A test of the flavor independence of strong interactions

PDF Version Also Available for Download.

Description

The authors present a comparison of the strong couplings of b, c, and light (u, d, and s) quarks derived from multi-jet rates in flavor-tagged samples of hadronic Z{sup 0} decays recorded with the SLC Large detector at the SLAC Linear Collider. By comparing the rates of 3-jet events in these three samples they have extracted: {alpha}{sub s}(uds)/{alpha}{sub s}(all) = 0.97 {+-} 0.03(stat.) {+-} 0.04(syst.) {+-} 0.02(theory), {alpha}{sub s}(c)/{alpha}{sub s}(all) = 1.12 {+-} 0.11(stat.) {+-} 0.10(syst.) {+-} 0.07(theory), {alpha}{sub s}(b)/{alpha}{sub s}(all) = 1.03 {+-} 0.04(stat.) {+-} 0.08(syst.) {+-} 0.02(theory).
