These correlation functions depend on multiple continuous parameters: the insertion points of the operators, the intensity of the soup, and the charges of the operators. In the case of the four-point function there is non-trivial dependence on five continuous parameters: the cross-ratio, the intensity, and three real charges. The four-point function is crossing symmetric. We analyze its conformal block expansion and discover a previously unknown set of new conformal primary operators.", "revisions": [ { "version": "v1", "updated": "2019-12-02T18:04:43.000Z" } ], "analyses": { "keywords": [ "brownian loop soup", "exact correlation functions", "four-point function", "two-point correlation function", "conformal block expansion" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable" } } }
