Abstract
We study the behaviour of the 2d Ising model in the symmetric high
temperature phase in presence of a small magnetic perturbation. We successfully
compare the quantum field theory predictions for the shift in the mass spectrum
of the theory with a set of high precision transfer matrix results. Our results
rule out a prediction for the same quantity obtained some years ago with strong
coupling methods.
