我们研究了在强子对撞机上希格斯玻色子与单个顶夸克的产生。三个生产过程$（t$通道，S通道，W相关）在费米实验室Tevatron和欧洲核子研究中心大型强子对撞机（LHC）的横截面。我们研究了通过希格斯玻色子衰变到$B\overline{B}来检测这些过程中最大的一个信号的可能性，即大型强子对撞机的t通道过程。量子色动力学背景很大，难以抑制，阻碍了信号的提取。扩展我们的分析生产超对称希格斯玻色子也解决了。对于较大的$\mathrm{tan}\ensuremath{\beta}值，横截面得到增强，从而增加了提取信号的可能性。
We study the production of the Higgs boson in association with a single top quark at hadron colliders. The cross sections for the three production processes $(t$ channel, s channel, and W associated) at both the Fermilab Tevatron and the CERN Large Hadron Collider (LHC) are presented. We investigate the possibility of detecting a signal for the largest of these processes, the t-channel process at the LHC, via the Higgs boson decay into $b\overline{b}.$ The QCD backgrounds are large and difficult to curb, hindering the extraction of the signal. Extensions of our analysis to the production of supersymmetric Higgs bosons are also addressed. The cross section is enhanced for large values of $\mathrm{tan}\ensuremath{\beta},$ increasing the prospects for extracting a signal.
