The Top Story

Abstract

This is an overview of top quark search, with particular emphasis on the more recent results. After a brief introduction to the basic constituents of matter and their interactions, I shall discuss the indirect evidences for the existence of top quark and its mass from LEP and finally the direct observation of a top quark signal recently reported from the Tevatron collider. I shall try to put these results in perspective and provide some insight into the physics issues involved in the top quark search.
