The QCD Rotator

Peter Hasenfratz (Bern)

The low lying spectrum of QCD in a spatial box of size 2.5 fermi, or
larger, has a spectrum which is a quantum mechanical rotator with small
corrections. We calculated this spectrum in the chiral limit up to NNL order
in chiral perturbation theory (ChPT). Combining this result with numerical
simulations in QCD will help to improve the precision of the three low energy
constants which enter in this order.
