Rare flavour changing neutral current (FCNC) decays are good probes for beyond the Standard Model (SM) physics, particularly through the study of $b\to d\ell^+\ell^-$ transitions, which are highly suppressed in the SM. This talk will focus on the $\Lambda_b\to p\pi\mu\mu$ branching fraction analysis preformed with the LHCb detector using Run1 and Run2 data. Experimental techniques employed will be discussed including: reduction of background sources, Monte Carlo corrections, efficiency computations and preliminary results will be shown.
