N2 - Using a data sample corresponding to an integrated luminosity of 2.93 fb-1 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 X(3872), denoted as X(3700), via ψ(3770)→γηη′ and γπ+π-J/ψ processes. No significant signals are observed and the upper limits of the product branching fractions B(ψ(3770)→γX(3700))·B(X(3700)→ηη′) and B(ψ(3770)→γX(3700))·B(X(3700)→π+π-J/ψ) are determined at the 90% confidence level, for the narrow X(3700) with a mass ranging from 3710 to 3740 MeV/c2, which are from 0.9 to 1.9(×10-5) and 0.9 to 3.4(×10-5), respectively.
