Determination of the Δ(1232) axial and pseudoscalar form factors from lattice QCD

Determination of the Δ(1232) axial and pseudoscalar form factors from lattice QCD

We present a lattice QCD calculation of the Δ(1232) matrix elements of the axial-vector and pseudoscalar currents. The decomposition of these matrix elements into the appropriate Lorentz invariant form factors is carried out, and the techniques to calculate the form factors are developed and tested...
