently there has been much interest in the tauonic semileptonic meson decays B→D+τ+ντ and B→D∗+τ+ντ, where one has found larger rates than what is predicted by the Standard Model. We analyze the cor
