  Triggered by experimental prospects to measure electromagnetic dipole moments
of baryons containing a bottom quark, we calculate the CP-odd electric dipole
moments (EDMs) of spin-1/2 single-bottom baryons. We consider CP-violating
dimension-six operators in the Standard Model Effective Field Theory that
involve bottom quarks, and apply heavy-baryon chiral perturbation theory to
compute the EDMs of several baryons. We discuss the expected size of the EDMs
for beyond-the-Standard Model physics appearing at the TeV scale.
