Unified description of BABAR and Belle data on the bottomonia decays Upsilon(mS) -> Upsilon(nS)pi(+)pi(-)

Popis výsledku v původním jazyce

In this analysis we extend our recent study of low-lying (m = 2, 3) radial excitations of bottomonia to modes involving higher (m = 4, 5) excited states. Similarly as for the data on lower radial excitations, we confirm that the data for higher radiallyexcited states from the BABAR and Belle collaborations can be described under conditions that the final bottomonium is a spectator and the multichannel pi pi scattering is considered in a model-independent approach based on analyticity, unitarity and theuniformization procedure. Indeed we show that the dipion mass distributions in the two-pion transitions of both charmonia and bottomonia states are explained by a unified mechanism based on the contribution of the pi pi and K (K) over bar coupled channels including their interference (final-state interactions). Therefore, our main result is that the lower and higher radially excited states of charmonia and bottomonia have no specific features in mutual comparison and can be understood i
