Charting the Fifth Force Landscape / Banks, Hannah ; McCullough, Matthew
Fifth forces arising from hidden sector scalar operator exchange, as probed in a variety of present and planned experiments, can be captured by a general dispersion relation involving one real, positive, spectral density function. [...]

Optimizing large-scale structure data analysis with the theoretical error likelihood / Chudaykin, Anton ; Ivanov, Mikhail M. ; Simonović, Marko
An important aspect of large-scale structure data analysis is the presence of non-negligible theoretical uncertainties, which become increasingly important on small scales. [...]
