W.K.H. Panofsky Prize in Experimental Particle Physics: Tracking the perfect incompleteness of the Standard Model across five decades

In 1970, the body of knowledge known as the Standard Model (SM) of particle physics was just coming together. In the five decades since then, there have been many precise predictions, sharpened by improvements in theoretical calculations and new techniques such as Lattice Gauge Theory. Despite massive effort, no inconsistencies have been found  between

the SM and experiments. Within its domain of applicability, the SM has proven to be "perfect". Nevertheless, as good as it is in describing the weak, electromagnetic, and strong interactions of its six flavors of quarks and three flavors of leptons, spanning more than nine orders of magnitude in mass, the SM is "incomplete". It does not explain the matter- antimatter asymmetry of our universe, dark matter and dark energy,  the small masses of the three flavors of neutrinos, why the mass of the Higgs Boson  is stable against vacuum fluctuations, or gracefully incorporate the gravitational interaction. There are many arbitrary parameters, most of which are associated with the masses and mixing of quarks and leptons. This contribution will cover some of the experiments during this period that have studied heavy flavor production and decays and SM measurements of the Higgs coupling to heavy quarks and leptons, hoping to find some indication of physics beyond the Standard Model (BSM). High-precision studies of decays involving neutral currents, quark mixing and CP violation, and lepton flavor universality violation have all been studied recently. Powerful theoretical frameworks have been employed to look for emergent patterns across several studies. Prospects for pushing onward in experiments in the next decade are discussed briefly. We still  hope to find a dent or crack, some discrepancy or deviation, between the apparent perfection of the SM and experiment or some new phenomena from a weakly-coupled hidden sector that will shatter its "perfect incompleteness" and help address the questions for which it currently has no answers.
