[Theory-seminars] Cake Seminar Today - Adam Freese

[Caroline Silva Rocha Costa]

Dear all,

Today, at 1:00PM (EST), we are resuming our Cake Seminar series with a seminar given by Adam Freese of JLab in room F224-225.  Please see below for the title and abstract.

Title:
A separable Bethe-Salpeter approach to deuteron structure

Abstract:
Motivated by the desire to maintain manifest Lorentz covariance in calculations of deuteron structure, I model the nucleon-nucleon interaction using a non-local separable interaction Lagrangian. The Bethe-Salpeter equation for the deuteron's bound state vertex is separable and solvable in this model. With the deuteron vertex in hand, I calculate the electromagnetic and partonic structure of the deuteron, which both receive significant contributions from two-body currents. I also explore the deuteron wave function in the non-relativistic limit, finding that good physical behavior at the origin imposes several constraints on the model parameters.


Best regards,
Caroline, Joe & Zheng-Yang
