Looking for Single Top Quarks in Dø Data
نویسنده
چکیده
The search for the electroweak production of top quarks is entering an exciting time: with the ever increasing luminosity furnished by the Tevatron pp̄ Collider at Fermilab and sophisticated analysis techniques we are now able to approach the expected standard model production cross section for this new mode of production. Using 370 pb of DØ data and likelihoods as discriminants to extract the signal from the large backgrounds, we set upper limits on the standard model production cross section in the s-channel of 5.0 pb and in the t-channel of 4.4 pb, at 95% confidence level.

Search for Single-top-quark Production at the Tevatron
This article reports on recent searches for single-top-quark production by the CDF and DØ collaborations at the Tevatron. Neither two CDF analyses, using data corresponding to 695 pb of integrated luminosity, nor a DØ search based on 370 pb of data can establish a signal for this standard model process. These null results translate in upper limits on the cross section of 2.9 pb for the t-channe...

متن کاملDØ Note 5397-CONF An Improved Search for Single Top Quarks using Bayesian Neural Networks
We report the results of an improved Bayesian neural network (BNN) analysis of 0.9 fb−1 of DØ data. The observed excess of events over background has a p-value of 0.081%, assuming the background-only hypothesis, which corresponds to a significance of 3.1 standard deviations for a Gaussian density. The p-value computed using the Standard Model (SM) single top production cross section of 2.9 pb i...
متن کاملTop Mass Measurements with the DØ Detector
Top quarks at the tevatron are produced both singly and in pairs. However the single top production mode has both a smaller cross section, and more importantly a large irreducible background. When produced in pairs, both top and anti-top decay into aW boson and b quark, theW boson can then decay into a lepton and neutrino or a pair of quarks, and finally the b quarks, and any light quarks (u,d,...
متن کاملDØ Note 5392-CONF Improved Search for Single Top Quark Production Using The Matrix Element Analysis Technique in 0.9 fb of Data
We present an improved search for single top quarks using the matrix element analysis technique at D0 using 0.9 fb of Run II data. It builds on the work presented in Ref. [1]. From a comparison of the matrix element discriminants between data and the background model, assuming a Standard Model cross section ratio of σs/σt = 0.44, we measure the single top quark production cross section: σ (pp̄ →...
