Description

We investigate the behavior of the nuclear force as a function of the light-quark masses mq in the framework of chiral effective field theory at next-to-leading order. The unknown mq-dependent short-range contribution is estimated by means of dimensional analysis. We calculate various observables for different values of mq. We found no new bound states and a larger deuteron binding energy, BDCL = 9.6±1.9+1.8-1.0 MeV, in the chiral limit. (orig.)
