This book was released on 2011 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: We perform a search for long-lived neutral particles decaying into a photon and invisible particles in pp collisions at a center-of-mass energy of 7 TeV at the Large Hadron Collider. In the context of gauge mediated supersymmetry with the lightest neutralino as the next-to-lightest supersymmetric particle and the gravitino as the lightest supersymmetric particle, the neutralino can decay into a gravitino and a photon with a non-zero lifetime. The impact parameter of the photon relative to the beam-beam collision point can be reconstructed using converted photons. The method is sensitive to lifetimes of the order of [Special characters omitted.] (0.1 ns). The data sample corresponds to an integrated luminosity of 2.1 ± 0.1 fb -1 recorded in the first part of 2011 by the CMS experiment at the LHC at [Special characters omitted.] = 7 TeV. The search is performed using events containing photons, missing transverse energy and jets. Upper limits at the 95% confidence level are presented on the cross section for such particles from pair-production, each of which decays into a photon and invisible particles.

Available in PDF, EPUB and Kindle. Book excerpt: We report the results of a search for a narrow resonance in electron-positron events in the invariant mass range of 150-950 GeV/c2 using 1.3 fb−1 of p{bar p} collision data at √s=1.96 TeV collected by the CDF II detector at Fermilab. No significant evidence of such a resonance is observed and we interpret the results to exclude the standard model-like Z′ with a mass below 923 GeV/c2 and the Randall-Sundrum graviton with a mass below 807 GeV/c2 for k/{bar M}{sub pl} = 0.1, both at the 95% confidence level. Combining with di-photon data excludes the Randall-Sundrum graviton for masses below 889 GeV/c2 for k/{bar M}{sub pl} = 0.1.

This book was released on 2011 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: A model-independent signature-based search for physics beyond the Standard Model is performed in the photon~+ jets~+ missing transverse energy channel in \ppbar collisions at a center of mass energy of 1.96 TeV using the CDF II detector. Events with a photon + jets are predicted by the Standard Model and also by many theoretical models beyond the Standard Model. In the Standard Model, the main mechanisms for photon~+ jets production include quark-antiquark annihilation and quark-gluon scattering. No intrinsic missing transverse energy is present in any of these Standard Model processes. In this search, photon~+ $\geq$1 jet and photon~+ $\geq$2 jet events are analyzed with and without a minimum requirement on the missing transverse energy. Numerous mass distributions and kinematic distributions are studied and no significant excess over the background prediction is found. All results indicate good agreement with expectations of the Standard Model.
