Indications of a Fifth Force Coupling to Baryon Number in the Potter Test of the Weak Equivalence Principle
Megan H. McDuffie, Ephraim Fischbach, Dennis E. Krause +4
We have reanalyzed data obtained by Potter in a 1923 experiment aimed at testing whether the accelerations of test masses in the Earth's gravitational field are independent of thei…
Some Recent Developments in 5th Force Searches
Ephraim Fischbach, Dennis E. Krause, Megan H. McDuffie +1
Recently we drew attention to the fact that most recent 5th force searches and tests of the weak equivalence principle (WEP) utilize only one or two pairs of test samples. We argue…
Significance of Composition-Dependent Effects in Fifth-Force Searches
Ephraim Fischbach, John T. Gruenwald, Dennis E. Krause +3
Indications of a possible composition-dependent fifth force, based on a reanalysis of the Eötvös experiment, have not been supported by a number of modern experiments. Here, we arg…
Generalized Analysis of the Eötvös Experiment
M. J. Mueterthies, E. Fischbach, V. E. Barnes +3
We present a generalized phenomenological formalism for analyzing the original Eötvös experiment in the presence of gravity and a generic "5th force." To date no evidence for a 5th…
Is there a signal for Lorentz non-invariance in existing radioactive decay data?
M. J. Mueterthies, D. E. Krause, A. Longman +2
Measurements of the beta decay rates of nuclei have revealed annual periodicities with approximately the same relative amplitude even though the half-lives range over nine orders o…
