Description
A long standing tension between measurements of the CKM matrix element $V_{\rm ub}$ in inclusive and exclusive decays can be eased by introducing a small right-handed weak current.
By measuring the differential decay rate of the semileptonic decay $B^{+}\rightarrow\rho^{0} \mu^{+} \nu_{\mu}$, using data from the LHCb experiment, a bound on a possible right-handed weak current can be set. This talk will focus on the first steps of the analysis where a new signal-reconstruction approach has been studied. The development and performance of a multivariate algorithm used to separate signal and background will also be presented, and finally, the status and future steps of the analysis will be discussed.
