Abstract
We discuss the possibility that production of final states with bottomonium and light mesons at the peak (6S) in the e+e- annihilation at approximately 11.00 GeV is in fact due to a triangular singularity at the threshold of the heavy meson pair production B1(5721)B+c.c. through the process e+e-→B1(5721)Bs→Zb(10610)π. The presence of the hidden-bottom resonance Zb(10610) then explains the observed enhanced production of the final channels with both ortho- and para-bottomonium states, (nS)ππ and hb(kP)ππ. The discussed mechanism also predicts a distinct pattern for production of hidden-bottom states at the (6S) energy that can be tested by experiment.
