The Cosmology of Composite Inelastic Dark Matter

JHEP 1006:113 (2010)

Works out the early-universe cosmology of composite inelastic dark matter, including the synthesis of constituent quarks into dark mesons and baryons, finding qualitatively different configurations depending on the mass hierarchy of the hidden sector.

Parity Violation in Composite Inelastic Dark Matter Models

Phys. Rev. D 82 (2010) 055023

Shows that higher-dimensional operators in composite inelastic dark matter introduce parity violation, creating an admixture of inelastic and elastic scattering channels consistent with direct detection experiments even at near-maximal parity violation.

Composite Inelastic Dark Matter

Phys. Lett. B 692 (2010) 323-326

Proposes that the DAMA annual modulation signal arises from hyperfine transitions of composite dark matter, a meson from a QCD-like hidden sector whose spin-spin interactions produce the O(100 keV) mass splitting required for inelastic scattering.
