Probing pseudo Nambu-Goldstone boson dark matter at loop level

Probing pseudo Nambu-Goldstone boson dark matter at loop level

Abstract In the standard model extended by a single complex scalar boson with a softly broken global U(1) symmetry, a pseudo Nambu-Goldstone boson becomes a candidate for dark matter. In this paper, we discuss the direct detection of the pseudo Nambu-Goldstone boson dark matter. Since the tree-level...
