Abstract
|
|
|
|
| We search for Z′ bosons in dielectron events produced in pp̅ collisions at √s=1.96 TeV, using 0.45 fb-1 of data accumulated with the Collider Detector at Fermilab II detector at the Fermilab Tevatron. To identify the Z′→e+e- signal, both the dielectron invariant mass distribution and the angular distribution of the electron pair are used. No evidence of a signal is found, and 95% confidence level lower limits are set on the Z′ mass for several models. Limits are also placed on the mass and gauge coupling of a generic Z′, as well as on the contact-interaction mass scales for different helicity structure scenarios. |
