Evidence for $e^{+} e^{-} \to γ χ_{c 1, 2}$ at center-of-mass energies from 4.009 to 4.360 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +405

Using data samples collected at center-of-mass energies of $s$ = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a s…

Enhanced breaking of heavy quark spin symmetry

Feng-Kun Guo, Ulf-G. Meißner, Cheng-Ping Shen

Heavy quark spin symmetry is useful to make predictions on ratios of decay or production rates of systems involving heavy quarks. The breaking of spin symmetry is generally of the…
