内容摘要：In this seminar, I would like to cover two topics: (i) Recent progress on the search for the QCD critical point with the beam energy scan program at RHIC and future plans; (ii) Lambda polarization has been observed experimentally more than 50 years, yet its origin remains unknown. Here, we will discuss some of the early measurements and a newly proposed state-of-the-art spectrometer, Hyperon-Nucleon Spectrometer (HNS), aimed to study the Lambda polarization systematically with energy scan of p-p, p-A, A-A collisions at HIAF. Potential measurements for other physics program with the HNS will also be discussed.
