Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a search for squarks in supersymmetric models which allow R-parity violation. Electron-proton and positron-proton collisions taken at a centre of mass energy of 320 GeV have been investigated using the H1 detector at HERA. No deviation from the Standard Model has been found and exclusion limits in various supersymmetric models have been derived.

Book Lepton and Photon Interactions at High Energies

Download or read book Lepton and Photon Interactions at High Energies written by Richard Brenner and published by World Scientific. This book was released on 2006 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lepton-Photon symposiums ? as represented by the contributions in this volume ? are among the most popular conferences in high energy physics since they give an in-depth snapshots of the status of the field as provided by leading experts.The volume covers the latest results on flavor factories, quantum chromodynamics (QCD), electroweak physics, dark matter searches, neutrino physics and cosmology, from a phenomenological point of view. It also offers a glimpse of the immediate future of the field through summaries on the status of the next generation of high energy accelerators and planned facilities for astroparticle physics.The review nature of the articles makes the volume particularly useful to students, as well as being of interest to established researches in high-energy physics and related fields.

Book Searches for R parity violating Supersymmetry in Pp Collisions at Sqrt s

Download or read book Searches for R parity violating Supersymmetry in Pp Collisions at Sqrt s written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented from searches for R-parity-violating supersymmetry in events produced in pp collisions at sqrt(s)=8 TeV at the LHC. Final states with 0, 1, 2, or multiple leptons are considered independently. The analysis is performed on data collected by the CMS experiment corresponding to an integrated luminosity of 19.5 inverse femtobarns. No excesses of events above the standard model expectations are observed, and 95% confidence level limits are set on supersymmetric particle masses and production cross sections. The results are interpreted in models featuring R-parity-violating decays of the lightest supersymmetric particle, which in the studied scenarios can be either the gluino, a bottom squark, or a neutralino. In a gluino pair production model with baryon number violation, gluinos with a mass less than 0.98 and 1.03 TeV are excluded, by analyses in a fully hadronic and one-lepton final state, respectively. An analysis in a dilepton final state is used to exclude bottom squarks with masses less than 307 GeV in a model considering bottom squark pair production. Multilepton final states are considered in the context of either strong or electroweak production of superpartners, and are used to set limits on the masses of the lightest supersymmetric particles. These limits range from 300 to 900 GeV in models with leptonic and up to approximately 700 GeV in models with semileptonic R-parity-violating couplings.

Book Search for R parity Violating Supersymmetry with Displaced Vertices in Proton proton Collisions at Sqrt s

Download or read book Search for R parity Violating Supersymmetry with Displaced Vertices in Proton proton Collisions at Sqrt s written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are reported from a search for R-parity violating supersymmetry in proton-proton collision events collected by the CMS experiment at a center-of-mass energy of sqrt(s)=8 TeV. The data sample corresponds to an integrated luminosity of 17.6 inverse femtobarns. This search assumes a minimal flavor violating model in which the lightest supersymmetric particle is a long-lived neutralino or gluino, leading to a signal with jets emanating from displaced vertices. In a sample of events with two displaced vertices, no excess yield above the expectation from standard model processes is observed, and limits are placed on the pair production cross section as a function of mass and lifetime of the neutralino or gluino. At 95% confidence level, the analysis excludes cross sections above approximately 1 fb for neutralinos or gluinos with mass between 400 and 1500 GeV and mean proper decay length between 1 and 30 mm. Assuming gluino pair production cross sections, gluino masses are excluded below 1 and 1.3 TeV for mean proper decay lengths of 300 micrometers and 1 mm, respectively, and below 1.4 TeV for the range 2-30 mm. The results are also applicable to other models in which long-lived particles decay into multijet final states.

Book Search for R parity Violating Supersymmetry Via the LL Anti E Couplings Lambda 121 Lambda 122 Or Lambda 133 in P Anti p Collisions at S

Download or read book Search for R parity Violating Supersymmetry Via the LL Anti E Couplings Lambda 121 Lambda 122 Or Lambda 133 in P Anti p Collisions at S written by and published by . This book was released on 2006 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A search for gaugino pair production with a trilepton signature in the framework of R-parity violating supersymmetry via the couplings ?121, ?122, or ?133 is presented. The data, corresponding to an integrated luminosity of L ≈ 360 pb−1, were collected from April 2002 to August 2004 with the D0 detector at the Fermilab Tevatron Collider, at a center-of-mass energy of √s = 1.96 TeV. This analysis considers final states with three charged leptons with the flavor combinations eel, ??l, and ee? (l = e or ?). No evidence for supersymmetry is found and limits at the 95% confidence level are set on the gaugino pair production cross section and lower bounds on the masses of the lightest neutralino and chargino are derived in two supersymmetric models.
