Title: Phenomenological constraints on low-scale gravity

Abstract

We study the constraints on gravity scale M{sub P} in extra-dimension gravitational theory, obtained from gravity-induced processes. The obtained constraints are subdivided into strong (though not robust) and reliable (though less strong). The strong constraints can be in principle relaxed due to some broken gauge symmetries, e.g. family symmetry. The strongest constraint is given by neutrino oscillations. For different assumptions the lower bound on M{sub P} is 10{sup 15}-10{sup 18} GeV. However, it can be, in principle, reduced by broken family symmetry. More reliable bounds are due to flavor-conserved operators or those which change the flavors within one family. These bounds, obtained using the electron mass and width of {pi}{yields}e{nu} decay, are 1x10{sup 5} GeV and 5x10{sup 5} GeV, for these two cases, respectively.

  • We consider no-scale supergravity inspired scenarios, where the gravitino mass and related soft supersymmetry-breaking parameters are determined dynamically by radiative corrections to an essentially flat tree-level potential in the supersymmetry-breaking hidden sector. We examine the theoretical and phenomenological viability of such a mechanism, when including up-to-date calculations of the low-energy sparticle spectrum and taking into account the latest LHC results and other experimental constraints. We (re)emphasize the role of the scale-dependent vacuum energy contribution to the effective potential, in obtaining realistic no-scale electroweak minima, examining carefully the impact of boundary conditions and of variants of the minimization procedure. We alsomore » discuss and implement the B{sub 0} (soft breaking Higgs mixing parameter) input boundary condition at high scale, therefore fixing tan{beta}(B{sub 0}) at low scales. For general high-scale boundary conditions with B{sub 0},m{sub 0},{center_dot}{center_dot}{center_dot}{ne}0, our analysis provides theoretical correlations among the supersymmetric, soft, and vacuum energy parameters and related phenomenological consequences at the LHC. For instance, a zero vacuum energy at the grand unified theory scale would lead to a decoupled supersymmetric spectrum, together with a light standard-model-like Higgs boson at the electroweak scale. Given the experimental exclusion limits, a substantial class of the boundary conditions, and, in particular, the strict no-scale with m{sub 0}=A{sub 0}=B{sub 0}=0, are only compatible with a stau being the lightest Minimal Supersymmetric Standard Model particle. Then, an enlarged allowed parameter space emerges when assuming a gravitino lightest supersymmetric particle to account for the observed dark matter relic density.« less

  • We study cosmological constraints on metric f(R) gravity models that are designed to reproduce the ΛCDM expansion history with modifications to gravity described by a supplementary cosmological freedom, the Compton wavelength parameter B0. We conduct a Markov chain Monte Carlo analysis on the parameter space, utilizing the geometrical constraints from supernovae distances, the baryon acoustic oscillation distances, and the Hubble constant, along with all of the cosmic microwave background data, including the largest scales, its correlation with galaxies, and a probe of the relation between weak gravitational lensing and galaxy flows. The strongest constraints, however, are obtained through the inclusionmore » of data from cluster abundance. Using all of the data, we infer a bound of B 0<1.1×10 -3 at the 95% C.L.« less
  • In recent years, an energetic experimental program has set quite stringent limits on a possible ''non-1/r{sup 2}'' dependence on gravity at short length scales. This effort has been largely driven by the predictions of theories based on compactification of extra spatial dimensions. It is characteristic of many such theories that the strength and length scales of such anomalous gravity are not clearly determined from first principles. As a result, it is productive to extend the current limits the range and strength of such hypothetical interactions. As a heavy, neutral, and (almost) stable particle, the neutron provides an ideal probe formore » the study of such hypothetical interactions at very short range. In this work, we describe methods based on neutron interferometry which have the capability to provide improved sensitivity non-Newtonian forces down to length scales at and below an nanometer.« less
  • Galaxy-scale strong gravitational lenses with measured stellar velocity dispersions allow a test of the weak-field metric on kiloparsec scales and a geometric measurement of the cosmological distance-redshift relation, provided that the mass-dynamical structure of the lensing galaxies can be independently constrained to a sufficient degree. We combine data on 53 galaxy-scale strong lenses from the Sloan Lens ACS Survey with a well-motivated fiducial set of lens-galaxy parameters to find (1) a constraint on the post-Newtonian parameter gamma = 1.01 +- 0.05, and (2) a determination of OMEGA{sub L}AMBDA = 0.75 +- 0.17 under the assumption of a flat universe. Thesemore » constraints assume that the underlying observations and priors are free of systematic error. We evaluate the sensitivity of these results to systematic uncertainties in (1) total mass-profile shape, (2) velocity anisotropy, (3) light-profile shape, and (4) stellar velocity dispersion. Based on these sensitivities, we conclude that while such strong-lens samples can, in principle, provide an important tool for testing general relativity and cosmology, they are unlikely to yield precision measurements of gamma and OMEGA{sub L}AMBDA unless the properties of the lensing galaxies are independently constrained with substantially greater accuracy than at present.« less
