The passage around this formula
What remains genuinely open, and OBSERVED nowhere yet, is whether the composite-mass instance of this estimator survives contact with a real interferometer once every recoil, laser, and path term the field already knows how to compute is included in full. The thirty-year dispute between Müller, Peters, and Chu on one side and Wolf, Blanchet, Bordé, Reynaud, Salomon, and Cohen-Tannoudji and Sinha and Samuel on the other was not a disagreement about mathematics; both sides agreed on the interferometer phase formula. It was a disagreement about which piece of a correct formula is allowed to be called a measurement of mass. Roura’s and Di Pumpo and collaborators’ answer — a narrow, differential,…
