标题： Singlet-Higgs-Boson Signals at Hadron Colliders

摘要： 许多标准模型的扩展包含$SU(2)_L \times U(1)_Y$个单态希格斯玻色子，$h^0$，以及与之耦合的矢量样费米子。 考虑了在不同矢量样费米子情景下，这类单态中性标量在强子对撞机上的产生和探测可能性。 我们发现，对于某些质量与耦合值， 在欧洲核子研究中心大型强子对撞机（LHC）上探测似乎是一种明确的可能性，而在费米国家加速器实验室顶夸克探测器升级版上，$h^0$只有在非常有利的情况下才可能被观测到。 显示英文摘要

摘要： Many extensions of the Standard Model include $SU(2)_L \times U(1)_Y$ singlet higgs bosons, $h^0$, and also vectorlike fermions which couple to it. The production and detection possibilities of such singlet neutral scalars at hadron colliders are considered for different scenarios of vectorlike fermions. We find that for some values of masses and couplings, detection at the CERN Large Hadron Collider (LHC) appears to be a distinct possibility, while at the Fermilab Tevatron upgrade the $h^0$ might be observed only in very favourable circumstances.
