Top Quark Mass Measurements at CDF
The mass of the top quark M_top is interesting both as a fundamental
parameter of the standard model and as an important input to precision
electroweak tests. The Collider Detector at Fermilab (CDF) has a robust program
of top quark mass analyses, including the most precise single measurement,
M_top = 173.4 +/- 2.8 GeV/c^2, using 680 pb^-1 of ppbar collision data. A
combination of current results from CDF gives M_top = 172.0 +/- 2.7 GeV/c^2,
surpassing the stated goal of 3 GeV/c^2 precision using 2 fb^-1 of data.
Finally, a combination with current D0 results gives a world average top quark
mass of 172.5 +/- 2.3 GeV/c^2.Comment: 8 pages, Contribution to Proceedings of the 41st Rencontres de
