Special Experimental HEP Seminar OBSERVATION of TOP QUARK PRODUCTION AT CDF ------------------------------------------ Prof. Pekka Sinervo University of Toronto MP203 Thursday, March 2, 1995 3:00-3:30 PM Abstract The latest results of the top quark search by the CDF experiment at the Fermilab Tevatron Collider will be presented. The new data shows clear signals for top quark production, confirming the existence of this new, massive fermion. A new estimate of the top quark mass and production cross section will be presented.
