We report results on studies of the e+e− annihilation into three-body ϒ(nS)π+π− (n=1,2,3) final states including measurements of cross sections and the full amplitude analysis. The cross sections measured at s=10.866 GeV and corrected for the

We report the analysis of the three-body e+e- => B B-bar pi, B B*-bar pi, and B* B*-bar pi processes, including the first observation of the Zb+-(10610) =>[B B*-bar+c.c.]+- and Zb+-(10650) => [B*B*-bar]+- transitions. We measure visible cross section

We review the recent results from the Belle experiment: search for new physics in $B \to \tau \nu$ and related decays, study of charged bottomonium-like states $Z_b$ and measurement of the parameters of the Cabibbo-Kobayashi-Maskawa matrix in $B^0\to

Confirming the molecular nature of the $Z_b(10610)$ and the $Z_b(10650)$

Autor: Cleven, Martin, Wang, Qian, Guo, Feng-Kun, Hanhart, Christoph, Meißner, Ulf-G., Zhao, Qiang

Publikováno v: Physical review / D 87(7), 074006 (2013). doi:10.1103/PhysRevD.87.074006

The decays of the $Z_b(10610)$ and the $Z_b(10650)$ to $\Upsilon(nS)\pi$, $h_b(mP)\pi$ and $\chi_{bJ}(mP)\gamma$ ($n=1,2,3$, $m=1,2$ and $J=0,1,2$) are investigated within a nonrelativistic effective field theory. It is argued that, while the decays

Bound state nature of the exotic Z_b states

Autor: Martin Cleven, Ulf-G. Meißner, Feng-Kun Guo, Christoph Hanhart

Publikováno v: The European physical journal / A 47, 120 (2011). doi:10.1140/epja/i2011-11120-6

The assumption that the newly observed charged bottomonia states Z_b(10610) and Z_b(10650) are of molecular nature is confronted with the measured invariant mass distributions for the transitions of the Upsilon(5S) to the final states h_b pi^+ pi^- a
