Resumé

We investigate the maximum coding rate achievable
on a two-user broadcast channel for the case where a common-
message is transmitted using fixed-blocklength codes with feed-
back. Specifically, we focus on a family of broadcast channels com-
posed of two antisymmetric Z-channels. For this setup, we obtain
matching upper and lower bounds on the dispersion term in the
asymptotic expansion of the maximum coding rate. These bounds
reveal that the dispersion is halved compared to the no-feedback
case
