Effects on QCD in $R_b$ and $R_c$
The combined LEP and SLD measurements of R b are about three standard deviations above the standard model. The measurement techniques employed are claimed to be highly reliable and systematically safe. R c , which is measured using different and inherently less reliable techniques, is found to be 1....
