| dc.description.abstractEn | We explore the effects on nuclear bulk properties of using regularization cutoffs larger than the nucleon mass within the chiral effective field theory using a power counting that ensures order-by-order renormalization in the two-nucleon system. To do so we calculate ground-state properties of the $^{16}$O nucleus in the Hartree--Fock approach in a basis made up of plane waves confined in a cube. We find a strong sensitivity to the regularization cutoff through the counter-terms in attractive singular partial waves and to the correction for spurious deeply bound states. This questions the possibility of testing in nuclei the renormalization-group invariance of renormalizable potentials from chiral effective field theory at leading order. A possible way out of this problem is proposed. | |
