Threshold Effects in the Decay of Heavy b' and t' Quarks

Yuan Chao, Kai-Feng Chen, Shing-Kuo Chen +3

A sequential fourth generation is still viable, but the t' and b' quarks are constrained to be not too far apart in mass. The t'{\to}bW and b'{\to}tW decay channels are still being…

Heavy b' and t' Decay

Yuan Chao, Kai-Feng Chen, Shing-Kuo Chen +3

Heavy $t^{'} \to bW$ is currently being searched for at the Tevatron, but a broader spectrum should be explored at the LHC. For $m_{b^{'}} < m_{t^{'}}$ , we discuss the two decay branches, $…
