1. Novel Direct Detection Constraints on Light Dark Matter / Bringmann, Torsten ; Pospelov, Maxim
All attempts to directly detect particle dark matter (DM) scattering on nuclei suffer from the partial or total loss of sensitivity for DM masses in the GeV range or below. [...]

2. Foraging for dark matter in large volume liquid scintillator neutrino detectors with multiscatter events / Bramante, Joseph ; Broerman, Benjamin ; Kumar, Jason ; Lang, Rafael F. ; et al
We show that dark matter with a per-nucleon scattering cross section 1028 cm2 could be discovered by liquid scintillator neutrino detectors like Borexino, SNO+, and JUNO. [...]

3. Cosmological beam dump: Constraints on dark scalars mixed with the Higgs boson / Fradette, Anthony ; Pospelov, Maxim ; Pradler, Josef ; Ritz, Adam
Precision cosmology provides a sensitive probe of extremely weakly coupled states due to thermal freeze-in production, with subsequent decays impacting physics during well-tested cosmological epochs. [...]

4. Light vectors coupled to bosonic currents / Dror, Jeff A. ; Lasenby, Robert ; Pospelov, Maxim
New spin-1 particles with masses below the weak scale are present in many theories of beyond Standard Model (SM) physics. [...]

5. Millicharged Particles in Neutrino Experiments / Magill, Gabriel ; Plestid, Ryan ; Pospelov, Maxim ; Tsai, Yu-Dai
We set constraints and future sensitivity projections on millicharged particles (MCPs) based on electron scattering data in numerous neutrino experiments, starting with MiniBooNE and the Liquid Scintillator Neutrino Detector (LSND). [...]

6. Dipole portal to heavy neutral leptons / Magill, Gabriel ; Plestid, Ryan ; Pospelov, Maxim ; Tsai, Yu-Dai
We consider generic neutrino dipole portals between left-handed neutrinos, photons, and right-handed heavy neutral leptons (HNL) with Dirac masses. [...]

7. Light scalars and dark photons in Borexino and LSND experiments / Pospelov, Maxim ; Tsai, Yu-Dai
Bringing an external radioactive source close to a large underground detector can significantly advance sensitivity not only to sterile neutrinos but also to “dark” gauge bosons and scalars. [...]

8. Room for New Physics in the Rayleigh-Jeans Tail of the Cosmic Microwave Background / Pospelov, Maxim ; Pradler, Josef ; Ruderman, Joshua T. ; Urbano, Alfredo
We show that, despite stringent constraints on the shape of the main part of the cosmic microwave background (CMB) spectrum, there is considerable room for its modification within its Rayleigh-Jeans (RJ) end, ωTCMB. [...]

9. Signatures of dark radiation in neutrino and dark matter detectors / Cui, Yanou ; Pospelov, Maxim ; Pradler, Josef
We consider the generic possibility that the Universe’s energy budget includes some form of relativistic or semi-relativistic dark radiation (DR) with nongravitational interactions with standard model (SM) particles. [...]

10. Directly Detecting MeV-Scale Dark Matter Via Solar Reflection / An, Haipeng ; Pospelov, Maxim ; Pradler, Josef ; Ritz, Adam
If dark matter (DM) particles are lighter than a few MeV/c2 and can scatter off electrons, their interaction within the solar interior results in a considerable hardening of the spectrum of galactic dark matter received on Earth. [...]
