[Theory-seminars] Theory Seminar Monday - Frank Vera Vega

[Colin Egerer]

Hello All,

This coming Monday, March 20th, at 1:00 PM (EDT), Frank Vera Vega will give our next hybrid theory seminar. If you will be on-site and are comfortable doing so, please join us in room L102 of CEBAF Center. Otherwise, Frank's seminar will also be provided virtually on our usual ZoomGov link:

Please see below for the title and abstract.

Theory Seminar
Monday, March 20th at 1:00 PM

Frank Vera Vega (Florida International University)
will discuss "Observables for electro-scattering on targets with arbitrary spin"

Abstract:
Starting from the Weinberg formalism for the construction of fields for arbitrary spin, we propose an algorithm for the construction of the independent operators that enter the scattering amplitude associated with electromagnetic observables. This procedure is useful for the systematic study of the structure of hadrons and nuclei. In particular, it is very convenient in the case of spin-dependent observables. Since new features appear in the hadronic structure of higher spin targets, the investigation of their properties can improve our understanding of the strong force. As a proof of principle, we apply this method to the description of elastic electroscattering on a spin 1 target, such as the deuteron. The result of calculations within Instant and Light-Front forms of dynamics is presented, together with a systematic identification of the electromagnetic form factors and potential extensions of the formalism to hard exclusive processes on the deuteron.

Have a pleasant weekend!
Caroline, Colin, & Patrick
