The GAPS experiment: Low-energy antinuclei measurements for dark matter searches

EPJ Web of Conferences, 2023
GAPS (General Anti-Particle Spectrometer) is a balloon-borne experiment designed to measure low-energy (<0.25 GeV/n) cosmic antinuclei (i.e., antiprotons, antideuterons, and antihelium nuclei) as a signature of dark matter annihilation or decay.

Signatures of Dark Radiation in Neutrino and Dark Matter Detectors

, 2017
We consider the generic possibility that the Universe's energy budget includes some form of relativistic or semi-relativistic dark radiation (DR) with non-gravitational interactions with Standard Model (SM) particles.

Constraining Dark Energy with Clusters: Complementarity with Other Probes

, 2009
The Figure of Merit Science Working Group (FoMSWG) recently forecast the constraints on dark energy that will be achieved prior to the Joint Dark Energy Mission (JDEM) by ground-based experiments that exploit baryon acoustic oscillations, type Ia ...

HI Structure Observations of Reionization and Dark Energy

, 2008
This proceeding concentrates on the BAO signature of dark energy, and how the SKA dark energy case has been complicated by the emergence of HI structure experiments modeled after the Epoch of Reionization observatories. The purpose of the conference talk

Direct deflection of Millicharged radiation

Journal of High Energy Physics
Millicharged particles are generic in theories of dark sectors. A cosmic or local abundance of them may be produced by the early universe, stellar environments, or the decay or annihilation of dark matter/dark energy.

An explanation of one-loop induced h→μτ decay

Physics Letters B, 2016
We discuss a possibility to explain the excess of h→μτ at one-loop level. We introduce three generations of vector-like lepton doublet L′ and two singlet scalars S1,2 which are odd under Z2, while all the standard model fields are even under this ...

Exothermic Dark Matter

, 2010
We propose a novel mechanism for dark matter to explain the observed annual modulation signal at DAMA/LIBRA which avoids existing constraints from every other dark matter direct detection experiment including CRESST, CDMS, and XENON10.

Solar neutrinos in cryogenic detectors

European Physical Journal C: Particles and Fields
Coherent elastic neutrino-nucleus scattering (CE $$\nu $$ ν NS) poses an irreducible background in the search for dark matter-nucleus elastic scatterings, which is commonly known as the neutrino floor.

Topological freeze-out by semi-annihilation

Journal of High Energy Physics
We point out that a QCD-like dark sector can be coupled to the Standard Model by gauging the topological Skyrme current, which measures the dark baryon number in the infrared, to give a technically natural model for dark matter.

Luminous Dark Matter

, 2010
We propose a dark matter model in which the signal in direct detection experiments arises from electromagnetic, not nuclear, energy deposition. This can provide a novel explanation for DAMA while avoiding many direct detection constraints.
