The mass of the scalar boson is set to $m_{\\phi}=125$ GeV and its coupling to top-quarks is varied such that $\\alpha=$ 0$^\\circ$, 22.5$^\\circ$, 45.0$^\\circ$, 67.5$^\\circ$, 90.0$^\\circ$, 135.0$^\\circ$ and 180.0$^\\circ$. Dileptonic final states of the $t\\bar{t}\\phi$ system are used, with the scalar boson decaying as $\\phi\\rightarrow b\\bar{b}$.
