Although claiming to be far from the whirlpool of public opinion, Gao Yuanning, director of the High Energy Physics Research Center of Tsinghua University who is attending a conference in the United States, has been paying attention to the controversy surrounding the Super Large Collider in recent days. Domestic scientists want to build a large collider "ring positive and negative electron collider (CEPC)." "How CEPC did it and how much it cost, we've done a lot of argumentation on these aspects and completed the preliminary concept design report, but as far as I can observe, very few people have seen it, and even some industry insiders who participated in the discussion have not seen it." Plateau On the 8th, when interviewed by Science and Technology Daily, it was clearly believed that the construction of a ring-shaped electron-positron collider at this stage and the further study of the Higgs particle are the necessary stages of the development of high-energy physics. "Fundamentals of Physics therefore face an important turning point and an opportunity for growth." Kohara prefers to say that it's like a jigsaw puzzles, you have completed a puzzle and want to start a new one, where did you start? "The new physics theory is not without, but too much, the development of high-energy physics to the very critical time, the need for experiments to give a direction." Scientists began to discuss where basic physics will be developed. Several hypotheses of accelerator-based high-energy cutting-edge experimental devices have emerged internationally. In the meantime, the Chinese high-energy physics community has been pondering the question of how to proceed with the existing Beijing Electron-Positron Collider (BEPC). Heights rather said that the Chinese Physics Society subordinate high-energy physics organized several strategic discussions, but has not been identified the right direction. "At that time, some people said that Japan is already doing a linear collider, and we can no longer do the same thing, but we can not directly make a proton collider, so our technical and talent teams can not keep up." Higgs particle until the discovery. "In fact, as early as the end of 2011, there are already some signs that the Higgs particle may be very light. At that time we realized that the cyclone might have a chance because it had the advantage of producing a large number of Higgs particles and studying it accurately Physics of the energy area. "Highland says. Institute of High Energy Physics, Chinese Academy of Sciences researcher Zhang Chuang also told reporters that science and technology, high-energy physics branch of the Organization of the final consensus on strategic research, will give priority to the development of CEPC. "CEPC can be regarded as the consensus of China's high-energy physics community.Wang Yifang, director of Institute of High Energy Physics, Chinese Academy of Sciences, wants longer term and proposes not to block the development of Super Proton Collider (SPPC) while designing and constructing CEPC." Plateau rather said. After many discussions, especially at Xiangshan meeting in June 2013, the idea of ​​constructing CEPC + SPPC was supported by the domestic high-energy physics community. "First of all, I do not know where the cost of the LZs is lower than that of the RCDs. It is internationally recognized that ILCs are much more expensive than CEPCs. Which of CEPC and ILC first got the best Higgs particles The result of the measurement is exactly which one of the projects was approved first and completed first. This competition is just an indication of the importance of building the Higgs particle plant. " Zhang Chuang said that ILC and CEPC resemble Higgs particle research content, but ILC is a linear collider, the newly discovered Higgs particle quality is relatively low, the use of CEPC ring positive and negative electron collider It will be more cost-effective and performance-enhancing, and it will be possible to build an extra-powerful Hadron Collider in the same toroidal tunnel. LHC is a Hadron Collider, collisions produced secondary particles out of the image is more complex, far less electron collider mapping so clear, CEPC as a ring positive and negative electron collider can Higgs particle Nature of a more in-depth, more accurate research.
