The Top Quark: Experimental Roots and Branches of Theory

Even before the top quark was discovered by the CDF[1] and DØ[2] experiments in 1995, several of its properties could be deduced from those of its weak partner, the bottom quark. The increment in the measured[3] value of R = σ(e +e−→hadrons) σ(e+e−→μ+μ−) at the b threshold agreed with the predicted δR = 13 , confirmingQ b = − 1 3 . Likewise, data[4] on the front-back asymmetry for electroweak b...
