Women in physics

Interview with Sally Dawson, Senior Scientist at Brookhaven National Laboratory and head of the high energy theory group there. Dawson recounts her childhood in Cleveland where her father was a rocket scientist for NASA. She describes her undergraduate education at Duke and how she came to focus on physics. Dawson cites the formative influence of Howard Georgi during her graduate work on proton decay and precision calculations at Harvard. She discusses her postdoctoral research in the theory group at Fermilab and her focus on some of the theoretical implications of the Tevatron project. Dawson surveys the research on supersymmetry and the Higgs mass at that time, and she explains her decision to join the scientific staff at Brookhaven where Mike Creutz and Bill Marciano were doing research of interest to her. Dawson discusses her long-term efforts to search for new physics beyond the Standard Model and she describes her book the Higgs Hunter’s Guide. She surveys what is known and unknown about the Higgs boson, and she discusses the g-2 muon experiment at Brookhaven and its relation to the current experiment at Fermilab. Dawson explains the value of the Snowmass process in achieving a high-level and future-oriented view of where the field is headed, and why the discovery of the Higgs demonstrated the overall accuracy of the Standard Model. She surveys the new questions that can be probed following the Higgs discovery and the complementary nature of neutrino precision measurements for this research. At the end of the interview, Dawson discusses her outreach efforts to emphasize that particle theory is not “dead,” why she sees advisory work as a vital service to the field, and why over the course of her career, experimentalists have provided more guidance to theorists, and not vice-versa.

She describes the shutdown period that started in 2013 and the circumstances to her being named Director-General in 2013. Gianotti surveys what has, and has not, been detected at the LHC over the past decade, and how dark matter searches at CERN are complementary to those using Xenon detectors. She conveys optimism about the high luminosity upgrade at the LHC and how she frequently operates in political realms given the international nature of CERN. At the end of the interview, Gianotti observes that current projects at the CERN are reminiscent of the buildup to the LHC, and why this bodes well for the future of experimental particle physics.
