Query: Group-theoretical construction of finite-momentum and multi-particle
  operators for lattice hadron spectroscopy   Determining the spectrum of hadronic excitations from Monte Carlo simulations
requires the use of interpolating operators that couple to multi-particle
states. Recent algorithmic advances have made the inclusion of multi-hadron
operators in spectroscopy calculations a practical reality. In this talk, a
procedure for constructing a set of multi-hadron interpolators that project
onto the states of interest is described. To aid in the interpretation of
simulation data, operators are designed to transform irreducibly under the
lattice symmetry group. The identification of a set of optimal single-hadron
interpolators for states with non-zero momenta is an essential intermediate
step in this analysis.
