Physics Today Q&A with Chris Quigg, Author of Gauge Theories of the Strong, Weak, and Electromagnetic Interactions

quigg2In the July 2014 edition of Physics Today, Princeton University Press author Chris Quigg sits down with Stephen Blau and Jermey Matthews to talk particle physics and gauge theories.

A member of the Theoretical Physics Department of the Fermi National Accelerator Laboratory, Mr. Quigg also received the American Physical Society’s 2011 J. J. Sakurai Prize for outstanding achievement in particle theory. His books include Gauge Theories of the Strong, Weak, and Electromagnetic Interactions (2013) and the 1993 edition of the Annual Review of Nuclear and Particle Science.

The following questions have been excerpted from Physics Today:

PT: What is your assessment of the current state of particle physics, including the quality and enthusiasm of current students? With the excitement over the Higgs and other advances, are you concerned that the field might be overhyped?

Quigg: It is an immensely exciting time. In common with many areas of physics and astronomy, particle physics has many challenging questions and the means to address them. Our students and postdocs are highly motivated, talented, and intensely curious. It’s a test for our institutions, including funding agencies, to create rewarding career paths for the young people drawn to science by the excitement of our work.

When I was hiking in Europe in the weeks before the Higgs discovery was announced, it seemed that everyone I met wanted to know what was happening [at the LHC] in Geneva. Sharing our explorations with the public is good for science and good for society.

“Sharing our explorations with the public is good for science and good for society.”

PT: What are the most exciting questions you see the particle-physics community answering in the short term, say within 10 years?

Quigg: I close the new edition of Gauge Theories with a list of 20 outstanding questions—many with multiple parts—and 1 great meta-question: How are we prisoners of conventional thinking?

Within 10 years we will certainly have a much more complete understanding of electroweak symmetry breaking and the character of the Higgs boson. The initial LHC results have shaken theorists out of a certain complacency; specifically, a lot of received wisdom about naturalness and supersymmetry is being reexamined. Searches for dark matter are reaching a decisive stage. Studies of processes that are highly suppressed in the standard model, such as lepton-flavor violation, flavor-changing neutral currents, and permanent electric dipole moments, will reach ever more interesting levels of sensitivity. A world with massive neutrinos poses questions about the nature of neutrino mixing, the existence of sterile neutrinos, and the character of the neutrino—is it a Dirac particle, a Majorana particle, or both? I suspect that we will find new phenomena in the strong interactions that teach us about the great richness of QCD.
