First observation of forward $Z\to b\bar{b}$ production in $pp$ collisions at $\sqrt{s}=8$ TeV

LHCb collaboration, R. Aaij, B. Adeva +804

The decay $Z\to b\bar{b}$ is reconstructed in $pp$ collision data, corresponding to 2 fb${}^{-1}$ of integrated luminosity, collected by the LHCb experiment at a centre-of-…
