This book was released on 2016. Available in PDF, EPUB and Kindle. Book excerpt: A dedicated search is presented for new phenomena in inclusive eight- and ten-jet final states with low missing transverse momentum, with and without identification of jets originating from b quarks. The analysis is based on data from proton-proton collisions corresponding to an integrated luminosity of 19.6 inverse femtobarns collected with the CMS detector at the LHC at sqrt(s) = 8 TeV. The dominant multijet background expectations are obtained from low jet multiplicity control samples. Data agree well with the standard model background predictions, and limits are set in several benchmark models. Colorons (axigluons) with masses between 0.6 and 0.75 (up to 1.15) TeV are excluded at 95% confidence level. Similar exclusion limits for gluinos in R-parity violating supersymmetric scenarios are from 0.6 up to 1.1TeV. These results comprise the first experimental probe of the coloron and axigluon models in multijet final states.

Available in PDF, EPUB and Kindle. Book excerpt: A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at $\sqrt{s}$ = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb−1collected with the CMS detector at the LHC. The data sample is divided into three jet multiplicity categories (3-5, 6-7, and ≥8 jets), and studied further in bins of two variables: the scalar sum of jet transverse momenta and the missing transverse momentum. The observed numbers of events in various categories are consistent with backgrounds expected from standard model processes. Exclusion limits are presented for several simplified supersymmetric models of squark or gluino pair production.

Book Synopsis Search for New Physics in Proton-proton Collisions at 7 TeV in Events with a Single Lepton, Jets, and Missing Transverse Momentum by : Finn O'Neill Rebassoo

Download or read book Search for New Physics in Proton-proton Collisions at 7 TeV in Events with a Single Lepton, Jets, and Missing Transverse Momentum written by Finn O'Neill Rebassoo. This book was released on 2011. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents results for a search for new physics based on 36 pb-1 of data taken during 2010 by the CMS experiment at the Large Hadron Collider (LHC). We specifically look at the signature with a single isolated lepton, jets, and large missing transverse momentum. To predict the standard model backgrounds in this search, two separate and complementary methods are employed, each of which use control samples in the data. The standard model background predictions are consistent with the observed number of events in both the muon and electron channels and for both background prediction methods. In addition, the observed missing transverse momentum distribution agrees well with the standard model prediction. In the absence of a signal we proceed to set limits in the contrained minimal supersymmetric extension of the standard model (CMSSM) parameter space.
