Search for $D^{0} \to γ γ$ and improved measurement of the branching fraction for $D^{0} \to π^{0} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +412

Using $2.92$ fb $^{- 1}$ of electron-positron annihilation data collected at $s = 3.773$ ~GeV with the BESIII detector, we report the results of a search for the flavor-changin…

The $B_{c} \to ψ (2 S) π$ , $η_{c} (2 S) π$ decays in the perturbative QCD approach

Zhou Rui, Wen-Fei Wang, Guang-xin Wang +2

Nonleptonic two body $B_{c}$ decays including radially excited $ψ (2 S)$ or $η_{c} (2 S)$ mesons in the final state are studied using the perturbative QCD approach based on $k_{T}$ factoriza…
