Ultrarelativistically decoupling dark matter in Z' portal models has direct detection cross sections that existing experiments like LZ and XENONnT have already excluded over large regions, leaving testable space above the neutrino fog for 0.4 GeV to 1 TeV masses.

abstract
We present a comprehensive new global QCD analysis of polarized inclusive deep-inelastic scattering, including the latest high-precision data on longitudinal and transverse polarization asymmetries from Jefferson Lab and elsewhere. The analysis is performed using a new iterative Monte Carlo fitting technique which generates stable fits to polarized parton distribution functions (PDFs) with statistically rigorous uncertainties. Inclusion of the Jefferson Lab data leads to a reduction in the PDF errors for the valence and sea quarks, as well as in the gluon polarization uncertainty at $x \gtrsim 0.1$. The study also provides the first determination of the flavor-separated twist-3 PDFs and the $d_2$ moment of the nucleon within a global PDF analysis.

Simulations of 11 and 22 GeV PVDIS pseudodata indicate potential constraints on low-Q² sin²θ_W and high-x strange quark and d/u PDFs, with strong correlations requiring simultaneous QCD-electroweak analysis.
Global fit finds u and d PDFs stable to x≈0.8 with positive isospin-independent higher-twist corrections and nonzero off-shell nucleon contributions required to describe nuclear data.
The EIC Yellow Report specifies the science goals, required detector capabilities, and technology concepts needed to realize a high-luminosity electron-ion collider program.
