演講題目 CERN's discovery of the Higgs Boson: Back to the Origin of the Universe
摘要 The Large Hadron Collider (LHC) is a gigantic scientific instrument currently in operation at CERN (Geneva). It is a particle accelerator designed to look for a solution to some of the most important open questions of modern physics: the origin of mass, the nature of dark matter that keeps together galaxies in the universe, the issue of the unification of the fundamental interactions. The answer to some of these questions could change in depth our current vision of matter and of the origin of the universe. The actual status of the studies at LHC will be presented with a special attention to the recent discovery of the Higgs boson.<br /> <br /> The Higgs boson is an unstable particle, living for only the tiniest fraction of a second but it plays a major role in particle physics and in shaping the cosmos. The particle can be seen as a manifestation of an invisible field that fills every corner of our universe assigning a distinctive mass to each elementary particle. As a consequence of the mechanism, the chaotic ingredients of the early universe, at a certain moment, started eventually to attract one another and clump into atoms, gas, galaxies, planets and people.<br /> <br /> We'll present the major steps that led to this historical discovery and discuss briefly its possible implications for a deeper understanding of nature.<br /> <br /> <b>Acknowledgement</b><br /> <br /> For the lecture being shared on this site, we owe gratitudes for permission given by the Center for the Advancement of Science Education (CASE) at National Taiwan University.
