DESCRIPTION:Accurately determining the smallest CKM matrix element\, $|V_{
 ub}|$\, remains a critical challenge of the Standard model due to the disc
 repancies between its exclusive and inclusive determinations. The decay pr
 ocess $B \\to \\rho \\ell \\bar{\\nu}$ is perfect to address this issue\, 
 particularly through lattice QCD calculations. In this talk\, I will discu
 ss our ongoing efforts in computing the vector and axial form factors for 
 $B \\to \\rho \\ell \\bar{\\nu}$\, focusing specifically on the unstable n
 ature of the $\\rho$\, which appears as an enhancement in P-wave $\\pi\\pi
 $ scattering. I will highlight the analysis approach\, outline our methodo
 logical strategies\, and present our recent results on a gauge ensemble wi
 th 2+1 flavors of dynamical clover fermions\, where the light quark mass c
 orresponds to a pion mass of 320 MeV.\n\nhttps://indico.bnl.gov/event/2803
