Description
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-6 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.
