Title: Charged bottomoniumlike structures in the hidden-bottom dipion decays of {Upsilon}(11020)

Abstract

Under the Initial Single Pion Emission mechanism, we study the hidden-bottom dipion decays of {Upsilon}(11020), i.e., {Upsilon}(11020){yields}{Upsilon}(nS){pi}{sup +}{pi}{sup -} (n=1, 2, 3) and {Upsilon}(11020){yields}h{sub b}(mP){pi}{sup +}{pi}{sup -} (m=1, 2). We predict explicit sharp peak structures close to the BB* and B*B* thresholds and their reflections in the {Upsilon}(1S){pi}{sup +}, {Upsilon}(2S){pi}{sup +} and h{sub b}(1P){pi}{sup +} invariant mass spectrum distributions. We suggest that a future experiment, i.e., Belle, BABAR, and forthcoming BelleII or Super-B, carry out the search for these novel phenomena, which can provide important tests to the Initial Single Emission mechanism existing in higher bottomonia.
