极小和超极小Technicolor中的标量玻色子:质量、三线耦合和宽度
Scalar bosons in Minimal and Ultraminimal Technicolor: Masses, trilinear couplings and widths
摘要:
我们计算的质量,三线性自耦合和衰变宽度的标量复合玻色子的情况下,最小和Ultraminimal人工色模型的弱玻色子。通过贝特-萨尔彼得方程计算出的质量很轻,三线性耦合比与相同质量的基本标准模型标量玻色子相比所预期的要小。超极小模型标量玻色子衰变为电弱玻色子的宽度比极小模型小得多。
英文摘要:
We compute masses, trilinear self-couplings and decay widths into weak bosons of the scalar composite bosons in the case of the Minimal and Ultraminimal technicolor models. The masses, computed via the Bethe-Salpeter equation, turn out to be light and the trilinear couplings smaller than the one that would be expected when compared to a fundamental Standard Model scalar boson with the same mass. The decay widths into electroweak bosons of the Ultraminimal model scalars bosons are much smaller than the one of the Minimal model.
