Signals of supersymmetry in top quark decays at positron-electron and hadron-hadron colliders
… influence of supersymmetry on the search for the top quark (as yet, undiscovered) by studying the two specific processes: $e\sp+ e\sp-$ $\to$ $\Theta$ $\to$ $g\tilde{g}\tilde{k}$, where $\tilde{k}$ is either a $\tilde{g}$ or $\tilde{\gamma}$, and $pp \to$ $t\bar{t}X$ followed by $t$ $\to$ …

Search for flavor changing neutral currents in top quark decays using a two-leptons+track selection
A search for flavor-changing neutral currents in top quark decays is described. Data collected at a center- of-mass energy of √s = 7 TeV during 2011 corresponding to an integrated luminosity of 2.1 fb^{-1} are used. A cut-based analysis is used on top quark pair production events, where one top …

Measurement of W Boson Polarization in Top Quark Decay
… of the polarization of the W boson from top quark decay is an excellent test of the V-A form of the charged-current weak interaction in the standard model. Since the longitudinal W boson is intimately related to the electroweak symmetry breaking mechanism, and the standard model gives a …

MISSING TRANSVERSE ENERGY MEASUREMENT IN ATLAS DETECTOR:FIRST LHC DATA RESULTS AND IMPORTANCE FOR PHYSICS STUDY
… nels, as W, Z bosons decaying to τ leptons or top quark decays, and for miss are expected to be the key discovering channels. Events with large ET signature for new physics such as supersymmetry and extra dimensions. A miss measurement in terms of linearity and resolution is crucial for good ET …
