      Inclusive W/Z Cross Section Measurement at CMS

      Andrew Michael Kubik, Northwestern University
      Abstract:
      We present the CMS measurement of the W and Z inclusive production cross
      sections in proton-proton collisions with sqrt(s) = 7 TeV at the LHC.
      Results are obtained using both the electron and muon channels and
      approximately 2.9 pb^-1 of integrated luminosity. Descriptions of event
      selection, efficiency measurements, and background estimations are given.

      Measurement of W->munu and Z->mumu cross-sections with ATLAS
      Abstract:
      I will present the first inclusive cross-section measurements of the W->munu and Z->mumu processes by the ATLAS experiment. The
      results are based on approximately 300 nb-1 of data and contain 1181 W and 109 Z candidates. I will discuss the extraction of various
      efficiencies and correction factors and the methods used for background estimation. The measured values of the cross-sections are
      consistent with Standard Model predictions.

      Abstract:
      We are performing R&D for pixels for the LHCb Vertex Locator Upgrade. Initial investigations have focused on a derivative of the Medipix/Timepix family of chips for the front-end electronics. During the summer of 2009, a test beam run was done to demonstrate the suitability of Timepix, when bump bonded to a silicon pixel sensor. I will present preliminary analysis results including cluster characteristics, charge measurement (Landau distribution), resolution performance, bias voltage dependence, and reconstructed pulse shape. A tracking resolution of about 5 microns has been achieved for angled tracks indicating a very satisfactory resolution performance.

      First Results from ALICE C. Nattrass (Tennessee) (Wilson Hall One West)

      C. Nattrass (Tennessee)

      Wilson Hall One West

      Abstract: The ALICE detector is a general purpose detector optimized for measuring the properties of strongly interacting matter created in high energy heavy ion collisions at the LHC. The characteristic features of the ALICE detector are its low momentum cut off (100 MeV/c), its low material budget, and its excellent particle identification and vertexing capabilities. These features make ALICE well-suited for measurements over a wide kinematic range in proton-proton collisions, which serve both as a baseline for measurements in heavy ion collisions and as interesting measurements in their own right. The first results from ALICE's proton-proton program will be presented, including charged particle multiplicities, identified particle spectra, and anti-proton/proton ratios. These measurements are compared to Monte Carlo generators. Prospects for the upcoming heavy ion run will be discussed.

      Abstract: With just a small fraction of the expected 1/fb of integrated luminosity from LHC's first run delivered, the ATLAS experiment is already
      harvesting physics that surpasses the reach of previous experiments. I will overview select recent ATLAS results and discuss the potential
      of 1/fb of 7 TeV proton-proton data.

      Batavia, IL, USA

      Abstract:
      One year ago, the early LHC physics program was expected to include (a) commissioning and a rapid rise in luminosity, (b) rediscovery of the Standard Model, (c) Higgs, SUSY, and exotics searches with the most sensitivity at high-q^2, and (d) the unexpected. I will present results from CMS demonstrating how each of these expectations have been met or exceeded.

        Search for First Generation Leptoquarks in ATLAS 20m
        Abstract: Leptoquarks are hypothetical particles that carry both lepton and baryon number and are proposed to exist in a number of extensions to the standard model. This work presents a search for first generation Leptoquarks at the ATLAS detector. The search is for pair production of leptoquarks in which one would decay into a lepton/quark pair, and the other into a neutrino/quark pair yielding one high energy lepton, missing transverse energy and two high energy jets. The background, which is estimated by comparing Standard Model Monte Carlo with data, comes primarily from W production with jets and top production.

        Search for First-Generation Leptoquarks in CMS 20m
        Abstract We present the results of a search for pair production of first-generation scalar leptoquarks (LQ) in the final state arising from LQLQ -> eqeq using 1.1 pb^{-1} of pp collisions at sqrt{s} = 7 TeV collected with the CMS detector at the CERN LHC. The number of observed events is in good agreement with the predictions for standard model background processes, and we consequently set an upper limit on the LQ cross section times beta^2 as a function of the LQ mass, where beta is the branching fraction of LQ -> eq. We set a 95% C.L. lower limit on the mass of a first-generation scalar LQ at 220 GeV/c^2 for beta = 1.

        Extra Dimensions Searches in the Diphoton Final State at CMS 20m
        Abstract We present the commissioning of photon reconstruction and identification using 7 TeV collision data at CMS. The photon observables are measured and compared to Monte Carlo simulation. Two analyses searching for extra dimensions in the diphoton final state, large extra dimensions and wrapped extra dimensions searches, are also discussed.

        From W/Z to Higgs: ATLAS Higgs Sensitivity Prospects for 2010/2011 20m
        Abstract: In this talk we show the projections for the Higgs boson search with the ATLAS detector at the LHC, assuming an integrated luminosity of 1 fb-1 which is expected to be reached by the end of 2011. Particular emphasis is given to ongoing studies of the Standard Model W and Z boson production, in view of understanding some of the most important background processes in search for the Higgs boson.

        Supersymmetry Searches in ATLAS 20m
        Abstract: We describe the potential for discovering Supersymmetry (SUSY) using the ATLAS detector in the multi-jet and multi-lepton channels with associated missing transverse energy. A study of ATLAS sensitivity based on LHC data for typical signatures of R-Parity conserved SUSY models is presented. The possibilities of using kinematic variables in place of reconstructed missing transverse energy for such searches is investigated. These new variables are useful for reducing standard model backgrounds, especially for the zero lepton case. We describe a new method for estimating the contribution towards irreducible background for SUSY events arising from Z boson production with associated jets.
