| Abstract: | We discuss the polar angle decay distribution in the decay of on-shell and off-shell polarized (W, Z) gauge bosons into massive quark pairs. In particular for the off-shell decays in $H to left( {W,Z} right) + left( {W^* ,Z^* } right)left( { to q_1 ,vec q_2 } right)$ it is important to keep the masses of the charm and bottom quarks at their finite values since the scale of the problem is not set by m W,Z 2 but by the offshellness of the gauge boson which varies in the range (m 1 + m 2)2 ≤ q 2 ≤ (m H ? m W,Z )2. |
