Abstract

For the last 20 years of his remarkable career, Jack Sandweiss was an enthusiastic leader in heavy-ion physics, especially excited about two main topics: the search for stable or metastable strange quark matter and the possibility of local parity violation in heavy-ion collisions. I take a look back at some of Jack’s contributions in the context of the current state of both of these very active areas.

Highlights

Jack’s graduate studies were done at the rad lab in Berkeley, and he started out right in the thick of particle physics, where he worked in one of the groups searching for the antiproton, and though their technique didn’t win the race due to the unexpectedly large annihilation cross-section, they were able to make one of the first measurements of that cross section [1]
He did a bit of work [2] that contributed to the understanding of the "τ − θ" kaon puzzle that helped lead to the discovery of weak parity violation
The bremstrahlung experiment didn’t go forward at RHIC, bit it has recently seen renewed interest at LHC energy [14]. Though he worked on other topics in heavy-ions, his main interest started with the 1998 paper [15] suggesting that parity and CP symmetries might be broken "locally" in regions generated in heavy-ion collisions

Summary

Jack’s early career

It was an honor for me to be able to give this talk remembering Jack Sandweiss at the SQM ’21 conference. Jack’s graduate studies were done at the rad lab in Berkeley, and he started out right in the thick of particle physics, where he worked in one of the groups searching for the antiproton, and though their technique didn’t win the race due to the unexpectedly large annihilation cross-section, they were able to make one of the first measurements of that cross section [1] He did a bit of work [2] that contributed to the understanding of the "τ − θ" kaon puzzle that helped lead to the discovery of weak parity violation. He became an eminently respected physicist; helping to steer the field by chairing the HEPAP advisory panel in the 80s, and succeeding his friend Bob Adair as chief editor of Physical Review Letters through the 90s and 2000s
