Quadratic Mass Corrections of Order αs3 mq2/s to the Decay Rate of Z- and W- Bosons
Abstract
We analytically compute quadratic mass corrections of order αs3 mq2/s to the absorptive part of the (non-diagonal) correlator of two axial vector currents. This allows us to find the correction of order αs3 mq2/M2W to the (W -->hadrons) as well as similar corrections to (Z -->hadrons).
