The Proton Radius Puzzle by Evangeline Downie

Oct 18, 2018, 3:30 PM-4:45 PM

Room: 202/204 Physics Bldg.

Host: Prof. Steven Blusk/ Contact: Yudaisy Salomón Sargentón, 315-443-5960

The Proton Radius Puzzle is the difference between the radius of the proton when measured with electrons, and that measured with muons. Its potential resolutions could be very exciting, include beyond-standard-model physics. Its impact is broad as the uncertainty in the proton radius is the leading cause of uncertainty in many other areas of physics. The puzzle has resulted in several papers in Science and Nature, and much popular media interest. It began in 2010 with an ultra-precise radius measurement by the CREMA collaboration using muonic hydrogen, which produced a proton radius result roughly 7 standard deviations away from the accepted value. This caused a flurry of theory development, new experiments, and much thought and discussion. The radius puzzle remains unresolved to this day, with many new experiments proposed and under development and hotly debated theories. We will give an overview of the Puzzle, its potential implications and resolutions, and an overview of the ongoing experimental efforts to understand the discrepancy in a quantity of relevance for many areas of physics.

Black Holes, and Nuggets, and Blobs. Oh my! -- Andrew Long

The past few years have seen a growing interest to explore dark matter candidates that are outside of the standard WIMP paradigm. A resurgence of macroscopic dark matter candidates have brought with it a mix of whimsical names — primordial black holes, asymmetric dark matter nuggets, and dark blobs — to name a few. In general the difficulty with macro dark matter is not the observational constraints, which are typically quite sparse and weak, but rather the challenge is finding a well-motivated mechanism for producing gram-sized dark matter objects. In this talk, I will argue that “dark quark nuggets” are a generic prediction of confining, hidden-sector gauge theories. I will discuss the phenomenology of these theories, the cosmological production of dark quark nuggets, and their observational probes.

The Kameshwar C. Wali Lecture in the Sciences and Humanities: US Nuclear Weapons Policy: 'Time for the Concerned Public to Intervene Again' by Dr. Frank von Hippel

Nov 29, 2018, 4:00 PM-5:30 PM

SHAFFER ART BLDG AUDITORIUM

Coordinator: Prof. Simon Catterall. Contact: Yudaisy Salomon Sargenton

The last massive intervention by the concerned public in U.S. nuclear weapons policy was by the grassroots Nuclear Weapons Freeze Movement and its European counterpart in the early 1980s. One result was to shift the U.S. government from insisting that the Soviet Union believed it possible to fight and win a nuclear war, and therefore so must we; to repeated joint summit statements by Presidents Gorbachev and Reagan that “nuclear war cannot be won and must never be fought.” More tangibly, the result was a reduction in the global stock of nuclear warheads from about 65,000 in 1991 to about 10,000 today. The effect has worn off, however, and two separate but related nuclear arms races have begun: between the U.S. and Russia and the U.S. and China, plus proliferation crises with the “rogue” states, North Korea and Iran. The perverse dynamics underlying these crises will be explained and possible initiatives to mitigate them will be discussed, including a:


• U.S. no-first use policy,
• Restoration of limits on ineffective but provocative ballistic missile defenses,
• Resumption of US-Russian nuclear reductions along with a cap on China’s nuclear buildup,
and
• Strengthening the nonproliferation regime with bans on the separation of plutonium and on
national uranium enrichment capabilities.


Finally, the effectiveness of activist citizens teamed up with scientists for “credibility” working to educate Congress – as in the “Freeze” movement – will be recounted.
