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.

1994
New phenomena in the Te V region
Simplest answer: one real scalar field h
Recent CDF measurement 7sigma off:
LHC precision programme
Observable Experiment
The LHC has revolutionized our views on the particle world.
Wrong statements
Naturalness
Higgs mass
1 Scale separation
2 EFT validity Naturalness:
Could it be that the rules of EFT break down?
Some theories allowed by EFT symmetries live in the swamp land
IR/UV correlation
IR/UV correlation Cohen-Kaplan-Nelson bound
2 EFT validity
Can we give up hypothesis 3?
A radical change in perspective,
Giving up naturalness by relaxing one of its hypotheses often IcTs- TIFR consequences that are even more radical than those of naturalness itself.
Symmetry paradigm
Is the "symmetry paradigm" crumbling down?
The decline of symmetry?
New emerging concepts? Duality: new faces of reality neither language of dual theory captures reality
Naturalness of the cosmological constant
The multiverse
The message from string theory and cosmology
Is the multiverse so odd?
Is the multiverse non-scientific?
Symmetry paradigm - A new paradigm?
Axion
DYNAMICAL RELAXATION MODELS
