    Publicado 2016
    “…Dark Matter (DM) comprising particles in the mass range of a few MeV to GeV is waiting to be explored, given the many theoretical models accommodating cosmological abundance. We hereby propose an experiment with the LHC proton beam of 7 TeV striking onto the beam dump target, emitting neutrinos and possibly, Dark Matter candidates. …”

    “…From  a basic physics perspective, exquisitely sensitive measurements have constrained the nature of dark matter, the cosmological origin of magnetic field and the properties of black holes. …”

    “…This volume law contribution is related to the thermal properties of de SItter space and leads to a total entropy inside the static patch that precisely matches the Bekenstein-Hawking formula for the cosmological horizon. We study the effect of this extra contribution in the derivation of the emergent laws of gravity, and argue that it leads to a modification compared to Einstein gravity. …”

    “…Additionally when looking at the differences with classical mechanics, quantum mechanics crucially depends on the value of Planck's constant h. Recent cosmological observations tend to indicate that not only the fine structure constant α but also h might have varied in both time and space since the Big Bang. …”

    “…It turned out that the understanding of elementary particles and the forces acting between them is extremely relevant for our perception of the cosmological development. Quite often scientific research is supported because it is the basis for technical progress and for the material well-being of humans. …”

    “…Fortunately, high-energy astrophysical neutrinos, with TeV–PeV energies and cosmological-scale baselines, provide us with a unique opportunity to do so; by looking for the differences in the distribution of arrival directions of neutrinos of different flavours. …”

    “…The most sensitive experiment - since eight years the HEIDELBERG-MOSCOW experiment in Gran-Sasso - already now, with the experimental limit of $<m_\nu > < 0.26$ eV practically excludes degenerate $\nu$ mass scenarios allowing neutrinos as hot dark matter in the universe for the smallangle MSW solution of the solar neutrino problem. It probes cosmological models including hot dark matter already now on the level of future satellite experiments MAP and PLANCK. …”

    Publicado 2003
    “…Alternatively, we consider the possibility that a large fraction of the ultrahigh energy cosmic rays are decay products of Z bosons which were produced in the scattering of ultrahigh energy cosmic neutrinos on cosmological relic neutrinos. Based on this scenario we determine the required mass of the heaviest relic neutrino. …”

    “…After reviewing previous experimental limits on the mass of the Higgs boson, a speculative cosmological argument for a small mass is given. The reactions and decays in which a Higgs boson should occur, for various values of its mass, are described. …”

    “…A consequence of this fact is probably that BL Lac nuclei suffer a smaller cosmological evolution than do the Seyfert 1 nuclei (or quasars), as suspected by Setti and Woltjer (1977), as the surface density of faint BL Lac objects is much smaller than that of quasars. …”

    “…The data from the first run of the LHC at 7 and 8 TeV, together with the information provided by other experiments such as precision electroweak measurements, flavour measurements, the cosmological density of cold dark matter and the direct search for the scattering of dark matter particles in the LUX experiment, provide important constraints on supersymmetric models. …”

    “…The increased numbers of GRB afterglows, GRB-supernova detections, redshifts and host galaxy associations has greatly improved our understanding of what produces and powers these immense, cosmological explosions. Nevertheless, more high-quality data often also reveal greater complexity. …”
