1) has systematically studied the neutral flow coupling effect of supersymmetric new particles in photon collision physics, the strong CP destruction of heavy quarks and the taste change. It is proved that photon collision has irreplaceable advantages in many frontier topics of particle physics. This conclusion strongly supports the physical idea of building a linear photon collider. This part of the research published 18 papers and was cited 14 1 times. Because of his outstanding achievements in the research of photon collision physics, he was invited to attend the 7th International Conference of High Energy Photon Collider in 2000, and made a special report on the detection physics beyond Sm on the gamma collider, and became the co-author of the physics part of Tesla's photon collision demonstration, drafting the summary report of Tesla's photon collider. This report was adopted by DESY Institute's TESLA linear collider design report as a physical demonstration to support the realization of photon collision mode on the next generation linear collider.
2) The cross sections of supersymmetric particles such as Higgs, Neutrolio/Chargino in the High Energy Hadron Collider are calculated accurately, which provides a theoretical basis for Tevatron and future LHC experiments to find new physics. * * * Published papers 1 1, cited 67 times. From June, 5438 to October, 2000 10, his research interest expanded to the research of high-energy particle experimental physics, and he participated in the Tevatron-D0 international cooperation group of Fermi National Laboratory as a researcher in the Department of Astronomy and Physics of Manchester University.
3) In the aspect of detector research, it is responsible for the design of Run2b upgrade scheme for the first-level center trajectory trigger system L 1CTT of D0 detector. After the brightness of Tevatron Run2b high-energy proton-antiproton collision is upgraded, the original Run2a trigger system will not work, resulting in the physical signal being completely submerged by the QCD background. The new Run2b scheme will increase the background resistance of L 1CTT system by an order of magnitude on the basis of Run2a. The new Run2b scheme has passed the DOE technical appraisal, and has become the blueprint for upgrading the L 1CTT trigger system, and entered the technical debugging stage. I will continue to be responsible for improving and upgrading this plan. The research and development of L 1CTT Run2b is considered as a significant contribution to the entire D0 cooperation group. Published 2 papers, including the Design Report of Run IIB Upgrade Technology submitted by D0 Cooperation Group to DOE, and was responsible for drafting the Level 1 tracking trigger. 4) In the aspect of D0 physical analysis, an experimental method is proposed to identify the final state of double τ by using the multiplied time-life information. This method is being tested and developed on D0 data. If it is proved to be effective, it will provide a powerful new means for the generation analysis of τ lepton pairs in the Hadron Collider, and play an important role in the search for neutral and singular Higgs particles and other physical events. In June 2004, the "Hundred Talents Program" of China Academy of Sciences was introduced, and a professor from the Department of Modern Physics of the University of Science and Technology of China was specially invited. Now he is responsible for the establishment of HKUST D0 experimental physics group and the construction of international high-energy data SAM Grid grid system.
