Title: SUSY dark matter: Beyond the standard paradigm

Abstract

Within the framework of the Minimal Supersymmetric Standard Model (MSSM), we explore a decoupling of the parameters into separate sectors that determine consistency with collider data, the abundance of dark matter, and potential signatures at direct dark matter searches. We consider weak-scale bino-like neutralino dark matter, and find that annihilations via light slepton exchange present a viable mechanism for obtaining the appropriate dark matter abundance assuming a thermal history. Constraints and prospects for discovery of these models are discussed, including the possibility that direct dark matter searches may be sensitive to these models if light squarks exhibit left-right mixing. Differences between the scenarios presented here and the typical expectations for the MSSM are discussed.

  • Considerations of massive neutrinos, baryogenesis, as well as fermion mass textures in the grand unified theory framework provide strong motivations for supersymmetric (SUSY) SO(10) as the theory beyond the standard model. If one wants to simultaneously accommodate the {nu}{sub {tau}} as the hot dark matter (HDM) of the universe, then this prefers the SO(10) theory to have an intermediate scale around 10{sup 10} to 10{sup 11} GeV. In this paper, we discuss examples of superstring-inspired SUSY SO(10) models with intermediate scales that are consistent with the low energy precision measurements of the standard model gauge couplings. The hypothesis of {italmore » b}-{tau} unification which is a successful prediction of many grand unified theories is then required of these models and the resulting prediction of the {ital b}-quark mass is used as a measure of the viability of these schemes. A detailed analysis of a model with a {ital v}{sub {ital B}{ital L}}{congruent}10{sup 11} GeV, which satisfies both the requirements of invisible axion and {nu}{sub {tau}} as HDM is presented and shown to lead to {ital m}{sub {ital b}}({ital m}{sub {ital b}}){congruent}4.9 GeV in the one-loop approximation.« less
  • The momentum transfer dependence of the total cross section for elastic scattering of cold dark matter candidates, i.e., lightest supersymmetric particles (LSP`s), with nuclei is examined. The presented calculations of the event rates refer to a number of representative nuclear targets throughout the periodic table and have been obtained in a relatively wide phenomenologically allowed SUSY parameter space. For the coherent cross sections it is shown that, since the momentum transfer can be quite big for a large mass of the LSP and heavy nuclei even though the energy transfer is small ({le}100 keV), the total cross section can inmore » such instances be reduced by a factor of about 5. For the spin-induced cross section of odd-A nuclear targets, as is the case of {sup 207}Pb studied in this work, we found that the reduction is less pronounced, since the high multipoles tend to enhance the cross section as the momentum transfer increases (for a LSP mass {lt}200 GeV) and partially cancel the momentum retardation. The effect of the Earth`s revolution around the Sun on these event rates is also studied by folding with a Maxwellian LSP-velocity distribution which is consistent with its density in the halos. We thus find that the convoluted event rates do not appreciably change compared to those obtained with an average velocity. The event rates increase with A and, in the SUSY parameter space considered, they can reach values up to 140 yr{sup {minus}1}kg{sup {minus}1} for Pb. The modulation effect, however, was found to be small (less than {plus_minus}5{percent}). {copyright} {ital 1997} {ital The American Physical Society}« less
  • The minimal supersymmetric extension of the standard model (MSSM) is a well-motivated theoretical framework, which contains an extended Higgs sector, including a light Higgs with standard model-like properties in most of the parameter space. Because of the large QCD background, searches for such a Higgs, decaying into a pair of bottom quarks, are very challenging at the LHC. It has been long realized that the situation may be ameliorated by searching for Higgs bosons in supersymmetric decay chains. Moreover, it has been recently suggested that the b{bar b} decay channel may be observed in standard production channels by selecting boostedmore » Higgs bosons, which may be easily identified from the QCD background. Such boosted Higgs bosons are frequent in the MSSM, since they are produced from decays of heavy colored supersymmetric particles. Previous works have emphasized the possibility of observing boosted Higgs bosons in the light Higgsino region. In this work, we study the same question in the regions of parameter space consistent with a neutralino dark matter relic density, analyzing its dependence on the nonstandard Higgs boson, slepton, and squark masses, as well as on the condition of gaugino mass unification. In general, we conclude that, provided sleptons are heavier than the second lightest neutralinos, the presence of boosted Higgs is a common MSSM feature, implying excellent prospects for observation of the light MSSM Higgs boson in the near future.« less
