1. Can the Inflaton Also Be a Weakly Interacting Massive Particle? / Hooper, Dan ; Krnjaic, Gordan ; Long, Andrew J. ; McDermott, Samuel D.
We propose a class of models in which a stable inflaton is produced as a thermal relic in the early Universe and constitutes the dark matter. [...]

2. Dark matter, millicharges, axion and scalar particles, gauge bosons, and other new physics with LDMX / Berlin, Asher ; Blinov, Nikita ; Krnjaic, Gordan ; Schuster, Philip ; et al
The proposed LDMX experiment would provide roughly a meter-long region of instrumented tracking and calorimetry that acts as a beam stop for multi-GeV electrons in which each electron is tagged and its evolution measured. [...]

3. Cosmology with a very light L μ − L τ gauge boson / Escudero, Miguel ; Hooper, Dan ; Krnjaic, Gordan ; Pierre, Mathias
In this paper, we explore in detail the cosmological implications of an abelian L μ − L τ gauge extension of the Standard Model featuring a light and weakly coupled Z ′. [...]

4. Severe Constraints on New Physics Explanations of the MiniBooNE Excess / Jordan, Johnathon R. ; Kahn, Yonatan ; Krnjaic, Gordan ; Moschella, Matthew ; et al
The MiniBooNE experiment has recently reported an anomalous 4.5σ excess of electronlike events consistent with νe appearance from a νμ beam at short baseline. [...]

5. Signatures of pseudo-Dirac dark matter at high-intensity neutrino experiments / Jordan, Johnathon R. ; Kahn, Yonatan ; Krnjaic, Gordan ; Moschella, Matthew ; et al
We (re)consider the sensitivity of past (LSND) and future (JSNS2) beam dump neutrino experiments to two models of MeV-scale pseudo-Dirac dark matter. [...]

6. Freezing in, heating up, and freezing out: predictive nonthermal dark matter and low-mass direct detection / Krnjaic, Gordan
Freeze-in dark matter (DM) mediated by a light (≪ keV) weakly-coupled dark-photon is an important benchmark for the emerging low-mass direct detection program. [...]

7. M 3 : a new muon missing momentum experiment to probe ( g − 2) μ and dark matter at Fermilab / Kahn, Yonatan ; Krnjaic, Gordan ; Tran, Nhan ; Whitbeck, Andrew
New light, weakly-coupled particles are commonly invoked to address the persistent ∼ 4 σ anomaly in ( g −2) μ and serve as mediators between dark and visible matter. [...]

8. Severely Constraining Dark-Matter Interpretations of the 21-cm Anomaly / Berlin, Asher ; Hooper, Dan ; Krnjaic, Gordan ; McDermott, Samuel D.
The EDGES Collaboration has recently reported the detection of a stronger-than-expected absorption feature in the global 21-cm spectrum, centered at a frequency corresponding to a redshift of z17. [...]

9. Distorted neutrino oscillations from time varying cosmic fields / Krnjaic, Gordan ; Machado, Pedro A.N. ; Necib, Lina
Cold, ultralight (eV) bosonic fields can induce fast temporal variation in neutrino couplings, thereby distorting neutrino oscillations. [...]

10. Light weakly coupled axial forces: models, constraints, and projections / Kahn, Yonatan ; Krnjaic, Gordan ; Mishra-Sharma, Siddharth ; Tait, Tim
We investigate the landscape of constraints on MeV-GeV scale, hidden U(1) forces with nonzero axial-vector couplings to Standard Model fermions. [...]
