<p class="MsoNormal">A Special Colloquium by Matthew Reece (Harvard) titled “Theory Confronts the LHC: Sizing Up Supersymmetry” will be held tomorrow (WED) at 3:30 PM in the Smith Seminar Room. A reception precedes the colloquium at 3:00 pm in the Atrium.
Please come and hear from one of our HET faculty candidates.<o:p></o:p></p>
<p>Abstract: <span lang="EN" style="font-size:10.0pt;font-family:"Arial","sans-serif"">
The Large <span class="scayt-misspell">Hadron</span> <span class="scayt-misspell">
Collider</span> has been operating for more than a year and delivering exciting results that have already changed the landscape of particle physics. One central question that we expect the
<span class="scayt-misspell">LHC</span> to answer is the nature of the "hierarchy problem," or the question of why the electromagnetic and weak nuclear forces are much stronger than gravity. I will explain why this is a puzzle and why it is of central importance
for fundamental physics. <span class="scayt-misspell">Supersymmetry</span> has long been the fondest hope of theorists for a new mechanism that can explain the hierarchy, but the
<span class="scayt-misspell">LHC</span> has already ruled out some of the most striking possible manifestations of
<span class="scayt-misspell">supersymmetry</span>. A dramatic recent hint of the Higgs boson at a mass of about 125
<span class="scayt-misspell">GeV</span>, if it holds up, will have profound implications for whether and how
<span class="scayt-misspell">supersymmetry</span> is realized in nature. Unraveling these puzzles will require more data, but I will give a snapshot of the
<span class="scayt-misspell">LHC's</span> theory implications, and a glimpse of where the data might lead us in the coming months.<o:p></o:p></span></p>
