TL;DR: The results of the Eoetvoes-Pekar-Fekete data are sensitive to the composition of the materials used, and that their results support the existence of an intermediate-range coupling to baryon number or hypercharge.
Abstract: We have carefully reexamined the results of the experiment of E\"otv\"os, Pek\'ar, and Fekete, which compared the accelerations of various materials to the Earth. We find that the E\"otv\"os-Pek\'ar-Fekete data are sensitive to the composition of the materials used, and that their results support the existence of an intermediate-range coupling to baryon number or hypercharge.

TL;DR: In this paper, the results of the experiment of Eotvos, Pekar, and Fekete were re-examined, and it was shown that the results were sensitive to the composition of the materials used, and that their results support the existence of an intermediate-range coupling to baryon number or hypercharge.

TL;DR: It is shown that ..gamma../sub Y/ is best detected as an unobserved neutral in the decays K/sup + -/..--> pi../sup +-/..gamma\.sub Y/, and that existing experimental limits provide nontrivial constraints on the strength and range of possible hypercharge couplings.
Abstract: We discuss experiments for detecting hyperphotons (..gamma../sub Y/), which are the real quanta of a hypercharge field whose existence has been suggested by a recent reanalysis of the Eoetvoes experiment. It is shown that ..gamma../sub Y/ is best detected as an unobserved neutral in the decays K/sup + -/..--> pi../sup + -/..gamma../sub Y/ and K/sub S//sup 0/..--> pi../sup 0/..gamma../sub Y/, and that existing experimental limits provide nontrivial constraints on the strength and range of possible hypercharge couplings.

TL;DR: In this paper, the authors present a phenomenological description of the "fifth force" which focuses on the implications of the existing data from satellite and geophysical measurements of gravity, the Eoetvoes experiment, decays into hyperphotons, and the energy-dependence of the K/sup 0/ -anti K/Sup 0/ parameters.

TL;DR: In this article, a review of experimental and theoretical work dealing with the proposed fifth force is presented, with no challenges to the original assertion that these data evidence a correlation characteristic of the presence of a new coupling to baryon number or hypercharge.
Abstract: We review recent experimental and theoretical work dealing with the proposed fifth force. Further analysis of the original Eotvos experiments has uncovered no challenges to our original assertion that these data evidence a correlation characteristic of the presence of a new coupling to baryon number or hypercharge. Various models suggest that the proposed fifth force could be accomodated naturally into the existing theoretical framework.
