Download or read book Search for Heavy Long-lived Charged R-hadrons with the ATLAS Detector in 3.2 Fb-1 of Proton-proton Collision Data at [mml written by . This book was released on 2016. Available in PDF, EPUB and Kindle. Book excerpt: A search for heavy long-lived charged R -hadrons is reported using a data sample corresponding to 3.2 fb -1 of proton-proton collisions at s=13 TeV collected by the ATLAS experiment at the Large Hadron Collider at CERN. The search is based on observables related to large ionisation losses and slow propagation velocities, which are signatures of heavy charged particles travelling significantly slower than the speed of light. No significant deviations from the expected background are observed. Lastly, upper limits at 95% confidence level are provided on the production cross section of long-lived R -hadrons in the mass range from 600 GeV to 2000 GeV and gluino, bottom and top squark masses are excluded up to 1580 GeV, 805 GeV and 890 GeV, respectively.

Book Synopsis Search for Excited Randall-Sundrum Gravitons with Semi-Leptonic Diboson Final States in 4.7 Fb-1 of Proton-Proton Collisions Using the ATLAS Detector at the Large Hadron Collider by : Eric Lloyd Williams

Download or read book Search for Excited Randall-Sundrum Gravitons with Semi-Leptonic Diboson Final States in 4.7 Fb-1 of Proton-Proton Collisions Using the ATLAS Detector at the Large Hadron Collider written by Eric Lloyd Williams. This book was released on 2012. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes a search for resonant WW and WZ production in the lvjj decay channel using 4.701 fb-1 of sqrt(s) = 7 TeV LHC collision data collected by the ATLAS detector. Events with a single charged lepton, at least two jets and missing transverse energy are analyzed and no significant deviation from the Standard Model prediction is observed. Upper limits on the production cross section are interpreted as lower limits on the mass of a resonance and are derived assuming two warped extra-dimension production modes: the original Randall-Sundrum (RS1) model and the more recent "bulk" Randal-Sundrum (Bulk RS) model. The mass range for both models is excluded at 95% CL with a lower mass limit for an RS1 graviton of 936 GeV and 714 GeV for the Bulk RS graviton.

Book excerpt: The pseudorapidity distribution of charged hadrons in pp collisions at [arrow]"=13 TeV is measured using a data sample obtained with the CMS detector, operated at zero magnetic field, at the CERN LHC. Furthermore, this yield of primary charged long-lived hadrons produced in inelastic pp collisions is determined in the central region of the CMS pixel detector).

Download or read book Search for Disappearing Tracks in Proton-proton Collisions at [arrow]" written by . This book was released on 2015. Available in PDF, EPUB and Kindle. Book excerpt: A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. Disappearing tracks are identified as those with little or no associated calorimeter energy deposits and with missing hits in the outer layers of the tracker. The search uses proton-proton collision data recorded at [arrow]" = 8 TeV that corresponds to an integrated luminosity of 19.5 fb-1. The results of the search are interpreted in the context of the anomaly-mediated supersymmetry breaking (AMSB) model. The number of observed events is in agreement with the background expectation, and limits are set on the cross section of direct electroweak chargino production in terms of the chargino mass and mean proper lifetime. At 95% confidence level, AMSB models with a chargino mass less than 260 GeV, corresponding to a mean proper lifetime of 0.2 ns, are excluded.
