Λ[subscript b] → Λℓ[superscript +]ℓ[superscript −] form Factors, Differential Branching Fraction, and Angular Observables from Lattice QCD with Relativistic b quarks
Using (2 + 1)-flavor lattice QCD, we compute the 10 form factors describing the Λ[subscript b] → Λ matrix elements of the b → s vector, axial vector, and tensor currents. The calculation is based on gauge field ensembles generated by the RBC and UKQCD Collaborations with a domain-wall action for the...
