An Improved Torsion Balance Test of the Equivalence Principle Towards the Sun
M. P. Ross, E. A. Shaw, C. Gettings +3
We search for violations of the Equivalence Principle towards the Sun using a rotating torsion balance apparatus. We set 95\%-confidence limits on violations with beryllium and alu…

Probing For Non-Gravitational Galactic-Range Dark Matter Interactions
M. P. Ross, S. K. Apple, E. A. Shaw +3
Dark matter remains a mystery in fundamental physics. The only evidence for dark matter's existence is from gravitational interactions. We operated a precision torsion balance expe…
