      abstract     = {We present theoretical ground state energies and their
                      uncertainties for p-shell nuclei obtained from chiral
                      effective field theory internucleon interactions as a
                      function of chiral order, fitted to two- and three-body data
                      only. We apply a Similary Renormalization Group
                      transformation to improve the numerical convergence of the
                      many-body calculations, and discuss both the numerical
                      uncertainties arising from basis truncations and those from
                      omitted induced many-body forces, as well as chiral
                      truncation uncertainties. With complete
                      Next-to-Next-to-Leading (N2LO) order two- and three-body
                      interactions, we find significant overbinding for the ground
                      states in the upper p-shell, but using higher-order two-body
                      potentials, in combination with N2LO three-body forces, our
                      predictions agree with experiment throughout the p-shell to
                      within our combined estimated uncertainties. The
                      uncertainties due to chiral order truncation are noticeably
                      larger than the numerical uncertainties, but they are
                      expected to become comparable to the numerical uncertainties
                      at complete N3LO.},
