Towards UV-Models of Kinetic Mixing and Portal Matter VII: A Light Dark Photon in the Model

Thomas G. Rizzo

The kinetic mixing (KM) portal, by which the Standard Model (SM) photon mixes with a light dark photon arising from a new gauge group, allows for the possibility of viable…

NuSTAR bounds on radiatively decaying particles from M82

Francisco R. Candón, Damiano F. G. Fiorillo, Giuseppe Lucente +2

Axions and other putative feebly interacting particles (FIPs) with a mass of tens to several hundreds of keVs can be produced in stellar cores with a Lorentz boost factor $E_a/m_a\…

Determination of the Strong Coupling Constant from Inclusive Semi-leptonic Meson Decays

Yuzhi Che, Long Chen, Jinfei Wu +5

We demonstrate the feasibility of determining the strong coupling constant, , from the inclusive semileptonic decay width of mesons. We express the semileptonic decay…

Search for Dark Matter Induced Airglow in Planetary Atmospheres

Carlos Blanco, Rebecca K. Leane, Marianne Moore +1

We point out that dark matter can illuminate planetary skies via ultraviolet airglow. Dark matter annihilation products can excite molecular hydrogen, which then deexcites to produ…

Observation of quantum effects on radiation reaction in strong fields

Eva E. Los, Elias Gerstmayr, Christopher Arran +28

Radiation reaction, the force experienced by an accelerated charge due to radiation emission, has long been the subject of extensive theoretical and experimental research. Experime…

Dark Matter Raining on DUNE and Other Large Volume Detectors

Javier F. Acevedo, Joshua Berger, Peter B. Denton

Direct detection is a powerful means of searching for particle physics evidence of dark matter (DM) heavier than about a GeV with volume, low-threshold detect…

Thermodynamics of Continuous Spin photons

Philip Schuster, Gowri Sundaresan, Natalia Toro

Special relativity allows massless particles to have states of different integer (or half-integer) helicities that mix under boosts, much like the spin-states of a massive particle…

Supernova electron-neutrino interactions with xenon in the nEXO detector

nEXO Collaboration, S. Hedges, S. Al Kharusi +144

Electron-neutrino charged-current interactions with xenon nuclei were modeled in the nEXO neutrinoless double- decay detector (~5 metric ton, 90% Xe, 10% Xe)…

Masked Particle Modeling on Sets: Towards Self-Supervised High Energy Physics Foundation Models

Tobias Golling, Lukas Heinrich, Michael Kagan +4

We propose masked particle modeling (MPM) as a self-supervised method for learning generic, transferable, and reusable representations on unordered sets of inputs for use in high e…
