A review of short-range gravity experiments in the LHC era

Abstract: This document briefly reviews recent short-range gravity experiments that were performed at below laboratory scales to test the Newtonian inverse square law of gravity. To compare sensitivities of these measurements, estimates using the conventional Yukawa parametrization are introduced. Since these experiments were triggered by the prediction of the large extra-dimension model, experiments performed at different length scales are compared with this prediction. In this paper, a direct comparison between labora… Show more

“…This potential is very interesting because it regularises the divergent behaviour of Newton's potential at small distances. Furthermore, at scales where the deviations start to be important, it is similar to the potentials that have been considered to constrain the deviations from Newton's law at short distances [40,41,42] …”

“…[41][42][43] In addition, in 15,44,45 it was shown that from inflationary cosmology one obtains huge mass of dilaton: . A natural way to avoid the obvious strong tension between these very different estimates in the framework of MDG seems to be the assumption that in Nature we have a withholding dilatonic potential V (Φ) with several minima 7 that show up at different scales as different values of the dilaton mass m Φ .…”

“…Direct tests on deviation of the inverse square law at short distances, based on modern versions of torsionbalance instrument, have been used with the purpose of searching for signals of extra dimensions. In these experiments, the modified gravitational potential is parameterized as G M/r 1 + αe −r/λ , where, in the ADD model, α = 8n/3 and λ is equal to the radius R of the extra dimensions [35][36][37][38]. From the empirical constraints on α and λ, upper bounds for R are inferred for each value of n. For instance, for n = 1 and n = 2, the data imply that R < 44μm and R < 37μm, respectively, which corresponds (see, the relation between R and M D in the appendix) to M D > 3.6 TeV for n = 2 [37,57].…”
