Restricting CP violation in the low-scale type-I seesaw with three right-handed neutrinos to the Dirac phase δ alone yields specific testable subregions of heavy-neutrino flavor mixings and permits low-scale leptogenesis to generate the observed baryon asymmetry even for O(10^{-5}) deviations from C

Projections indicate the FPF at FCC-hh can extend reach for light long-lived heavy neutrinos and Z' bosons in chiral U(1) models beyond existing experiments via meson decays and bremsstrahlung.
Proposes a hydrocarbon detector at SNS for order-of-magnitude better sensitivity to 10-100 MeV axion-like particles and heavy neutral leptons via e+e- decays from muon decays at rest.
Updated exclusion contours on lifetime, mass and abundance of decaying BSM relics from refined BBN modeling of hadronic and electromagnetic injections across multiple two-body channels.
PBHs must exceed 10^9 g to affect BBN observables, yielding beta upper limits from 10^{-17} to 10^{-19} for masses 10^9-10^10 g, with public code provided.
