Abstract
This is a tribute to Jean Letessier, some memories of my PhD research in collaboration with him, a summary of the results we have achieved, and some personal thoughts as to the significance of these results to the field of heavy ion physics as well as the future of our field.
Highlights
Theoretical physics has developed a cult of "assertiveness"
Jean Letessier is a primary counter-example going against this prejudice
Jean and Johann Rafelski made the important realization that, because of the proximity of the mass of the strange quark to ΛQCD strangeness equilibration could function as a “clock”, measuring the degree of chemical equilibration and the global properties of the quark-gluon plasma
Summary
Theoretical physics has developed a cult of "assertiveness". To be noticed, you must be loud, confident, and willing to tell the whole seminar room or conference hall that you are correct and the rest of us do not have a clue. The topic, strangeness enhancement in heavy ion collisions, is one of the pillars of the phenomenology of the quark-gluon plasma phase transition, mainly because of it’s spectacular experimental confirmation [2, 3].
