Description
We provide a robust calculation of hadronic decays of light vector particles ($m<2$ GeV) into an extensive set of final state configurations of mesons and baryons. We improve currently considered mesonic decay channels as included in DarkCast, and complement them by a large list of additional channels, especially in the range of excited $\rho$, $\omega$, and $\phi$ states above $m>1$ GeV. We show the effect on the branching ratios and lifetime of the vector particles and in which way this affects current limits and future sensitivities. Our results help extending experimental searches to hadronic signatures. While our calculations can be used for arbitrary vector mediator models with couplings to quarks, we focus on models that couple to baryon number as for example the $B $ model, or anomaly-free models like $B-L$ or $B-3L_i$ models. We provide the results in a python package called DeLiVeR. I will also comment on possible additional production mechanisms for vector particles.
