Abstract:

This report describes the first search for top squark pair production in the channel (Formula presented)+jets+(Formula presented) using (Formula presented) pb(Formula presented) of data collected using the D脴 detector. A 95% confidence level upper limit on (Formula presented) is presented. The limit is above the theoretical expectation for (Formula presented) for this process, but does show the sensitivity of the current D脴 data set to a particular topology for new physics. 漏 1998 The American Physical Society.

Abstract:

Using data collected by the CLEO II detector at a center-of-mass energy on or near the (Formula presented) resonance, we have determined the 90% confidence level upper limit (Formula presented) for electrons with momentum above (Formula presented) We have also obtained the limit (Formula presented) at the 90% confidence level and measured the ratio (Formula presented). 漏 1998 The American Physical Society.

Abstract:

We present a study of (Formula presented) production in (Formula presented) collisions at (Formula presented) from 97 (Formula presented) of data collected in the (Formula presented) (渭渭纬) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent with the standard model predictions. We obtain limits on anomalous (Formula presented) and (Formula presented) couplings for form factor scales (Formula presented) and (Formula presented) Combining this analysis with our previous results yields 95% C.L. limits (Formula presented) (Formula presented) (Formula presented) and (Formula presented) for a form factor scale (Formula presented). 漏 1998 The American Physical Society.
