Abstract

I present preliminary results of next-generation lattice-QCD calculations of the Λ_b → p, Λ_b → Λ, and Λ_b → Λ_c form factors based on RBC/UKQCD gauge-field ensembles with 2+1 flavors of domain-wall fermions.Compared to the work published in 2015 and 2016, the new calculations include three additional ensembles (one with 139 MeV pion mass, one with 0.073 fm lattice spacing, and one with another volume) and were performed with a more accurate tuning of the charm and bottom anisotropic clover action parameters.
