Can the hyperfine mass splitting formula in heavy quarkonia be applied to the $B_{c}$ system?

Lei Chang, Muyang Chen, Xue-qian Li +2

The mass relation $M_{0^{+}} + 3 M_{1^{+'}} + 5 M_{2^{+}} = 9 M_{1^{+}}$ miraculously holds for the $P$ -wave charmonium $(c c ˉ)$ and bottomonium $(b b ˉ)$ systems with soarin…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-}$ Cross Section between 600 and 900 MeV Using Initial State Radiation

M. Ablikim, M. N. Achasov, X. C. Ai +398

We extract the $e^{+} e^{-} \to π^{+} π^{-}$ cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated…
