Standard model production of the Z (or W) boson decaying to light quarks has not been observed in a hadron collider; it was thought to be impossible. We present a new technique to observe these productions and we observe a clear W and Z peak. With the addition of Machine Learning, we apply this approach to resonances decaying to b-quarks and present, for the first time, the Z boson decaying to b-quarks in a single jet and the first measurement of gluon fusion produced Higgs bosons decaying to b-quarks. Additionally, we discuss how we can further improve this Higgs boson measurement by identifying events directly on custom FPGA based electronics as part of the CMS trigger upgrade. Finally, as a result, we present a new framework to perform Machine Learning algorithms at incredibly high speeds on FPGA processing elements.
