\section{Executive Summary}

The CDF-II experiment is studying 2.0 TeV proton-antiproton (\ppbar)
collisions produced by the Fermilab Tevatron Collider, currently
the highest energy collider in the world.  The collider data taking
period known as Run II started in 2002 and, as of September 2005, 
the accelerator has delivered over 1~\invfb\, with an 
additional 3~\invfb\ expected by the end of 2007.  The analysis 
of these integrated luminosities represents an unprecedented 
scientific opportunity to explore the high energy frontier. 
The IPP-Canada group requests funding for the next 3 years 
to take advantage of this outstanding opportunity.

  IPP scientists have been supported by NSERC to 
participate in the CDF project since 1991, when the 
experiment was in preparation for a data-taking period 
known as Run I.  In anticipation of the large increase in 
luminosity we completed a major overhaul of the CDF 
sub-detectors and associated readout electronics, creating 
the new detector facility known as CDF-II. The Canadian 
hardware contribution to the CDF-II detector, funded through 
an NSERC equipment grant, focused on the silicon vertex 
detector support mechanics.  We have also made significant 
contributions to the Offline Project by developing most of 
the calorimetry reconstruction and simulation software.  
More recently, we committed the resources necessary to make 
our CFI-funded Beowulf cluster (450 2.4 GHz Xeon processors 
with approximately 30 TB of disk) the main Monte Carlo 
production facility for the CDF collaboration.  
 
  These NSERC and CFI-sponsored efforts have 
allowed us to play a very important role in the
experiment as is evidenced by the scientific 
productivity of our group and the leadership roles 
of our faculty and research associates. We have 
published and submitted more papers than other
groups of our size, including the first high-$P_T$
physics paper of Run II, the best single 
measurement of the top mass to date, and the first
measurement of the W boson mass in Run II.  The
leadership roles assumed by members of the 
group include Calorimetry group leader, Simulation 
Group leader, Head of Offline Operations, Silicon 
Detector Project leader, Offline Analysis 
leader, and Top and Electroweak Physics Group convener.   
Another important contribution of our group involves
the training of graduate students and research
associates in hadron collider physics. The Tevatron 
remains the ideal training ground for the next generation
of physicists that will work at the Large Hadron 
Collider.

 We intend to continue our effort on CDF in order
to capitalise scientifically on the Canadian 
contributions to CDF-II. The scientific programme for
the next three years showcases outstanding 
opportunities that include measurement of $B_s$ 
mixing, a first single top cross section measurement, 
precision electroweak measurements (W mass, top mass, etc.), 
precision measurements of top quark properties, and 
searches for new phenomena. Many of these measurements 
(e.g. $B_s$, single top, new phenomena like SUSY trileptons) 
will probably require integrated  luminosities beyond 2~\invfb\
with additional time required to understand the data thoroughly.

This proposal requests funding for the next 3 years in order
for the IPP group to capitalise fully on NSERC's significant 
investment in the CDF II experiment and its physics. 
This will allow our graduate students, research associates, and 
faculty to continue their service contributions to CDF and to 
complete their ongoing physics analyses at the exciting time 
when the scientific output of the experiment reaches its peak.
