Improved description of light nuclei through chiral effective field theory at leading order

I present a rearrangement of the most commonly invoked version of the two-nucleon chiral potential so that the low-lying amplitude zero of the 1S0 partial wave is subsumed at first order in the effective expansion. Adopting other partial waves from the LENPIC interaction, I show through a no-core shell model calculation how such modification yields an improved description of ground-state energies and point-proton radii of three test nuclei, namely 3H, 4He and 6He. I discuss possible implications of this proposal and point out some future research lines. This presentation is based upon the recent preprint \underline {https://arxiv.org/abs/2002.12258}
