Quantum Field AI on Instagram: "The Standard Model (SM) Lagrangian is a compact mathematical formulation that unifies the electromagnetic, weak, and strong nuclear forces — three of the four known fundamental interactions — along with the matter fields (quarks and leptons) they act upon. It encapsulates a stunningly successful quantum field theory framework built upon gauge symmetries: SU(3)×SU(2)×U(1). This Lagrangian includes all known elementary particles, their interactions via gauge bosons
