While the Standard Model is incredibly robust, Veltman and contemporary physicists point to several "mysteries" that suggest we are missing a larger piece of the puzzle: Facts and Mysteries in Elementary Particle Physics
We have confirmed the existence of 17 fundamental particles—12 fermions (matter-builders like quarks and leptons) and 5 bosons (force-carriers like the photon and gluon). Facts and Mysteries in Elementary Particle Physics
Drawing heavily from the insights of Nobel laureate in his celebrated book Facts and Mysteries in Elementary Particle Physics , we can explore the subatomic world through a unique lens: one that separates what we experimentally know for certain (facts) from the profound gaps in our understanding (mysteries). The "Actors" and the "Stage" While the Standard Model is incredibly robust, Veltman
