[Theory-seminars] Cake Seminar TOMORROW - Jose Goity

[Colin Egerer]

Hello All,

Tomorrow, we will have a remote cake seminar given by Jose Goity of Hampton University and JLab at 1pm on the following zoom link: https://jlab-org.zoomgov.com/j/1613427345

In light of the recent COVID-19 Community Level increase from medium to high, we will not be holding the seminar in a specific room for folks that are physically at the lab. However, we will have a cake that will be available for pickup downstairs in the CEBAF lobby. You may socialize with masks on, but you must take the cake upstairs to your office to eat. We will have coffee available also in the theory wing.

Please see below for the details.

Cake Seminar
Wednesday, January 18th at 1:00 PM

Jose Goity (Hampton University/JLab)
will discuss " Normal single spin asymmetries: the 1/Nc expansion approach"

Abstract:
Normal spin asymmetries are an important tool in the study of hadron structure. They can be studied in a wide range of reactions in electron scattering, namely elastic, inclusive, semi-inclusive, and a wide range of energies. Experimental results are still few and far apart. Theoretical means of study are still limited, with the low energy purely elastic case being the only under almost complete control. In this talk we cover the next stage beyond that case, where the Delta resonance can be excited, and up to energies close to the next higher resonance. This regime is amenable to an approach that uses the 1/Nc expansion to unify the description of the EM interaction for nucleons and Delta, and where effects can be organized in powers of 1/Nc. The target single spin asymmetry is then studied to the next subleading order in 1/Nc. It is expected that the results are predictions accurate to that order.

Best,
Caroline, Colin, & Patrick
