Signatures and Detection Prospects for sub-GeV Dark Matter with Superfluid Helium
Yining You, Jordan Smolinsky, Wei Xue +4
We explore the possibility of using superfluid helium for direct detection of sub-GeV dark matter (DM). We discuss the relevant phenomenology resulting from the scattering of an in…
Superfluid Effective Field Theory for Dark Matter Direct Detection
Konstantin T. Matchev, Jordan Smolinsky, Wei Xue +1
We develop an effective field theory (EFT) framework for superfluid He to model the interactions among quasiparticles, helium atoms and probe particles. Our effective field t…
A Quantum Algorithm for Model-Independent Searches for New Physics
Konstantin T. Matchev, Prasanth Shyamsundar, Jordan Smolinsky
We propose a novel quantum technique to search for unmodeled anomalies in multidimensional binned collider data. We propose associating an Ising lattice spin site with each bin, wi…
FASER's Physics Reach for Long-Lived Particles
FASER Collaboration, Akitaka Ariga, Tomoko Ariga +25
FASER,the ForwArd Search ExpeRiment,is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in…
Self-Interacting Dark Matter With a Neutrinophilic Scalar Mediator
Arvind Rajaraman, Jordan Smolinsky
We examine the phenomenology of a simplified model of fermionic dark matter coupled to a light scalar mediator carrying lepton number 2. We find that the mediator can be very light…
FASER: ForwArd Search ExpeRiment at the LHC
Jonathan L. Feng, Iftah Galon, Felix Kling +1
New physics has traditionally been expected in the high- region at high-energy collider experiments. If new particles are light and weakly-coupled, however, this focus may be…
US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Impact of Resonance on Thermal Targets for Invisible Dark Photon Searches
Jonathan L. Feng, Jordan Smolinsky
Dark photons in the MeV to GeV mass range are important targets for experimental searches. We consider the case where dark photons decay invisibly to hidden dark matter th…
Dark Photons from Captured Inelastic Dark Matter Annihilation: Charged Particle Signatures
Jordan Smolinsky, Philip Tanedo
The dark sector may contain a dark photon that kinetically mixes with the Standard Model photon, allowing dark matter to interact weakly with normal matter. In previous work we ana…
Particle Physics Models for the 17 MeV Anomaly in Beryllium Nuclear Decays
Jonathan L. Feng, Bartosz Fornal, Iftah Galon +4
The 6.8 anomaly in excited 8Be nuclear decays via internal pair creation is fit well by a new particle interpretation. In a previous analysis, we showed that a 17 MeV protophobi…
Protophobic Fifth Force Interpretation of the Observed Anomaly in Be Nuclear Transitions
Jonathan L. Feng, Bartosz Fornal, Iftah Galon +4
Recently a 6.8 anomaly has been reported in the opening angle and invariant mass distributions of pairs produced in nuclear transitions. The data are exp…
Dark Sunshine: Detecting Dark Matter through Dark Photons from the Sun
Jonathan L. Feng, Jordan Smolinsky, Philip Tanedo
Dark matter may interact with the Standard Model through the kinetic mixing of dark photons, , with Standard Model photons. Such dark matter will accumulate in the Sun and anni…
Dark Photons from the Center of the Earth: Smoking-Gun Signals of Dark Matter
Jonathan L. Feng, Jordan Smolinsky, Philip Tanedo
Dark matter may be charged under dark electromagnetism with a dark photon that kinetically mixes with the Standard Model photon. In this framework, dark matter will collect at the…
On-Shell Mediators and Top-Charm Dark Matter Models for the Fermi-LAT Galactic Center Excess
Arvind Rajaraman, Jordan Smolinsky, Philip Tanedo
An excess in gamma-rays from the galactic center observed by the Fermi Large Area Telescope has been proposed as a possible signal of dark matter annihilation. Recently, the Fermi…
