Discovering its fundamental nature has become one of the greatest outstanding problems in modern science. Other persistent problems in physics have lingered for decades, among them the electroweak hierarchy and origin of the baryon asymmetry. Little is known about the solutions to these problems except that they must lie beyond the Standard Model. The first half of this dissertation explores dark matter models motivated by their solution to not only the dark matter conundrum but other issues such as electroweak naturalness and baryon asymmetry.

It has been suggested that dark disks could explain a variety of observed phenomena, including periodic comet impacts. Using the first data release from the Gaia space observatory, we search for a dark disk via its effect on stellar kinematics in the Milky Way. Our new limits disfavor the presence of a thin dark matter disk, and we present updated measurements on the total matter density in the Solar neighborhood.

  • Multifield Inflation After Planck: the Case for Nonminimal Couplings
    Multifield Inflation after Planck: The Case for Nonminimal Couplings David I. Kaiser and Evangelos I. Sfakianakis∗ Center for Theoretical Physics and Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139 USA (Dated: January 8, 2014) Multifield models of inflation with nonminimal couplings are in excellent agreement with the recent results from Planck. Across a broad range of couplings and initial conditions, such models evolve along an effectively single-field attractor solution and predict values of the primordial spectral index and its running, the tensor-to-scalar ratio, and non-Gaussianities squarely in the observationally most-favored region. Such models also can amplify isocurvature perturbations, which could account for the low power recently observed in the CMB power spectrum at low multipoles. Future measurements of primordial isocurvature perturbations could distinguish between the currently viable possibilities. PACS numbers: 04.62+v; 98.80.Cq. Published in Phys. Rev. Lett. 112 (2014): 011302. Early-universe inflation remains the leading framework for understanding a variety of features of our observable universe [1, 2]. Most impressive has been the prediction of pri- mordial quantum fluctuations that could seed large-scale structure. Recent measurements of the spectral tilt of primordial (scalar) perturbations, ns, find a decisive departure from arXiv:1304.0363v3 [astro-ph.CO] 7 Jan 2014 a scale-invariant spectrum [3, 4]. The Planck collaboration's value, ns = 0:9603 ± 0:0073, differs from ns = 1 by more than 5σ. At the same time, observations with Planck constrain the ratio of tensor-to-scalar perturbations to r < 0:11 (95% CL), and are consistent with the absence of primordial non-Gaussianities, fNL ∼ 0 [4, 5].

    Light Dark Matter in Superfluid Helium: Detection with Multi-excitation Production Simon Knapen,1, 2 Tongyan Lin,1, 2 and Kathryn M. Zurek1, 2 1Theory Group, Lawrence Berkeley National Laboratory, Berkeley, CA 94709 USA 2Berkeley Center for Theoretical Physics, University of California, Berkeley, CA 94709 USA (Dated: November 23, 2016) Abstract We examine in depth a recent proposal to utilize superfluid helium for direct detection of sub-MeV mass dark matter. For sub-keV recoil energies, nuclear scattering events in liquid helium primarily deposit energy into long-lived phonon and roton quasiparticle excitations. If the energy thresholds of the detector can be reduced to the meV scale, then dark matter as light as MeV can be reached ∼ with ordinary nuclear recoils. If, on the other hand, two or more quasiparticle excitations are directly produced in the dark matter interaction, the kinematics of the scattering allows sensitivity to dark matter as light as keV at the same energy resolution. We present in detail the theoretical framework ∼ for describing excitations in superfluid helium, using it to calculate the rate for the leading dark matter scattering interaction, where an off-shell phonon splits into two or more higher-momentum excitations. We validate our analytic results against the measured and simulated dynamic response of superfluid helium. Finally, we apply this formalism to the case of a kinetically mixed hidden photon in the superfluid, both with and without an external electric field to catalyze the processes. arXiv:1611.06228v1 [hep-ph] 18 Nov 2016 1 CONTENTS I Introduction2 II Theory of superfluid helium5 A Bijl-Feynman relation for single-excitations .
