Thermal Resonant Leptogenesis produces the observed baryon asymmetry via a dominant thermal channel from Higgs decays and lepton-doublet coherences, without requiring quasi-degenerate sterile neutrinos.
A decentralized Sinkhorn algorithm approximates Wasserstein barycenters using local gossip protocols, event-triggered transmissions, and b-bit quantization, with proven convergence to a neighborhood of the centralized entropic solution under mild assumptions.
DELIGHT-SHIELD uses a dedicated shield followed by tracking to suppress hadronic and electromagnetic backgrounds by up to seven orders of magnitude, reaching branching ratio sensitivity of O(10^{-9}) for h to phi phi in a dark scalar model.
ANUBIS offers the highest projected sensitivity for detecting single-photon signatures from long-lived neutralinos at the LHC among several remote detector proposals, based on six benchmark scenarios.
In a vector dark matter extension of the Higgs portal, far detectors at colliders can probe otherwise inaccessible parameter space and set novel bounds on the reheating temperature.
Tera-Z factories can produce millions of heavy neutral leptons and billions of axion-like particles under optimistic assumptions, turning them into exotics factories for discovery and detailed study.
ULYSSES v3 extends an open-source Python toolkit to numerically solve leptogenesis equations in resonant low-scale and high-scale regimes with updated interfaces and cross-checks.
STCF can reach |V_eN|^2 values one to two orders of magnitude below current bounds for heavy neutral leptons via displaced-vertex searches from ALP decays in D-meson production.
Thermal corrections to reheating and freeze-in DM production rates are generally small in the computable regime but can be large in constructed counter-examples.
Natural SUSY with axino LSP allows viable mixed axion-axino dark matter matching the observed abundance for axino masses near 100 keV and PQ scales of 10^11 to 3x10^12 GeV in DFSZ and KSVZ models.
Variations in pre-nucleosynthesis cosmology produce distinct seasons in the phase-space distribution of freeze-in dark matter, directly affecting its warmness and mass bounds.
