Hi all,<br>
<br>
I was going over my APS talk and just want to make sure that I am not<br>
saying anything incorrect when going over my cartoon on slide 4.<br>
<br>
<a href="http://www.jlab.org/~posik/aps_2010.pdf">http://www.jlab.org/~posik/aps_2010.pdf</a><br>
<br>
I was going to say something along the lines:<br>
<br>
"The photon crashes into a quark and knocks it out of the neutron. The<br>
gluon then pulls the quark back in. It is this gluon "tension" that is<br>
d2."<br>
<br>
Please let me know if this is not correct.<br><br></blockquote><div><br></div><div>I think it would be better to say that the virtual photon imparts energy to the quark, and it <i>tries </i>to escape (the neutron), but the unaffected gluons and quarks in the neutron pull it back in. </div>
</div><div><br></div>if you say it gets out of the neutron, that means we have a free quark running around... outside the neutron...<br clear="all"><br>-- <br>-----------------------------------------------------------<br>
