Excited State Effective Masses

Presenter: George Fleming — Yale University

S. D. Cohen, G. T. Fleming, H.-W. Lin, V. Pereyra

In hep-lat/0403023, we introduced an effective mass formula for the first excited state contribution to a hadronic correlation function. We show how to derive effective mass formulae for higher excited states and how to incorporate more than one correlation function as input. In general, the effective masses will be related to the roots of a polynomial of order the number of masses desired.
