CDFII Experiment (E835)
1. Goal of the experiment
The improved Collider Detector at Fermilab (CDFII) measures most features of
physics interest of proton-antiproton interactions at the Fermilab Tevatron Collider, at a
c.m.s. energy of about 2 TeV. The Tevatron is the highest energy particle accelerator in
the world, and the only hadron collider. The main goal of the so-called "run2" that started
in March 2001 is to discover new physics beyond what is understood in the framework of
the Standard Model of Elementary Particles. In addition, a difficult but not impossible
goal is to discover a low mass Higgs boson (mass less than about 180 GeV/c2), which is
the last unexplored feature of the Standard Model. Accurate measurements will be made
of heavy flavor (top, beauty) production and decay properties, including Bs oscillations
and search for CP violation effects in the B-sector. Most properties of events with W,Z
bosons, large energy jets, and diffractive topology will be measured with precision
limited only by systematics.
2. Publications of the year 2001
The analysis of data collected in run1 (1992-1995) continued to produce important
results. 18 publications in the Phys.Rev. and Phys.Rev.Lett. have reported measurements
on features of top quark production, beauty hadron properties, hadron jet and hadron
interaction physics, electroweak physics, and on searches for non-standard model
phenomena.
The list of the 2001 publications is attached.
3. Plan for the years 2002-2004
The Tevatron Collider run2 is expected to last for about 7 years, and it is
conventionally split into period a) and period b).
During period a) data will be collected with minimal interrumptions for maintenance
and repairs till end of 2004. The goal is for the Tevatron to deliver to CDF an integrated
luminosity of 2fb**(-1).
Besides sharpening the entire set of its previous studies, by analysing these data CDF
aims at measuring several new phenomena, noticeably the oscillation frequency of the
neutral strange B-hadron, CP symmetry violation effects in hadronically decaying Bhadrons, and to gather significant information on the possible existence of the Higgs
boson below 130 GeV in mass.
Funding foreseen in the 2002 Budget: 1833 kEuro
