Overview of the current status for the search of electroweak bosons in CMS

With the collection of more than 150 fb−1 of data in Run I and Run II of the Large Hadron Collider, precision tests of the Standard Model (SM) are becoming increasingly possible. We present the current status of diboson searches, where the production mechanisms involve both quarkantiquark annihilation and vector boson scattering (VBS). Cross sections of diboson processes such as WW and WZ have been measured with high precision. The study of these processes is crucial in raising the sensitivity of Higgs physics where they feature as backgrounds. In addition to the inclusive cross sections, differential cross sections parametrized as a function of the transverse momentum of the bosons have been measured. For production modes through VBS, the precision of the measurements are limited by the statistics of the datasets. The search for rare SM processes such as, triboson production and double parton scattering is also presented. The discovery potential of some of these processes is augmented by the use of advanced multivariate techniques. A summary of the current status of the measurement of anomalous trilinear and quartic couplings is also presented.
