Comment on the Parameters of the 3-3 Resonance

We exhibit a simple 3-parameter formula for the phase shift of the 3-3 pion-nucleon resonance which yields a mass parameter $M=1243\mathrm{}$ MeV, and a width parameter $\Gamma =152\mathrm{}$ MeV, values considerably higher than previously obtained. However, the position of the pole of the amplitude is $E_{\mathrm{pole}}=1211-51i$ MeV, a value close to that found by Ball, Campbell, Lee, and Shaw. Our result lends support to their conclusion that $E_{\mathrm{pole}}$ is the relevant quantity, rather than the parameters entering a phenomenological formula for the 3-3 phase shift.
