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

      Alexandrou, Constantia; Gregory, E. B.; Korzec, T.; Koutsou, Giannis; Negele, J. W.; Sato, T.; Tsapalis, Antonios (2013)
      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 ...

      Structure of S/emph> from nuclear production experiments 

      Alexandrou, Constantia; Sato, T. (1987)
      The three models for the structure of S*, where it is considered as a member of the qq L=1 nonet, or as a member of the lightest q2q 2 nonet or as a KK molecule, can be distinguished by studying the A dependence of the ...

      Δ(1232) axial charge and form factors from lattice QCD 

      Alexandrou, Constantia; Gregory, E. B.; Korzec, T.; Koutsou, Giannis; Negele, J. W.; Sato, T.; Tsapalis, Antonios (2011)
      We present the first calculation on the Δ axial vector and pseudoscalar form factors using lattice QCD. Two Goldberger-Treiman relations are derived and examined. A combined chiral fit is performed to the nucleon axial ...
