Probing anomalous off-shell electroweak dipole moment of the top quark in single top quark production associated with Z or W bosons

An extension of the previous studies of anomalous Wtb interaction with offshell W boson was considered in associated single top quark production with W or Z bosons. More general variant with covariant derivative Dµ W − µ b − (f L W P L + f R W P R )t for the same processes is considered in this paper.
