The Search for Physics Beyond the Standard Model in the $B \bar{B}$ Spectrum Observed in Tevatron $p\bar{p}$ Collisions
Many extensions have been proposed to the Standard Model of fundamental particles and interactions, therefore we have conducted a general search with the Collider Detector at Fermilab (CDF) for particles which would be expected to appear as a resonance in the b$\bar{b}$ mass spectrum produced in proton-antiproton collisions at a center-of-mass energy of √s = 1.8 TeV at the Fermilab Tevatron collider.
Searches for Physics Beyond the Standard Model in Ttbar Events
The top quark is currently only observed at the Tevatron, where it is mainly produced in t{bar t} pairs. Due to the very high mass of the top quark compared to the other quarks and the gauge bosons, it is expected to play a special role in electroweak symmetry breaking. Therefore it might be especially sensitive to new physics. Measurements of various production and decay quantities of the top quark could lead to discoveries of physics beyond the standard model. Several such measurements were performed by the CDF collaboration during Run1 of the Tevatron. These measurements and first results from CDF in Run2 are presented.
Beyond the Standard Model at Tevatron
This article presents recent results of searches for physics beyond the Standard Model using the CDF and the D0 detector at the Fermilab Tevatron Collider. All results shown correspond to analysis performed using the past 1992--1996 Fermilab Tevatron run 1 data (roughly 100 pb−1 per each experiment). In particular, the authors describe recent Tevatron searches for scalar top in the b + l + missing-E{sub T} channel, for squark and gluinos using like-sign dileptons (LS), for large extra space-time dimensions and the search for leptoquarks and technicolor in the missing-E{sub T}+heavy flavor jet events. Tight limits on the existence of such models have been set.
