Description
We perform non-perturbative lattice studies of pseudoscalar particle scattering states and of the vector resonance state in Sp(4) gauge theory coupled to two fundamental Dirac fermions. In the context of dark matter phenomenology, the corresponding continuum theory can provide a production mechanism for strongly interacting massive particles that serve as a candidate for dark matter. We compute the finite-volume spectrum of the composite states interpolated by both vector and two-pseudoscalar operators, and employ Luscher's formula to extract the information concerning properties of the infinite-volume scattering processes in the 10-plets of the unbroken Sp(4) group, corresponding to the isospin-1 channel of two-flavour QCD. We present our preliminary findings for the cases with large, moderate, and relatively small fermion masses.
