Charged bottomoniumlike structures in the hidden-bottom dipion decays of Y(11020)

Under the Initial Single Pion Emission mechanism, we study the hidden-bottom dipion decays of Y(11020), i.e., Y(11020) -> Y(nS)pi(+)pi(-) (n = 1, 2, 3) and Y(11020) -> h(b)(mP)pi(+)pi(-) (m = 1, 2). We predict explicit sharp peak structures close to the B (B) over bar* and B*(B) over bar* thresholds and their reflections in the Y(1S)pi(+), Y(2S)pi(+) and h(b)(1P)pi(+) 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.
