Hadronic B_(s) decays

The study of b-hadrons made possible a great number of benchmark results in flavour physics. In recent years a lot of effort in understanding their dynamics has been done. These studies can represent a possible avenue for the discovery of physics beyond the Standard Model (SM) in less studied sectors, and can as well be used as a tool to properly test the hadronic calculations reliability. In this sense, a unique opportunity is represented by the $B_{s}$ mesons. They are less studied and known with respect to $B^{+}$ and $B^{0}$ mesons, but high precision measurement are possible with the current available statistics at b-factories and at hadronic machines. Here we present a brief collection of recent $B_{s}$ mesons results.
