A simultaneous study of dark matter and phase transition
WebSep 3, 2024 · Scenarios for multi-component scalar dark matter based on a single Z N (N ≥ 4) symmetry are simple and well-motivated. In this paper we investigate, for the first time, the phenomenology of the Z 5 model for two-component dark matter. This model, which can be seen as an extension of the well-known singlet scalar model, features two … WebFeb 4, 2024 · [22] J. McDonald, “Gauge singlet scalars as cold dark matter,” Phys. Rev.

Pragmatic Approach to the Little Hierarchy Problem: The Case for Dark …
WebIn it is shown that it is possible to modify the standard theory by adding a scalar which possesses a discrete symmetry and to address the issue of the dark matter of the universe, within the frame work of singlet extended SM; the issue of dark matter has been studied in [6–13], while electroweak phase transition was studied in [14–23] and ... WebJun 16, 2024 · We revisit the two real singlet extension of the Standard Model with a \( {Z}_2\times {Z}_2^{\prime } \) symmetry. One of the singlet scalars S 2, by virtue of an unbroken \( {Z}_2^{\prime } \) symmetry, plays the role of a stable dark matter candidate. The other scalar S 1, with spontaneously broken Z 2-symmetry, mixes with the SM … WebFeb 24, 2024 · In the framework of U(1)XSSM, we study the Higgs mass and take the lightest CP-even sneutrino as a cold dark matter candidate. For the lightest CP-even sneutrino, the relic density and the cross section for dark matter scattering off nucleon are both researched. ... Gauge singlet scalars as cold dark matter, Phys. Rev.
