报告题目：Smashing Discoveries——Particle Physics at the High-energy Frontier

报 告 人：Andreas Hoecker 教授（欧洲核子物理研究所CERN）

讲座地点：科大东区物质科研楼三楼报告厅

讲座摘要：The begin of the Large Hadron Collider (LHC) operation at CERN, Switzerland heralded a new era in physics research. The discovery of the Higgs boson by the ATLAS and CMS experiments in 2012 marks a breakthrough in particle physics, and it stands with the greatest scientific discoveries of all time. The Higgs boson is a ripple of a scalar field that gives mass to elementary particles, thereby governing the structure of atoms, molecules, and biological life. The wealth of results obtained by ATLAS and CMS also includes the observation of countless new processes, precision measurements, and the deep and broad exploration of the new physics landscape. The colloquium recalls the foundations of particle physics, introduces the LHC project, presents its most important results, and discusses the remaining open questions and how to address them.

报告人简介：Andreas Hoecker's research in elementary particle physics covers collider physics experiments at CERN and Stanford, USA. He studied physics at Bonn, Germany and earned his PhD at Orsay, France in the 1990s. During that time, he studied the properties of the tau-lepton, the heavy cousin of electron, and strong interactions with the ALEPH and OPAL experiments at CERN's Large Electron-Positron Collider. In 1998 he became Scientist at the French CNRS organization and joined the BABAR experiment at Stanford's National Accelerator Lab (SLAC), where he was responsible for the particle identification device and performed studies of matter-antimatter symmetry violation. Since 2005, he is Research Physicist at CERN and member of the ATLAS experiment. He contributed to the fast online selection, commissioning, and searches for the Higgs boson and Supersymmetry. He served as ATLAS Physics Coordinator in 2014 and 2015, deputy Spokesperson between 2017 and 2021, and was elected ATLAS Spokesperson for the period early 2021 to 2025. Throughout his career, Andreas Hoecker has also worked on particle phenomenology and the development of statistical tools and machine learning.
