| Abstract: | Tevatron 目前正在研究t'→ bW 衰變，但由於 LHC 的到來，我們必須考慮更多的能量範圍。我們討論了當b'的質量小於tW門檻時的 b'→tW(∗) 及 t(∗)W b'衰變，並討論它們在b'的質量大於tW門檻時它們是如何變成 b'→tW。我們使用了convolution 方法來做五體衰變的計算。除了CDF探討的t→bW 我們亦討論了t'→b'(∗)W(∗)。 At the Tevatron, heavy t'→ bW decay is currently being searched for, but a broader spectrum should be explored at the LHC. We discuss the two branches of b'→tW(∗) and t(∗)W for b' below the tW threshold, and how it merges with b'→tW above threshold. We treat with convolution method and five body final state. A similar discussion is given for b'→t'(∗)W(∗) decay, and t'→b'(∗)W(∗) decay, besides the t'→bW considered by CDF. |
