The coupling of the electroweak gauge bosons of the Standard Model (SM) of particle physics to leptons is flavour universal.
Experimental tests of this principle are highly sensitive to New Physics particles which couple differently among the leptonic families.
The flavour anomalies that have been observed could imply the existence of lepton-flavour violating $b$-hadron decays.
Recent results in the study of rare decays in the $b\rightarrow s/d$ sector from the ATLAS, CMS and LHCb collaborations are presented.
Measurements of the branching fraction in $B_{s}^{0}$ and $\Xi_{b}^{-}$ decays, study of the angular properties of $B^{0}$, $B^{+}$ and $B_{s}^{0}$ decays, and test of the lepton flavour universality via $B^{+}\rightarrow K^{+}l^{+}l^{-}$ processes are discussed in these proceedings.
