Explore the cutting-edge developments in high-energy particle physics through this comprehensive lecture by renowned physicist Gian Giudice from CERN. Delve into the current state of particle physics and its future aspirations, with a particular focus on the high-energy collider program. Examine the revolutionary impact of the Large Hadron Collider (LHC) on our understanding of the particle world, and critically analyze concepts such as naturalness, effective field theory (EFT), and the symmetry paradigm. Investigate emerging ideas like duality, the multiverse, and dynamical relaxation models. Gain insights into the challenges facing the field, including the naturalness of the Higgs mass and the cosmological constant. Engage with thought-provoking questions about the scientific nature of the multiverse and the potential shift towards new paradigms in particle physics. Conclude with a Q&A session to further explore these complex topics with the expert speaker.
