Chromoelectric Dipole Moments of Quarks in MSSM Extensions

Understand

An analysis is given of the chromoelectric dipole moment of quarks and of the neutron in an MSSM extension where the matter sector contains an extra vectorlike generation of quarks and mirror quarks.

• The analysis includes contributions to the CEDM from the exchange of the $W$ and the $Z$ bosons, from the exchange of charginos and neutralinos and the gluino.
• Their contribution to the EDM of quarks is investigated.
• The interference between the MSSM sector and the new sector with vectorlike quarks is investigated.
