Show moreThis Proceedings of the XLIII International Symposium on Multiparticle Dynamics (ISMD 2013) contains summaries of some of the outstanding research presented at the 2013 meeting. The 2013 Symposium was held at the Illinois Institute of Technology (IIT) in Chicago, Illinois over September 15–20. The Symposium was jointly organized by the IIT College of Science and the High Energy Physics Division of Argonne National Laboratory. More than 100 participants from nearly 20 countries participated in the Symposium to review progress and discuss upcoming issues in the fields of high-energy physics, nuclear physics and astrophysics. The International Symposium on Multiparticle Dynamics (ISMD) is a major international high-energy conference which attracts participants with a common interest in reactions involving a large number of particles. From the beginning, the goal was to bring experimentalists and theorists together to discuss all aspects multiparticle dynamics, from new analysis techniques to the latest discoveries.

Show moreOne of the strengths of the LHC is its capacity for the discovery of new physics. As a consequence of many BSM theories, W′ bosons make an ideal particle to search for to constrain many models. One mode in particular has relatively low background: Single top quark production mediated by a W′ boson. For W′ masses less than 1500 GeV, all the decay products of the top quark are visible, and the strongest channel is the top’s decay into an electron or muon, with the associated neutrino and a bottom jet. As the W′ mass increases, the decay products from the highly boosted top and bottom quarks from the W′ appear as fat jets; boosted top tagging algorithms abound, and we propose a boosted bottom tag to set an exclusion limit of 2750 GeV for standard model-like couplings with existing 8 TeV data.
