N2 - Utilizing a dataset of (Formula presented) from electron-positron collisions recorded by the BESIII detector at the BEPCII storage ring, a search is conducted for the processes (Formula presented) and (Formula presented) 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 (Formula presented), as well as the product of the dressed cross section for (Formula presented) and a sum of five branching fractions. Furthermore, the product of the electronic width of (Formula presented) and the branching fraction of the (Formula presented), denoted as (Formula presented), is determined to be (Formula presented) at the 90% confidence level.
