Title: Direct detection constraints on dark photon dark matter

Abstract

Dark matter detectors built primarily to probe elastic scattering of WIMPs on nuclei are also precise probes of light, weakly coupled, particles that may be absorbed by the detector material. In this paper, we derive constraints on the minimal model of dark matter comprised of long-lived vector states V (dark photons) in the 0.01–100KeV mass range. The absence of an ionization signal in direct detection experiments such as XENON10 and XENON100 places a very strong constraint on the dark photon mixing angle, down to Ο(10^–15), assuming that dark photons comprise the dominant fraction of dark matter. This sensitivity to dark photon dark matter exceeds the indirect bounds derived from stellar energy loss considerations over a significant fraction of the available mass range. As a result, we also revisit indirect constraints from V → 3γ decay and show that limits from modifications to the cosmological ionization history are comparable to the updated limits from the diffuse γ-ray flux.

New constraints and prospects for sub-GeV dark matter scattering off electrons in xenon

Journal Article Essig, Rouven ; Volansky, Tomer ; Yu, Tien-Tien - Physical Review D

We study in detail sub-GeV dark matter scattering off electrons in xenon, including the expected electron recoil spectra and annual modulation spectra. We derive improved constraints using low-energy XENON10 and XENON100 ionization-only data. For XENON10, in addition to including electron-recoil data corresponding to about 1–3 electrons, we include for the first time events corresponding to about 4–7 electrons. Assuming the scattering is momentum independent (F_DM = 1 ), this strengthens a previous cross-section bound by almost an order of magnitude for dark matter masses above 50 MeV. The available XENON100 data corresponds to events with about 4–50 electrons, and leadsmore »« less

XENON10/100 dark matter constraints in comparison with CoGeNT and DAMA: Examining the L{sub eff} dependence

Journal Article Savage, Christopher ; Gelmini, Graciela ; Gondolo, Paolo ; ... - Physical Review. D, Particles Fields

We consider the compatibility of DAMA/LIBRA, CoGeNT, XENON10 and XENON100 results for spin-independent (SI) dark matter weakly interacting massive particles, particularly at low masses ({approx}10 GeV), assuming a standard dark matter halo. The XENON bounds depend on the scintillation efficiency factor L{sub eff} for which there is considerable uncertainty. Thus we consider various extrapolations for L{sub eff} at low energy. With the L{sub eff} measurements we consider, XENON100 results are found to be insensitive to the low-energy extrapolation. We find the strongest bounds are from XENON10, rather than XENON100, due to the lower energy threshold. For reasonable choices of L{submore »« less

Searching for dark absorption with direct detection experiments

Journal Article Bloch, Itay M. ; Essig, Rouven ; Tobioka, Kohsaku ; ... - Journal of High Energy Physics (Online)

We consider the absorption by bound electrons of dark matter in the form of dark photons and axion-like particles, as well as of dark photons from the Sun, in current and next-generation direct detection experiments. Experiments sensitive to electron recoils can detect such particles with masses between a few eV to more than 10 keV. For dark photon dark matter, we update a previous bound based on XENON10 data and derive new bounds based on data from XENON100 and CDMSlite. We find these experiments to disfavor previously allowed parameter space. Moreover, we derive sensitivity projections for SuperCDMS at SNOLAB formore »« less

Revisiting XENON100's constraints (and signals?) for low-mass dark matter

Journal Article Hooper, Dan - Journal of Cosmology and Astroparticle Physics

Although observations made with the CoGeNT and CDMS experiments have been interpreted as possible signals of low-mass ( ∼ 7–10 GeV) dark matter particles, constraints from the XENON100 collaboration appear to be incompatible with this hypothesis, at least at face value. In this paper, we revisit XENON100's constraint on dark matter in this mass range, and consider how various uncertainties and assumptions made might alter this conclusion. We also note that while XENON100's two nuclear recoil candidates each exhibit very low ratios of ionization-to-scintillation signals, making them difficult to attribute to known electronic or neutron backgrounds, they are consistent withmore »« less

Technical Report Cabrera, Blas ; Gratta, Giorgio

Dark Matter Search - During the period of performance, our group continued the search for dark matter in the form of weakly interacting massive particles or WIMPs. As a key member of the CDMS (Cryogenic Dark Matter Search) collaboration, we completed the CDMS II experiment which led the field in sensitivity for more than five years. We fabricated all detectors, and participated in detector testing and verification. In addition, we participated in the construction and operation of the facility at the Soudan Underground Laboratory and played key roles in the data acquisition and analysis.
