DC.00001: A search for new physics with Razor kinematic variables in proton-proton collisions at $\sqrt{s}$=8 TeV with the ATLAS detector at the LHC Invited Speaker: Anton Kravchenko The experimental signature for our search is jets and missing energy. The Razor variables are built using two mega-jets and are designed to discriminate against QCD multi-jets background. The dominant background events for this analysis are Z+jets, W+jets, $t\bar{t}$ and QCD, for each of which a dedicated control region is defined. In each control region the MC is normalized to the data. This normalization factor is applied to MC and an extrapolation is made from the control region into the signal region to estimate the background events in the data signal region. In the absence of a statistically significant excess, limits are set on the parameters of the simplified models involving the strong production of squark and gluino pairs.\\[4pt] In collaboration with Zach Marshall, Lawrence Berkeley National Laboratory; Milind Purohit, University of South Carolina; and Daniel Bullock, Amir Farbin, Louise Heelan, University of Texas at Arlington.

DC.00002: Higgs Boson Studies at CMS Invited Speaker: Robert Hirosky This talk presents an overview of recent highlights from the Run 1 Higgs boson studies at the CMS experiment. Measurements of production cross sections and properties of the observed boson at CMS are compared with standard model expectations. Selected topics covering searches for beyond the standard model Higgs boson(s) and prospects for future studies are also summarized. [Preview Abstract] |

DC.00003: Overview talk of ALICE results Invited Speaker: Natasha Sharma A strongly coupled Quark-Gluon Plasma is formed at very high temperature and energy densities in ultra-relativistic heavy ion collisions. The formed medium/source expand and cools down with time and produce particles. The ALICE experiment at the LHC has performed several measurements using the capabilities of its various sub-systems to explore and understand the properties of the medium formed. In this talk, we will present recent results obtained by the ALICE experiment for pp, p-Pb and Pb-Pb collisions at the LHC energies. These include results on charged particle multiplicity, identified particle production and nuclear modification factor. Their dependencies on colliding system and on multiplicity of produced particles will also be discussed. [Preview Abstract] |
