A Z4 × Z3 discrete gauge symmetry in the SM requires three new Majorana fermions whose lightest member is stable DM with mass from a singlet scalar VEV near the electroweak scale, enabling WIMP freeze-out via scalar-mediated annihilation.

abstract
We argue that an extension of the Minimal Supersymmetric Standard Model that gives rise to viable thermal inflation, and so does not suffer from a Polonyi/moduli problem, should contain right-handed neutrinos which acquire their masses due to the vacuum expectation value of the flaton that drives thermal inflation. This strongly disfavours SO(10) Grand Unified Theories. The $\mu$-term of the MSSM should also arise due to the vev of the flaton. With the extra assumption that $ m_L^2 - m_{H_u}^2 < 0 $, but of course $ m_L^2 - m_{H_u}^2 + |\mu|^2 > 0 $, we show that a complicated Affleck-Dine type of baryogenesis employing an $LH_u$ $D$-flat direction can naturally generate the baryon asymmetry of the Universe.

WIMP Dark Matter from a Natural Discrete Gauge Symmetry in the Standard Model
A Z4 × Z3 discrete gauge symmetry in the SM requires three new Majorana fermions whose lightest member is stable DM with mass from a singlet scalar VEV near the electroweak scale, enabling WIMP freeze-out via scalar-mediated annihilation.
