DARK MATTER CANDIDATE FROM CONFORMALITY

Abelian quiver gauge theories provide candidates for the conformality approach to physics beyond the standard model which possess novel cancellation mechanisms for quadratic divergences. A Z_2 symmetry (R parity) can be imposed and leads naturally to a dark matter candidate which is the Lightest Conformality Particle (LCP), a neutral spin-1/2 state with weak interaction annihilation cross section, mass in the 100 GeV region and relic density of non-baryonic dark matter Ω_dm which can be consistent with the observed value Ω_dm≃ 0.24.
