Description
A long standing tension between measurements of the CKM matrix element $V_{\rm ub}$ in inclusive and exclusive semileptonic decays could be due to new physics.
By using data from the LHCb experiment, we are performing a measurement of $V_{\rm ub}$ from the decay $B^{+}\rightarrow\rho^{0} \mu^{+} \nu_{\mu}$. This talk will focus on the steps toward extracting the signal yield from data. This involves the development of a multivariate algorithm used to separate signal and background, identifying and modelling important background processes and developing a stable fit of the signal and background components. Finally the future steps and challenges of the analysis will be discussed.
