Ann Heinson is an American high-energy particle physicist known for her work on single top quark physics. She established and led the DØ Single Top Group which first published experimental observations of the top quark,[1] and in 1997 she co-authored a paper which laid the foundations for further investigation into the top quark.[2]
Heinson grew up in Billericay, S.E. England. She earned both her B.Sc. in Physics (1984) and Ph.D. in High Energy Physics (1988, advisor Peter Dornan) from Imperial College.[3]
Heinson worked for the BBC's engineering research department before emigrating to California in 1989. There, she worked as a postdoctoral researcher at UC Irvine on a rare kaon decay experiment E791 at Brookhaven National Laboratory. In 1992, she began working on the DØ collaboration at Fermi National Accelerator Laboratory. She established and led the DØ Single Top working group from 1995 to 2009.[3] In 1997, she co-authored the paper "Single Top Quarks at the Fermilab Tevatron," which laid the conceptual foundations for the next decade of top quark experimental research.[2] The observation of the production of single top quarks resulted from proton-antiproton collisions measured by the DZero detector which is the world's highest-energy particle collider. Under her leadership, the single top working group discovered the first evidence of single top quark production at Fermi Labs Tevatron. She retired in 2012.[3]
