| Description: |
Utilizing a dataset of 6.7 fb−1 from electron-positron collisions recorded by the BESIII detector at the BEPCII storage ring, a search is conducted for the processes +−→0 and 2(1) across center-of-mass energies from 4.47 to 4.95 GeV. In the absence of any significant signals, upper limits are set. These include limits on the dressed cross sections for +− →0, as well as the product of the dressed cross section for +− →2(1) and a sum of five branching fractions. Furthermore, the product of the electronic width of (4660) and the branching fraction of the (4660) →0, denoted as Γ(4660) +−ℬ(4660)→0, is determined to be |
