  Would the solutions from here be good? tex.stackexchange.com/questions/7032/… Or is there something you require that those can't do?

  From that page especially tex.stackexchange.com/a/7045 might be interesting, it is easy with TikZ to make dashed lines as in the example in this question.

All the answers linked to in the comments were written before tikzmarknode got added to the tikzmark library. With this addition, it is IMHO particularly straightforward to get something like this.

documentclass{article}

usepackage{amsmath,amssymb}

usepackage{tikz}

usetikzlibrary{tikzmark}

begin{document}

[mathrm{i}int!mathrm{d}t,mathrm{d}theta,mathrm{d}bartheta,

tikzmarknode[circle,draw,dashed,inner sep=2pt]{tc}{dfrac{thetabartheta}{hbar}}

left(L[Phi]+mathbb{J}right)]

end{document}

Of course, you could do much more with tikzmarknode.

documentclass[fleqn]{article}

usepackage{amsmath,amssymb}

usepackage{tikz}

usetikzlibrary{tikzmark}

tikzset{dashed circle/.style={circle,draw,dashed,inner sep=2pt}}

begin{document}

The conventional dots

begin{equation}label{eq:conventional}

 mathcal{Z}[mathbb{J}]=expleft[mathrm{i}int!mathrm{d}t,mathrm{d}theta,mathrm{d}bartheta,

 tikzmarknode[dashed circle]{11}{1}

 left(L[Phi]+mathbb{J}right)right];.

end{equation}

The modified dots

begin{equation}

 mathcal{Z}'[mathbb{J}]=expleft[mathrm{i}int!mathrm{d}t,mathrm{d}theta,mathrm{d}bartheta,

 tikzmarknode[dashed circle]{tc1}{dfrac{thetabartheta}{hbar}}

 left(L[Phi]+mathbb{J}right)right];.label{eq:Z'}

end{equation}

eqref{eq:conventional} except that $tikzmarknode[dashed circle]{12}{1}$ got replaced by 

$tikzmarknode[dashed circle]{tc2}{dfrac{thetabartheta}{hbar}}$ in eqref{eq:Z'}.

begin{tikzpicture}[overlay,remember picture]

draw[red,latex-latex,thick] (tc1) to[bend left=10] (tc2);

end{tikzpicture}
