The shadow of dark matter as a shadow of string theory
Abstract We point out that string theory can solve the conundrum to explain the emergence of an electroweak dipole moment from electroweak singlets through induction of those dipole moments through a Kalb–Ramond dipole coupling. This can generate a $$U_Y(1)$$ UY(1) portal to dark matter and entails...

| description | Abstract We point out that string theory can solve the conundrum to explain the emergence of an electroweak dipole moment from electroweak singlets through induction of those dipole moments through a Kalb–Ramond dipole coupling. This can generate a $$U_Y(1)$$ UY(1) portal to dark matter and entails the possibility that the $$U_Y(1)$$ UY(1) gauge field is related to a fundamental vector field for open string interactions. The requirement to explain the observed dark matter abundance relates the coupling scale M in the corresponding low-energy effective $$U_Y(1)$$ UY(1) portal to the dark matter mass $$m_\chi $$ mχ . The corresponding electron recoil cross sections for a single dipole coupled dark matter species are generically below the current limits from XENON, SuperCDMS and SENSEI, except in the GeV mass range if the electric dipole coupling becomes stronger than the magnetic coupling, $$a_e^2\ge a_m^2$$ ae2≥am2 . Furthermore, the recoil cross sections are above the neutrino floor, and the $$U_Y(1)$$ UY(1) portal can be tested with longer exposure or larger detectors. Discovery of electroweak dipole dark matter would therefore open an interesting window into string phenomenology. |
