Abstract

The High-Intensity heavy-ion Accelerator Facility (HIAF) is about to be finished with construction. It will be able to provide proton and heavy-ion beams with several GeV energies, providing good opportunities for a wide range of physical research, including the search for new particles and new interactions beyond the standard model, the verification of basic symmetries such as the CP symmetry, the search for new (exotic) hadron states, exotic di-baryons and new (multi-strange) hypernuclei, precise measurement of hadron and hypernucleus properties, the search and location of the nuclear matter phase boundary and the critical point, etc. We plan to build an experimental spectrometer consisting of a solenoid magnet, a silicon pixel tracker, an LGAD time-of-flight detector, and a Cherenkov-scintillation dual-readout electromagnetic calorimeter at the HIAF high energy terminal, to achieve a large acceptance, an extremely high event rate of 1MHz-100MHz, a multi-particle identification capability, and a high position resolution of tens of microns. This spectrometer will be capable for the above-mentioned physical researches and will promote the development of medium- and high-energy particle physics and nuclear physics researches based on facilities in China. This report will introduce the conceptual design of the experiment and preliminary simulation results.

Biography

Dr. Qiu Hao is a scientist at the Institute of Modern Physics, Chinese Academy of Sciences, head of the Nuclear Matter Phase Structure Group, deputy director of the Key Laboratory of Heavy Ion Science and Technology, head of a CAS Project for Young Scientists in Basic Research and a council member of the Chinese Nuclear Physics Society. Dr Qiu has a rich experience in experimental research in relativistic heavy ion collisions, participated in the STAR experiment at RHIC, the CMS experiment at LHC, and the development of the CEE experiment at HIRFL. He served as the deputy chief engineer of the CEE scientific application system. At the same time, he is organizing the development of a novel neutrinoless double-beta decay experiment called NvDEx. He led or participated in the discovery of three new antimatter particles, among which the discovery of the anti-hypertriton was one of the top ten yearly scientific advances in China, and the anti-hyperhydrogen-4 is the heaviest anti-hypernucleus discovered so far. He has published more than ten papers in top academic journals such as Nature, Science, and PRL.
