Sally Dawson of Brookhaven National Laboratory, the current Ben Lee fellow in the Fermilab Theory Department, will present this afternoon’s colloquium, “What Is the Energy Scale Beyond 1 TeV?”

Much in demand as a lecturer at conferences and summer schools around the world and co-author of the celebrated “Higgs Hunter’s Guide,” Sally will focus on the importance of understanding the properties of the Higgs boson, specifically its couplings to fermions and gauge bosons. She will consider, in the context of various conjectures for new physics at high-energy scales, how well we need to measure the Higgs-boson couplings.

After receiving her Ph.D. from Harvard in 1981, Sally began her career as a Fermilab postdoc. While here, she co-authored influential articles on the search for supersymmetric particles and on the production of heavy quarks in hadron-hadron collisions. During a second postdoctoral appointment at Lawrence Berkeley National Laboratory, she helped uncover the importance of vector boson fusion for Higgs boson production.

She moved in 1986 to Brookhaven, where she has made many notable contributions to the phenomenology of electroweak symmetry breaking and the search for phenomena beyond the Standard Model, including numerous calculations important for the interpretation of data from the Tevatron and Large Hadron Collider.

Dawson has led the Brookhaven theory group and chaired the Physics Department. She now serves as adjunct professor at Stony Brook University. Her extensive community service includes chairing the Fermilab Physics Advisory Committee and the Division of Particles and Fields of the American Physical Society, as well as serving as vice chair of the EPP2010 committee of the National Research Council. She is a fellow of the APS and the American Association for the Advancement of Science.

The Ben Lee Fellowship, successor to the Fermilab Frontier Fellows program, brings distinguished senior theorists to Fermilab to contribute to and profit from the intellectual life of the laboratory. The fellowship honors the memory of Benjamin W. Lee, one of the world’s leading theorists, who led the theory group from 1973 until his tragic death in an auto accident in 1977.
