Abstract

The fractional partial width of the Z⁰ to b quarks, {Mathematical expression}, has been measured by OPAL using an impact parameter technique. The method has been developed using 130 000 hadronic events collected by OPAL in 1990. We find: {Mathematical expression} The measurement assumes the relative rates of the Z⁰ to uds and c quarks given by the Standard Model. Varying the charm fraction from the Standard Model value of {Mathematical expression} changes the result by an additional {Mathematical expression}.

N2 - The fractional partial width of the Z0 to b quarks, {Mathematical expression}, has been measured by OPAL using an impact parameter technique. The method has been developed using 130 000 hadronic events collected by OPAL in 1990. We find: {Mathematical expression} The measurement assumes the relative rates of the Z0 to uds and c quarks given by the Standard Model. Varying the charm fraction from the Standard Model value of {Mathematical expression} changes the result by an additional {Mathematical expression}.
