A mini-review of J/ψ and ψ(2S) rare decays in the BES-III experiment has been done. With one year’s luminosity data, about 10 billion J/ψ and 3 billion ψ(2S) decays can be collected at BESIII experiment. The searches of weak decay, LFV decay, C or...

Mini-review of rare charmonium decays at BESIII

Recently, LHCb experiment announced a 3.5$\sigma$ evidence for direct CP violation in $D^0$ decay by looking at the difference between $A_{CP}(D^0\...

We calculate the branching ratios of three pure annihilation type decays in the perturbative QCD approach. The predicted branching ratios are Br(B0→D−sK∗+2)∼6×10−5, Br(Bs→¯D0a02)∼1×10−6 and Br(Bs→D−a+2)∼2×10−6. They are sizable and large enough to...
