The CDF Run II silicon detector is the largest operating detector of its kind in High Energy Physics, collecting p-pbar collision data at the Fermilab Tevatron since 2001. It provides precision tracking and vertexing which played a critical…
The 1992-1995 running of the Fermilab Tevatron ended with many important physics goals accomplished, including the discovery of the top quark, and the anticipation of many further questions to be answered in the future. After many upgrades…
After a five year upgrade period, the CDF detector located at the Fermilab Tevatron Collider is back in operation taking high quality data with all subsystems functional. We report on the status of the CDF experiment in Run II and discuss…
The Collider Detector at Fermilab (CDF) records proton-antiproton collisions at center of mass energy of 2.0 TeV at the Tevatron collider. A new collider run, Run II, of the Tevatron started in April 2001. Increased luminosity will result…
Run II at the Tevatron Collider started at the beginning of March 2001. With extensive upgrades on both detectors and electronics the CDF II began to collect data. This paper reviews early Run II physics results obtained by analyzing data…
A next generation silicon vertex detector is planned at CDF for the 1998 Tevatron collider run with the Main Injector. The SVX~II silicon vertex detector will allow high luminosity data-taking, enable online triggering of secondary vertex…
The physics program at the Fermilab Tevatron Collider will continue to explore the high energy frontier of particle physics until the commissioning of the LHC at CERN. The luminosity increase provided by the Main Injector will require…
Over the next 6 years the CDF and D0 collaborations have the goal of collecting 15 fb-1 of data in collider Run II. This will require a number of ambitious upgrades to the Fermilab accelerator complex, some of which have been completed,…
Between Run II commissioning in early 2001 and the end of operations in September 2011, the Tevatron collider delivered 12~fb$^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV to the Collider Detector at Fermilab (CDF). During that…
Results on diffraction obtained by the CDF Collaboration in Run I of the Fermilab Tevatron $\bar pp$ collider are reviewed. New results are reported on soft double diffraction and diffractive $J/\psi$ production. The CDF program for…
Run 2 of the Tevatron collider at Fermilab has begun in the spring of 2001. During its first year of operation the Tevatron has delivered a luminosity of approximately 30/pb to the Dzero experiment. These data have been used to commission…
The Fermilab Tevatron collider's data-taking run ended in September 2011, yielding a dataset with rich scientific potential. The CDF and D0 experiments each have approximately 9 PB of collider and simulated data stored on tape. A large…
We present results on hard diffraction obtained by the CDF Collaboration in Run II proton-antiproton collisions at the Fermilab Tevatron. Run I CDF results on hard diffraction are also reviewed.
After a hiatus of almost 6 years and an extensive upgrade, Tevatron, the world largest proton--antiproton collider, has resumed the operation for the so called RUN II. In this paper we give a brief overview of the many new features of the…
Results on soft and hard diffraction obtained by the CDF Collaboration in Run I of the Fermilab Tevatron pbar-p collider are reviewed and compared with results from the DESY e-p collider HERA and with theoretical expectations. In addition,…
Since the beginning of Run II at the Fermilab Tevatron, the QCD physics groups of the CDF and D0 experiments have worked to reach unprecedented levels of precision for many QCD observables. Thanks to the large dataset - over 3 fb^-1 of…
Recent performance of Fermilab's Tevatron has exceeded this year's design goals and further accelerator upgrades are underway. The high-luminosity period which follows these improvements is known as Run IIb. The D0 experiment is in the…
After a five year upgrade period, the Fermilab experiments CDF and DO are taking high quality data in Run II of the Tevatron Collider. We report on the start-up of both detectors and present a selection of first B physics results from the…
The Tevatron in Collider Run II (2001-present) is operating with six times more bunches and many times higher beam intensities and luminosities than in Run I (1992-1995). Beam diagnostics were crucial for the machine start-up and the…
The Tevatron Run II program is in progress since 2001. The CDF experiment have accumulated roughly five times more data than in Run I, with much improved detectors. Preliminary results from the CDF experiment are presented. We focus on the…
