Explore the concept of naturalness in Quantum Field Theory (QFT) following the Large Hadron Collider (LHC) experiments in this 32-minute lecture. Delve into the first part of a five-part series presented by R.T. D'Agnolo, examining the implications of LHC findings on our understanding of QFT naturalness. Gain insights into the latest developments in particle physics and the ongoing quest to reconcile theoretical predictions with experimental results.
