Big Bang Nucleosynthesis as a Probe of New Physics
read the original abstract
Big bang nucleosynthesis (BBN), an epoch of primordial nuclear transformations in the expanding Universe, has left an observable imprint in the abundances of light elements. Precision observations of such abundances, combined with high-accuracy predictions, provide a nontrivial test of the hot big bang and probe non-standard cosmological and particle physics scenarios. We give an overview of BBN sensitivity to different classes of new physics: new particle or field degrees of freedom, time-varying couplings, decaying or annihilating massive particles leading to non-thermal processes, and catalysis of BBN by charged relics.

Deuterium-Proton Fusion in an Effective Field Theory Constructed from On-Shell Amplitudes
A nuclear-state on-shell EFT yields S(0)=0.209±0.008 eV b for d(p,γ)3He and traces the ab initio-data offset to a natural t_E1≈−0.15 contact term.

Beyond thermal approximations: Precise cosmological bounds on Axion-Like Particles
Solving the momentum-dependent Boltzmann equation and propagating the exact non-thermal ALP spectrum into CMB analyses yields 95% limits f_a>1.63e6 GeV (e), 9.41e6 GeV (mu), 8.06e4 GeV (tau), and g_a_gamma<1.98e-8 GeV^-1.

A geometric origin for the radiative neutrino portal to secluded dark matter
A brane-separated fifth dimension gives a geometric origin for the vanishing tree-level Higgs-hidden-scalar portal, leaving seesaw neutrinos to generate a small radiative portal that makes secluded dark matter viable ...

PBH formation and Gravitational Waves as Multi-messenger Signals of First-order Phase Transitions
False-vacuum collapse during first-order phase transitions can form PBHs and emit GWs across a broad parameter range, and MeV-scale classically conformal U(1)_{B-L} symmetry breaking has the largest region where both ...
