Electroweak Physics in the forward region and b$\overline b$ resonances search at the LHCb experiment

The LHCb experiment offers a complementary phase space region with respect to ATLAS and CMS to study electroweak processes, thanks to the unique acceptance and the large bandwidth trigger at low energy threshold. Here, the latest measurements performed during the LHC Run-I data taking are presented, setting the scene for the future. Possible developments in this sector are discussed, in particular the search for b$\overline b$ resonances, considered preferred channels in the observation of new exotic states and New Physics.
