Not sure where this particular question belongs.
Do you know of any Cavendish type measurements of G, in which the mass (and ~density) of the attractors (gravitational sources) are controls, and the number of particles (fermions or maybe quarks+leptons) is the independent variable?
The Eöt-Wash group has done Eötvös style tests of the WEP using test bodies of the same mass/density with different baryon/mass ratios, but this was a test of the WEP.
I haven't been able to find any information about experiments to test whether gravitational acceleration (warping of spacetime) is more closely correlated with the number of particles of an attractor, or the mass of the attractor.
Thanks,
Matt
