演題(Title)：SOME ASPECTS OF STRANGENESS IN FEW-BODY PHYSICS
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?
