The Brownian loop soup is a conformally invariant statistical ensemble of random loops in two dimensions characterized by an intensity, with central charge. Recent progress resulted in an analytic form for the four-point function of a class of scalar conformal primary “layering vertex operators”with dimensions, with, that compute certain statistical properties of the model. The Virasoro conformal block expansion of the four-point function revealed the existence of a new set of operators with dimensions, for all non-negative integerssatisfying. In this paper we introduce the edge counting fieldthat counts the number of loop boundaries that pass close to the pointz. We rigorously prove that then-point functions ofare well defined and behave as expected for a conformal primary field with dimensions (1/3, 1/3). We analytically compute the four-point function \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\left\langle {\mathcal {O}_{\beta }(z_1) \mathcal {O}_{-\beta }(z_2) \mathcal {E}(z_3) \mathcal {E}(z_4)}\right\rangle $$\end{document} and analyze its conformal block expansion. The operator product expansions ofandcontain higher-order edge operators with “charge”and dimensions. Hence, we have explicitly identified all scalar primary operators among the new set mentioned above. We also re-compute the central charge by an independent method based on the operator product expansion and find agreement with previous methods.
