講師： Benjamin F. Gibson (Los Alamos National Laboratory)
演題：Some Aspects of strangeness in few-body physics
場所：ウェスト1号館7階 物理セミナー室3 (W1-A-723室)

概要：
We nuclear theorists build computer models of nuclei and of nuclear reactions.
We take the models seriously: that is, we calculate measured physical observables and attempt to understand the underlying physics.
I will report some of our successes in few-nucleon (neutron and proton or baryons without strangeness) physics – primarily the tri-nucleons and the alpha particle.
I will describe the successful utilization of this understanding to predict the binding energies of the heavier p-shell nuclei.
Then I will address the question of whether our models of nuclei in the strangeness zero sector extrapolate to explain nuclei in the strangeness -1 sector in which the Lambda baryon plays a key role.
Or are our models merely an exquisite tool for interpolation in the non-strange nuclear physics realm?
