Title: Radiative and ρ transitions between a heavy quarkonium and isovector four-quark states

Abstract

The recent observation and measurement of the decay Z c (3900) → ρη c provides the data on the relative strength of the pion and ρ coupling in the corresponding transitions between exotic resonances and pure heavy quarkonium. It is argued that using these data, the heavy quark limit for the c and b quarks, the heavy quark spin symmetry (HQSS) and the vector dominance for photon emission by the light quarks, one can (approximately) quantitatively estimate the rates of the radiative transitions from Υ(5S) to the expected G-odd states of molecular bottomonium W bJ. The estimate of the cross section of the processes e +e - → γW bJ at the maximum of the Υ(5S) resonance comes out in the ballpark of 0.1 pb, which sets a benchmark for a possible search for these processes at BelleII.
