[Theory-seminars] Theory Seminar Monday - Mischa Batelaan

[Colin Egerer]

Hello All,

This coming Monday, October 31st at 9:00 AM (EDT), Mischa Batelaan will give our next (virtual) theory seminar.
Mischa's seminar will be held virtually on our usual ZoomGov link: https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09
Please see below for the title and abstract.

Theory Seminar
Monday, October 31st at 9:00 AM

Mischa Batelaan (University of Adelaide)
will discuss a "Lattice QCD calculation of Hyperon transition form factors using the Feynman-Hellmann method"

Abstract:
Lattice QCD calculations of Hyperon transition form factors are relevant to setting constraints on the elements of the CKM matrix. I will present recent work from the QCDSF-UKQCD-CSSM collaboration on an extension to the Feynman-Hellmann method which allows for the calculation of these transition form factors. The Feynman-Hellmann approach only requires the calculation of lattice two-point functions which reduces the complexity of dealing with the excited state contaminations. The results of the form factors relevant to the semi-leptonic decay of the Sigma baryon will be discussed and compared to results from a calculation using the conventional three-point function approach.

Have a pleasant weekend!
Caroline, Colin & Patrick
