Angular Correlations in Associated Production of Single Top and Higgs with and without anomalous $Wtb$ Couplings

We study the angular correlation and the amount of top quark polarization in the production of a higgs boson in association with a single top quark in the $t-$channel at the LHC. We also study the effect of anomalous $Wtb$ couplings on the angular correlation and on the production cross section of the process. The cross section and angular correlation is almost insensitive to the variation of the Higgs boson mass within 3 GeV. The robustness of the angular correlation against the center-of-mass energy of the proton-proton collision, the variation of parton distribution functions, and the change of factorization scale is investigated. The sensitivity of this process to the anomalous couplings is examined.
