<div><br>
</div>
<div><span style="font-family: Calibri, Helvetica, sans-serif;">Today at 1:00 PM (EDT), Chien-Yeah Seng will give our next hybrid theory seminar. We want to highlight that this seminar is one of the ODU + JLab joint position interviews. If you will be on-site
and are comfortable doing so, please join us in room L102 of CEBAF Center. Otherwise, Chien-Yeah's seminar will also be provided virtually on our usual ZoomGov link:

<div><span style="font-family: Calibri, Helvetica, sans-serif;"><b><u>Chien-Yeah Seng</u></b> (Michigan State and University of Washington)</span></div>
<div><span style="font-family: Calibri, Helvetica, sans-serif;">will discuss "Nuclear physics in Vud"</span></div>

<div><span style="font-family: Calibri, Helvetica, sans-serif;"><u><b>Abstract</b></u>:</span></div>
<div><span style="font-family: Calibri, Helvetica, sans-serif;">The experimental determination of the first-row Cabibbo-Kobayashi-Maskawa (CKM) matrix element Vud has reached an impressive 0.03% level, serving as one of the most powerful tests of the Standard
Model (SM) at low energies. In recent years, an apparent deficit of the first-row CKM matrix unitarity at the level of 3 sigma is observed, which provides possible indications of New Physics. The major obstacles to a confirmed discovery are the hadronic and
nuclear theory uncertainties in the SM inputs that enter the Vud extraction. In this seminar I will describe how a combination of experimental data, lattice QCD and ab-initio nuclear theory calculations could ultimately pin down these inputs, and how we may
benefit from current and future experimental programs at Jefferson Lab.</span></div>
