Abstract
Using a data sample corresponding to an integrated luminosity of collected at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider, we search for a scalar partner of the , denoted as , via and processes. No significant signals are observed and the upper limits of the product branching fractions and are determined at the 90% confidence level, for the narrow with a mass ranging from 3710 to , which are from 0.9 to and 0.9 to , respectively.
