The theory of superstring with flux on non-Kähler manifolds and the complex Monge-Ampère equation
The purpose of this paper is to solve a problem posed by Strominger in constructing smooth models of superstring theory with flux. These are given by non-Kahler manifolds with torsion.

Balanced metrics on non-Kahler Calabi-Yau threefolds
We construct balanced metrics on the family of non-K\"ahler Calabi-Yau threefolds that are obtained by smoothing after contracting $(-1,-1)$-rational curves on K\"ahler Calabi-Yau threefold. As an application, we construct balanced metrics on complex manifolds diffeomorphic to connected sum of $k\geq 2$ copies of $S^3\times S^3$.

Search for dark sector BESIII
With 106M ψ ′ events collected at BESIII detector, there is no observed signal of light Higgs-like boson A 0 in process J/ψ → γA 0 , A 0 → µ + µ − . The A 0 -massdependent upper limits at the 90% C.L. of branching fraction for J/ψ → γA 0 , A 0 → µ + µ − are range from 4 × 10 −7 to 2.1 × 10 −5 , for M(A 0 ) < 3.0 GeV/c 2 . With 225M J/ψ data sample, there is no obseved signal of light dark matter particles or U boson in invisible decays of η and η ′ . The upper limits at the 90% C.L. are determined to be 2.6 × 10 −4 for the ratio B(η→invisible)
