<p>Hi all, <br>
<br>
We will have our first PASS talk of the year next Monday.
Please join us at noon (from 12:00 pm to 1:00 pm) in
the Nebula Room (PHYS 3027).<br>

is particularly sensitive to the distribution of
high-momentum quarks, often referred to as 'superfast
quarks.' These quarks, which carry momentum exceeding that
of a nucleon, are linked to the short-distance structure of
nuclei. This region presents a promising opportunity to
investigate the role of quark degrees of freedom in nuclear
structure. The 12 GeV data from Jefferson Lab enables a more
precise study compared to the 6 GeV data, the maximum energy
achievable before the upgrade, as the higher <span
