Abstract
These are excerpts from the closing talk at the "XIIth Conference on Quark Confinement and the Hadron Spectrum", which took place last Summer in Thessaloniki --an excellent place to enjoy an interest in archeology. A more complete personal view of the early days of QCD and the rest of the Standard Model is given in [1]. Here I discuss a few of the points which --to my judgement-- illustrate well the QCD evolution (in time), both from a scientific and a sociological point of view.
Highlights
As one could judge from many talks at this conference [2], two areas of QCD have witnessed an enormous progress over the years
The official history is that they were invented by Gell-Mann and Zweig, in that chronological order: Gell-Mann’s published paper was received by Physics Letters on January 4th 1964, while Zweig’s unpublished work is a CERN yellow report dated January 17th of the same year
I was asked at this conference whether Bloom–Gilman duality (BGD) is a prediction of QCD
Summary
As one could judge from many talks at this conference [2], two areas of QCD have witnessed an enormous progress over the years. One of them is the non-perturbative first-principle lattice calculation of many relevant observables. The other embodies the next-to-next-to...leading-order results for many observed processes. How do some of these results compare with the corresponding earliest ones? How have the attitude and perceptions of “the community” evolved with time? How do some of these results compare with the corresponding earliest ones? How have the attitude and perceptions of “the community” evolved with time?
