abstract
We estimate the maximum direct detection cross section for sub-GeV dark matter (DM) scattering off nucleons. For DM masses in the range $10 \text{ keV }- 100 \text{ MeV}$, cross sections greater than $10^{-36}$- $10^{-30} \,\text{cm}^2$ seem implausible. We present a DM candidate which realizes this maximum cross section: HighlY interactive ParticlE Relics (HYPERs). After HYPERs freeze-in, a dark sector phase transition decreases the mediator's mass. This increases the HYPER's direct detection cross section without impacting its abundance or measurements of Big Bang Nucleosynthesis and the Cosmic Microwave Background.

Dark Phoenix: dark matter relic from its own decay
A transient post-freeze-out decay window for dark matter, closed by a first-order phase transition that jumps a partner mass, can reduce an overproduced thermal relic to the observed abundance.

Inelastic Scattering Effects on Attenuation of Boosted Dark Matter
Resonant excitation of nucleons into Δ(1232) during Earth passage is a non-negligible attenuation channel for boosted dark matter at E_χ ≈ 1–2 GeV, lowering the PandaX-4T upper bound on σ̄_n in the heavy-mediator regime.

Dark matter energy exchange in stars orbiting supermassive black holes
Orbit-averaged elastic DM scattering in S4714 reaches stellar luminosity at σ_χp ∼ 10^{-36} cm² (MeV–GeV) and σ_χe ∼ 5×10^{-38} cm² (sub-MeV) for a spiked profile.

Primordial Black Hole from Tensor-induced Density Fluctuation: First-order Phase Transitions and Domain Walls
Tensor perturbations from FOPT and domain-wall sources are claimed to induce second-order scalar perturbations large enough to form primordial black holes, potentially all of the dark matter.

Direct Detection of Leptophobic Dark Matter with Electronic Collective Excitations
Leptophobic dark matter can excite plasmons in silicon through hadronic loops, and SENSEI data now constrain its nucleon cross section down to ~1e-31 cm^2 in the sub-MeV mass range.

Sub-GeV Dark Matter Under Pressure from Direct Detection
PandaX-4T S2-only data yields world-leading sub-GeV dark matter-electron scattering limits for heavy mediators in the 20-200 MeV range, although the result largely overlaps with the collaboration's own just-released analysis.
