Special Issue Information

Dear Colleagues,

Though the standard model provides an elegant description of particle contents of the matter, it suffers from the hierarchy problem. Furthermore, the cosmological observations strongly suggest that dark matters and dark energy exist, implying new physics beyond the standard model exist. One of the best candidates for the new physics is the supersymmetry theory which can solve the hierarchy problem, maintain gauge coupling unification, and provide a suitable dark matter candidate. However,  the experimental search for supersymmetric models still remains elusive. Thus, a profound study on the phenomenology of supersymmetry theory is essential in order to discover more about new physics. Other applications of supersymmetry, such as supersymmetric quantum mechanics and mathematical studies of supersymmetry, are also encouraged in this Special Issue.

The property of dark matter remains to date unknown. However, a model-independent classification of dark matter candidates can be achieved by using various symmetries, as performed in the standard model. Fermionic dark matter has been extensively researched, and one favored candidate is the neutralino in the Minimal Supersymmetric Standard Model, which is required by fermion–boson symmetry and the preservation of R-parity. Bosonic dark matter has not been sufficiently studied, especially the scenario of dark matter with a mass of sub-GeV. In this paper, we consider the effect of spin-dependent (SD) on scalar and vector dark matter, which are mediated by pseudoscalar and axial-vector, and evaluate the effect on the dark matter–electron scattering cross-section. We list all the interactions and form factor of dark matter–electron SD scattering, and use XENON10/100/1T experiment data to derive the exclusion limit of the SD cross-section. We find that the SD scattering of scalar and vector dark matter can be three orders of magnitude stronger than spin-independent (SI) scattering due to the p-wave scattering. Full article
