DETECTING TECHNIBARYON DARK-MATTER

The technibaryon constitutes a possible dark matter candidate. Such a particle with electroweak quantum numbers is already nearly ruled out as the dominant component of the galactic dark matter by nuclear recoi l experiments. Here, the scattering of singlet technibaryons, without electroweak quantum numbers, is considered. For scalar technibaryons t he most important interaction is the charge radius. The scattering rat es are typically of order 10(-4) (kg keV day)(-1) for a technicolor sc ale of 1 TeV. For fermionic technibaryons the most important interacti on is the magnetic dipole moment. The scattering rates in this case ar e considerably larger, typically between 10(-1) and 1 (kg keV day)(-1) , depending on the detector material. Rates this large may be detectab le in the next generation of nuclear recoil experiments. Such experime nts will also be sensitive to quite small technibaryon electric dipole moments.
