Search for anomalous Wtb couplings in single top quark production.
In 0.9 fb(-1) of pp[over] collisions, the D0 Collaboration presented evidence for single top quark production in events with an isolated lepton, missing transverse momentum, and two to four jets. We examine these data to study the Lorentz structure of the Wtb coupling. The standard model predicts a left-handed vector coupling at the Wtb vertex. The most general lowest dimension, CP-conserving L...
متن کاملComplete Calculations of Wbb̄ and Wbb̄ + jet Production at Tevatron and LHC: Probing Anomalous Wtb Couplings in Single Top Production
We present the results of a complete tree level calculation of the processes pp(p̄) → Wbb̄ and Wbb̄ + jet that includes the single top signal and all irreducible backgrounds simultaneously. In order to probe the structure of the Wtb coupling with the highest possible accuracy and to look for possible deviations from standard model predictions, we identify sensitive observables and propose an optim...
متن کاملATLAS sensitivity to Wtb anomalous couplings in top quark decays
We study the sensitivity of the ATLAS experiment to Wtb anomalous couplings in top pair production with semileptonic decay, pp→ tt̄→WbWb̄ with one of the W bosons decaying leptonically and the other hadronically. Several observables are examined, including the W helicity fractions and new quantities recently introduced, such as the ratios of helicity fractions and some angular asymmetries defined...
متن کاملPolarized single top quark production in eγ collision and anomalous Wtb couplings
We investigate the potential of eγ collisions to probe anomalous Wtb couplings via the polarized single top quark production process eγ → tb̄ν̄e. We find 95% confidence level limits on the anomalous coupling parameters F2L and F2R with an integrated luminosity of 500 fb −1 and √ s=0.5, 1 and 1.5 TeV energies. The effects of top quark spin polarization on the anomalous Wtb couplings are discussed....
متن کاملProbing Anomalous Wtb Coupling via Single Top Production at TeV Energy γe Colliders
Results of complete tree level calculations of the single top production reaction γe −→ νt̄b at the Next Linear Collider, including the contribution of anomalous operators to the Wtb coupling are presented. The sensitivity for probing the structure of the Wtb coupling in a model independent way is analyzed and found to be significantly higher than for comparable measurements at the Tevatron. The...
