Research Project
I am a legal member of the BESIII Collaboration. BESIII is a symmetry e+e- collider experiment covering c.m energy 2 GeV to 4.6 GeV, and has accumulated world's largest charmonium/charmoniumlike data sample. I am studying conventional charmonium decays, and hunting new XYZ particles at BESIII. In 2013, I have discovered a charged charmoniumlike state Zc(3900), which might be the first four quark state with solid evidence. In addition, I also have a wide range study on X(3872), Y(4260)...
Marie Curie Fellow (European Commission)
I am a Marie Curie Fellow (IIF) hosted at Mainz University. This fellowship is funded by the European Commission under the Seventh Framework Programme (FP7).
I am a legal member of the Belle Collaboration. Belle is an asymmetry e+e- collider experiment running @ Y(nS) (n=1,2,...,5). Belle has accumulated ~1000fb^-1 data, which is world's largest data sample. I am searching for extoic states from Initial-State-Radiation (ISR) process and two-photon production. I give the first measurement for gamma gamma to vector meson pairs cross section. Using Belle's full data set, I found a charged charmoniumlike state Z(3900) in Y(4260) decays.
I joined the PANDA Collaboration in 2013 and extended my hadron spectroscopy program in an anti-proton proton experiment.

Travel & Activities
a). 23th June to 2nd July, 2012, Erice, Sicily. It's an interesting travel.
Take a photo with Prof. Peter Ware HIGGS, the Nobel Prize Winner for Physics in 2013 (2013年诺贝尔物理学奖得主).
I was awarded “Chien Shiung WU” Diploma by Prof. Gerardus ’t Hooft and Prof. Antonino Zichichi.
b). I was invited to the 66th Lindau Nobel Laureate Meeting in Lindau, Germany (June 26th - July 1st, 2016).
