The Physics & Astronomy Colloquium Series presents Silas Beane of the University of Washington on “Aspects of 21st Century Nuclear Physics” on Friday, Jan. 30, at 4:10 p.m. in Walter 245.

Abstract: Over the last several decades, theoretical nuclear physics has been evolving from a very successful phenomenology of the properties of nuclei, to a first-­‐principles derivation of the properties of the visible matter in the Universe from the known underlying theories of Quantum Chromodynamics (QCD) and Quantum Electrodynamics (QED). These developments are being achieved using lattice QCD, a method for treating QCD numerically with large computers, together with advances in nuclear many-­body methods. After a brief motivational introduction, I will present some of the recent calculations of the properties of the simplest nuclear and hypernuclear systems using lattice QCD. These calculations include the first physical predictions of baryon‐baryon scattering, the spectrum of the light nuclei and hypernuclei, and most recently, nuclear magnetic moments. I will also discuss how recent work is beginning to illuminate the nuclear fine‐tunings that in some sense define the Universe that we live in.
