This paper summarizes a variety of recent results on heavy quark production and decay. Considerable progress has been made by CDF and D0 in measuring top quark production and decay properties. The top quark mass been measured with an uncertainty that is less than 3%, a relative precision that is better than has been achieved for other quarks. Measurements of the top production and decay properties are consistent with the Standard Model predictions, but are generally limited in precision by the small number of top quark events in the present data samples. ALEPH and CLEO have measured the branching ratio for the flavor changing neutral current decay b→s[gamma] and find good agreement with the standard model. Measurements of B-quark production cross sections in p{anti p} collisions by CDF and D0 and in ep collisions by H1 continue to show discrepancies between theory and experiment. CDF and DELPHI have measured the b-quark fragmentation fractions with better accuracy than previous measurements. Finally, measurements of charmonium production by D0, E771, and L3 are consistent with predictions of the color octet model.

Experiments at SLC and LEP have made preliminary measurements of the relative partial widths of the c and b quarks. Using D* tagging, DELPHI has found R{sub c}{bar c}{triple bond}/[Gamma]{sub c}{bar c}/[Gamma]{sub hadr.} = 0.162 {plus minus} 0.032 {plus minus} 0.031, in good agreement with the Standard Model value of 0.171. ALEPH has used semileptonic decays of charm to obtain 0.148 {plus minus} 0.044 {sub -0.038}{sup +0.045}. Three experiments have used semileptonic [Beta] decays to measurement R{sub b}{bar b}: R{sub b}{bar b} = 0.23 {plus minus} 0.10 (Mark II), 0.218 {plus minus} 0.010 {plus minus} 0.021 (L3), and 0.220 {plus minus} 0.016 {plus minus} 0.024 (ALEPH). All agree well with the expected value of 0.217. The uncertainty in branching ratios of c and b hadrons is the largest systematic error in all of the results. Future LEP measurements of the branching ratios may reduce the errors. R{sub b}{bar b} will also be measured with different, and possibly lower, systematic errors by Mark II using impact parameter tagging.
