enter image description here

I tried to use tikzpicture and made something "by hand" (even knowing that that wasn't the better way), but I was not able to find a way to have the exactly result, especially in the middle of the text as the image above. My code:

documentclass{article}

usepackage{tikz-qtree}



begin{document}

    begin{tikzpicture}

    Tree [.A edge[roof]; {$alpha_{1} ldots alpha_{n}$} ]

    end{tikzpicture}

end{enumerate}
