N2 - It is argued that the ratio of the yield of pairs of charged and neutral Bmesons in the processes Υ(5S)→π0+(BB *+c.c.) and Υ(5S)→π0+B*B ̄* is very sensitive near the corresponding heavy meson threshold to the strong interaction between the mesons in the IG(JP)=0 -(1 +) channel due to significant isospin breaking by the Coulomb force. This channel, not readily accessible by other means, may contain near-threshold molecular meson-antimeson resonances-isoscalar analogs of the isovector states Z b(10610) and Z b(10650).
