While the charge radius of the proton is well known, its gluon radius and shape has never been measured. Furthermore, gluons exist in nature solely as vacuum fluctuations, and by measuring how they fluctuate inside heavy nuclei will put to the test our understanding of<br> quantum field theory and the vacuum. It turns out that a firm handle of initial state spatial distributions and fluctuations of gluons also play an important role in our understanding of heavy ions collisions at the LHC and RHIC, as well as for some aspects of the young universe shortly after Big Bang.</p><p style="margin: 0px;" data-mce-style="margin: 0px;"> </p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><strong><span style="font-size: 14.0pt; line-height: 107%; font-family: 'Times New Roman',serif;" data-mce-style="font-size: 14.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Friday, June 16, 2017</span></strong></p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><strong><span style="font-size: 14.0pt; line-height: 107%; font-family: 'Times New Roman',serif;" data-mce-style="font-size: 14.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">11:00 am</span></strong></p><p style="text-align: center; margin: 0px;" data-mce-style="text-align: center; margin: 0px;"><strong><span style="font-size: 14.0pt; line-height: 107%; font-family: 'Times New Roman',serif;" data-mce-style="font-size: 14.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">CEBAF F113</span></strong></p></div><div><br></div><div data-marker="__SIG_POST__">-- <br></div><div>Stephanie Tysor<br>Hall A Administrative Assistant<br>Thomas Jefferson National Accelerator Facility<br>(office)757-269-6005 (fax)757-269-5235</div></div></body></html>
