Oscillating scalar-field dark matter in supergravity

Seto, Osamu · Kohri, K. · Nakamura, Takashi

Original · EN

We show that an oscillating scalar field in supergravity of mass of the order of TeV with a nonzero vacuum expectation value (10¹⁰ GeV) can be a candidate of cold dark matter (CDM). To avoid the gravitino problem, we need a low reheating temperature after the primordial inflation. Then, the energy density of the oscillating scalar field satisfies all the requirements for CDM at present in the universe.
