Title: SERIES OF INFORMAL DISCUSSIONS ON CONFORMAL LOOP ENSEMBLES Abstract: This second background discussion continues the calculation of the Radon-Nikodym derivative of chordal SLE curves in different domains, and giving an expression for it in terms of the Brownian loop soup. The definitions that are needed from the first discussion are those of the half-plane capacity and of the Brownian bubble measure in the half-plane at 0. We will also still make use of It? calculus, Girsanov's theorem as well as the formulas we had for the measure of bubbles that exit a given subdomain.
