Two\nimportant scales emerge, one set by the kinematics and one set by the dynamics.\nThis method also provides two approximate analytic formulas useful for\nnumerical evaluation of entanglement and reveals an interesting connection\nbetween purity, linear coordinate transformations, and momentum ...

constraining the locations of the marked points. Subsequent integrals agree with the field-theoretic box diagram for the four-point amplitude, in accordance with the divergent $epsilon$ expansions derived from dimensional regularization in the infrared limit. We conclude by highlighting potential avenues ...
