High Energy Physics (2020)

Program: January 6-24, 2020
Conference: January 20-22, 2020

After the discovery of the Higgs boson, the main objectives of high-energy physics are the precise measurement of Higgs properties and searches for new physics. These objectives strongly motivate the construction of an e+e- Higgs factory and a new pp collider with energy significantly higher than that of the Large Hadron Collider (LHC).

The Higgs boson plays a crucial role in explaining spontaneous electroweak symmetry breaking and the mass generation of the known fundamental particles. It is thus important to measure precisely the Higgs-gauge couplings, the Higgs-Yukawa couplings and the Higgs self-couplings. A future Higgs factory would achieve such a goal significantly better than the LHC. Such precise measurements also provide an indirect probe for new physics that alters the Higgs properties.

Addressing fundamental puzzles in nature such as hierarchy problem, dark matter, etc. results in expectation that new physics should emerge at the TeV scale or above. A higher energy pp collider will be crucial for directly exploring new physics and the properties of any to-be-discovered particles at the LHC.

This High Energy Physics (HEP) program in Hong Kong started in 2015. The objective of this program is to bring theorists, experimentalists and accelerator physicists together, and to facilitate stimulating discussion among participants. Issues on the physics, detectors and colliders with an emphasis on the future of high energy physics will be addressed. As part of the program, a four-day conference will be held during January 20-22, 2020. Before that, three two-day mini-workshops will be organized, focusing on theory (January 9-10), experiment/detector (January 16-17) and accelerator physics (January 16-17), respectively. It is also hoped that some white papers for the particle physics community documenting the physics goals, options of future colliders, and the reach of the related experiments could be released.
