Orbital Dynamics of the Solar Basin
Cara Giovanetti, Robert Lasenby, Ken Van Tilburg
We study the dynamics of the solar basin -- the accumulated population of weakly-interacting particles on bound orbits in the Solar System. We focus on particles starting off on Su…
Wake forces in a background of quadratically coupled mediators
Ken Van Tilburg
Two particles can exert forces on each other when embedded in a sea of weakly-coupled particles. These "wake forces'' occur whenever the source and target particles have quadratic…
First indirect detection constraints on axions in the Solar basin
William DeRocco, Shalma Wegsman, Brian Grefenstette +2
Axions with masses of order keV can be produced in great abundance within the Solar core. The majority of Sun-produced axions escape to infinity, but a small fraction of the flux i…
The Piezoaxionic Effect
Asimina Arvanitaki, Amalia Madden, Ken Van Tilburg
Axion dark matter (DM) constitutes an oscillating background that violates parity and time-reversal symmtries. Inside piezoelectric crystals, where parity is broken spontaneously,…
Dark Photons in the Solar Basin
Robert Lasenby, Ken Van Tilburg
Production of dark photons inside the Sun forms the basis for the most sensitive probes of such particles over a wide mass range. A small fraction of dark photons is emitted into g…
Stellar Basins of Gravitationally Bound Particles
Ken Van Tilburg
A new physical phenomenon is identified: volumetric stellar emission into gravitationally bound orbits of weakly coupled particles such as axions, moduli, hidden photons, and neutr…
Resonant absorption of bosonic dark matter in molecules
Asimina Arvanitaki, Savas Dimopoulos, Ken Van Tilburg
We propose a new class of bosonic dark matter (DM) detectors based on resonant absorption onto a gas of small polyatomic molecules. Bosonic DM acts on the molecules as a narrow-ban…
Search for light scalar dark matter with atomic gravitational wave detectors
Asimina Arvanitaki, Peter W. Graham, Jason M. Hogan +2
We show that gravitational wave detectors based on a type of atom interferometry are sensitive to ultralight scalar dark matter. Such dark matter can cause temporal oscillations in…
Sound of Dark Matter: Searching for Light Scalars with Resonant-Mass Detectors
Asimina Arvanitaki, Savas Dimopoulos, Ken Van Tilburg
The fine-structure constant and the electron mass in string theory are determined by the values of scalar fields called moduli. If the dark matter takes on the form of such a light…
Searching for dilaton dark matter with atomic clocks
Asimina Arvanitaki, Junwu Huang, Ken Van Tilburg
We propose an experiment to search for ultralight scalar dark matter (DM) with dilatonic interactions. Such couplings can arise for the dilaton as well as for moduli and axion-like…
The Last Vestiges of Naturalness
Asimina Arvanitaki, Masha Baryakhtar, Xinlu Huang +2
Direct LHC bounds on colored SUSY particles now corner naturalness more than the measured value of the Higgs mass does. Bounds on the gluino are of particular importance, since it…
Supersymmetry in the shadow of photini
Masha Baryakhtar, Nathaniel Craig, Ken Van Tilburg
Additional neutral gauge fermions -- "photini" -- arise in string compactifications as superpartners of U(1) gauge fields. Unlike their vector counterparts, the photini can acquire…
Identifying Boosted Objects with N-subjettiness
Jesse Thaler, Ken Van Tilburg
We introduce a new jet shape -- N-subjettiness -- designed to identify boosted hadronically-decaying objects like electroweak bosons and top quarks. Combined with a jet invariant m…
