This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around world to discuss exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter gravitational waves. primary objective was lay groundwork an international TVLBAI proto-collaboration. collaboration aims unite researchers different institutions strategize...
Fifth forces arising from hidden sector scalar operator exchange, as probed in a variety of present and planned experiments, can be captured by general dispersion relation involving one real, positive, spectral density function. Previously considered fifth forces, tree-level to more exotic loop-level possibilities, are derived this formalism, without explicitly performing conventional loop calculations. A experimental observables commonly used force searches also presented the same allowing...
Canonical neutrino oscillations arise due to the propagation of three mass eigenstates from production detection. We aspire capture, in one simple framework, a broad range new physics effects on beyond this canonical picture - can be done by promoting propagators general K\"all\'en-Lehmann form. In work we demonstrate how models predicting additional light propagating species are naturally accommodated language and propose model spectrum composed just `broadened' states as flexible ansatz...
Long-baseline atom interferometers offer an exciting opportunity to explore midband gravitational waves with frequencies of 1 mHz--10 Hz. In this work we survey the landscape possible contributions total wave background from merging binary systems in frequency band and advocate for targeting observable. Such approach is complimentary searches resolved mergers individual sources may have much reveal about Universe. We highlight that inspiral phases known stellar-mass compact binaries...
Asymmetric dark matter (ADM) that is captured in stars can act as an efficient conductor of heat. Small ADM-induced changes a star's temperature gradient are known to alter neutrino fluxes and asteroseismological signatures, erase convective cores modify main sequence lifetime. The Sun's proximity us makes it ideal laboratory for studying these effects. However, the two formalisms commonly used parametrize such heat transport were developed over 30 years ago, calibrated with single set...
A bstract Significant evidence exists for the apparent disappearance of electron-type neutrinos in radioactive source experiments. Yet, interpreted within standard ‘3+1 sterile neutrino scenario’, precision short-baseline measurements electron antineutrinos from nuclear reactors strongly disagree with these results. Recently, it has been demonstrated that allowing a finite wavepacket size reactor can ameliorate such tension, however smallness required wavepackets is subject intense debate....

Dark matter captured in stars can act as an additional heat transport mechanism, modifying fusion rates and asteroseismoloigcal observables. Calculations of rely on approximate solutions to the Boltzmann equation, which have never been verified realistic stars. Here, we simulate Sun, Earth, a brown dwarf model, using radial temperature, density, composition gravitational potential profiles. We show that formalism developed arXiv:2111.06895 remains accurate across all celestial objects...
