SSE Special Colloquium | 理工学院系列研讨会邀请

The School of Science and Engineering is committed to creating a platform for students and faculty members to exchange ideas and explore cutting-edge research developments in various fields of science and engineering. Starting from 2021 fall, SSE will organize the "Weekly Colloquium" series of seminars every Friday. Each week, SSE will invite our faculty members and distinguished guest speakers from outside the University to conduct academic seminars.  

All students and faculty members are invited to join the weekly colloquium!

Abstract

What is the Dark Matter, which makes 85% of the matter in the Universe? We have been asking this question for many decades and used a variety of experimental approaches to address it, with detectors on Earth and in space. Yet, the nature of Dark Matter remains a mystery. An answer to this fundamental question will likely come from ongoing and future searches with accelerators, indirect and direct detection experiments and from observations in cosmology and astrophysics. Direct detection of a signal from dark matter particles such as Weakly Interacting Massive Particles (WIMPs) in a terrestrial detector will provide the most direct evidence for their existence. It will be a ground-breaking discovery in physics and cosmology. Among the variety of dark matter detectors, liquid xenon time projection chambers have shown to be the most sensitive, thanks to a combination of very large target mass, ultra-low background, and excellent signal-to-noise discrimination. Experiments based on this technology include the pioneering XENON project which I have led since its inception. In this talk I will review the most recent advances in the field of direct detection.

The Speaker

Elena Aprile holds the distinguished title of Centennial Professor of Physics at Columbia University. She pioneered the XENON project and has been its spokesperson since its inception in 2004. Under her leadership, the XENON Collaboration has developed four cutting-edge generations of liquid xenon experiments, all of which have been at the forefront of dark matter direct detection searches. Prof. Aprile's accolades include the Roma Prize (2023), the Julius Wess Prize (2022), the Enrico Fermi Prize (2021) and the Berkeley-Lancelot Prize (2019). She has been invited to deliver numerous prestigious lectures, such as the Columbia University C.S. Wu Honorary Colloquium, the University of Zurich Schrödinger Colloquium, the Yale University Vernon Hughes Colloquium, the Oxford University Cherwell-Simon Memorial Lecture, the Princeton University Hamilton Honorary Lecture, and the Simons Foundation Della Pietra Lecture, among others. She is a member of the United States National Academy of Sciences and of the American Academy of Arts and Sciences and was honored with the medal of Ufficiale della Republica Italiana by Italian President Carlo Azeglio Ciampi. In recognition of her contributions, the asteroid 268686 Elenaaprile, discovered by Italian amateur astronomer Silvano Casulli in 2006, was named in her honor.
