Observation of the Omega_b^- and Measurement of the Properties of the Xi_b^- and Omega_b^-

CDF Collaboration, T. Aaltonen

We report the observation of the bottom, doubly-strange baryon Omega^-_b through the decay chain Omega^-_b -> J/psi Omega^-, where J/psi -> mu^+ mu^-, Omega^- -> Lambda K^-, and La…

Search for the Neutral Current Top Quark Decay t-->Zc Using the Ratio of Z-Boson + 4 Jets to W-Boson + 4 Jets Production

CDF Collaboration, T. Aaltonen

We have used the Collider Detector at Fermilab (CDF II) to search for the flavor-changing neutral-current (FCNC) top quark decay ${t\goes Zc}$ using a technique employing ratios of…

Measurement of Cross Sections for Jet Production in Events with a Boson in Collisions at TeV

CDF collaboration, T. Aaltonen

A measurement of the $\bjet$ production cross section is presented for events containing a boson produced in collisions at TeV, using data correspond…

Search for new particles decaying into dijets in proton-antiproton collisions at sqrt(s) = 1.96 TeV

The CDF Collaboration, T. Aaltonen

We present a search for new particles whose decays produce two jets (dijets) using proton-antiproton collision data corresponding to an integrated luminosity of 1.13 fb-1 collected…

Top Quark Mass Measurement in the Lepton plus Jets Channel Using a Modified Matrix Element Method

CDF Collaboration, T. Aaltonen

We report a measurement of the top quark mass, m_t, obtained from ppbar collisions at sqrt(s) = 1.96 TeV at the Fermilab Tevatron using the CDF II detector. We analyze a sample cor…

Search for top-quark production via flavor-changing neutral currents in W+1 jet events at CDF

CDF Collaboration, T. Aaltonen

We report on the first search for top-quark production via flavor-changing neutral-current (FCNC) interactions in the non-standard-model process u(c)+g -> t using ppbar collision d…
