Axial vectors in DarkCast

A bstract In this work, we explore new spin-1 states with axial couplings to the standard model fermions. We develop a data-driven method estimate their hadronic decay rates based on data from ? decays and using SU(3) flavor symmetry. derive current future experimental constraints for several benchmark models. Our framework is generic can be used models arbitrary vectorial quarks. have made our calculations publicly available by incorporating them into D ark C ast package, see https://gitlab.com/darkcast/releases .
