New Experimental Tests of QCD Symmetries In Pion Physics
Aron Bernstein (MIT)
TIME: 4:00pm, Tuesday, 24 April 2012
PLACE: Corcoran Hall, Room 101
The pi meson plays a central role in physics as the carrier of the long range part of the nucleon-nucleon interaction and as the manifestation of the hidden chiral symmetry of QCD. Several examples of new, sensitive experimental tests will be presented including pion photo-and electro-production. These test predictions based on spontaneous chiral symmetry breaking including small isospin breaking effects due to the mass difference of the up and down quarks. A new measurement of the lifetime of the neutral pi meson will be presented. This decay amplitude is dominated by the axial anomaly of QCD, modified by a small isospin breaking chiral correction.

Of all human maladies, cancer remains the most recalcitrant. In spite of vast amounts of monies spent, the over-all mortality rate for the past 40 years has been basically flat. To this day, the best defense has remained early detection followed by surgical removal. Often, by the time symptoms appear it is too late because the tumor has metastasized and become inoperable. Chemotherapy, basically the administration of poisons designed to kill rapidly growing cells, typically wins remission for a period of time but unfortunately also typically fails because the tumor cells evolve resistance to chemotherapy.
Recently, the National Cancer Institute has called for help from the physical sciences to help understand cancer and discover ways to treat it. My own view as a physicist is that we have to entirely rethink cancer as being not a disease but rather perhaps the inevitable result of the rapid evolution of the homo sapiens species. I will examine the roots of evolution as viewed from a more modern form of Darwinian natural selection, and present some experiments that indicate that evolution, and cancer, are inevitably linked together.
About the Speaker:
Bob Austin leads a research group based in the physics department of Princeton University. His research focuses primarily on the use of microarrays and nanotechnology to further our physical understanding of biological processes, such as the dynamics of cells when subjected to stress. The ultimate goal of his research is to understand, and possibly guide, the evolution of microrganisms by culturing them inside custom-made micro-environments. Professor Austin is a Fellow of the American Physical Society, a Fellow of the American Association for the Advancement of Science, and was elected a member of the National Academy of Sciences, USA.
About the Lecture Series:
In 2011 The Barry Berman Memorial Lecture Series was created by a generous gift by one of his dear collaborators and colleagues, Professor Cedric Yu, a faculty member at the University of Maryland School of Medicine, Department of Radiation Oncology. Professors Berman and Yu began collaborating in 2009 on an NIH funded project on dose-rate regulated tracking. The goal of the lecture series is to inspire young people to study medical applications of physics by inviting nationally and internationally prominent scientists to speak on applying physics principles to medicine.

M_n – M_p

TIME: 2:00pm, Thursday, 19 April 2012
PLACE: Corcoran Hall, Room 104
The neutron – proton mass splitting plays a significant role in early stages of the evolution of the universe. Small adjustments of quark masses or electromagnetic coupling lead to significant variations of the neutron lifetime and the primordial abundance of hydrogen, helium and other light nuclei. In the Standard Model, there are two sources for this isospin breaking: the light quark mass splitting and the electromagnetic coupling to the up and down quarks. We provide a modern, robust determination of the electromagnetic self-energy correction to M_p – M_n, drawing attention to the connection to the isovector magnetic polarizability.
Physics Graduate Curriculum
The GW Physics Graduate Curriculum was presented in the symposium “Goals and Assessment of the Physics Graduate Program”of the American Physical Society’s April meeting in Atlanta. The session was devoted to hear if the “standard” curriculum of most US universities needs to be changed because of: (1) a wide gap between 50-year-old curricula and the proficiencies expected to start research; (2) a high attrition rates and long times to degree; (3) limited resources in small departments to cover all topics deemed essential. What are the objectives of a graduate education in physics? Participating in a panel of invited experts, Dr. Griesshammer (Physics Graduate Advisor) showed how the dissatisfaction of both student and faculty led to significant re-structuring at GW in 2009.
