Erratum: Large-Nc limit reduces the number of independent few-body parity-violating low-energy constants in pionless effective field theory (Physical Review C (2016) 93 (025502) DOI: 10.1103/PhysRevC.93.025502)

© 2018 American Physical Society. There are instances of a missing sin2θW where we discuss the isotensor terms. Reference [1] is also missing this factor. The corrections are as follows: Eq. (9), (Formula Presented). scales as O (c) sin2 θ W, while Eqs. (18) and (19), (Formula Presented). contribute at O(N-1c )sin2θW. In both Eqs. (24) and (29) the lG5 term scales as (Formula Presented). while in Eq. (27) the terms A±5 scale as follows: (Formula Presented). Finally, the (Formula Presented). term in Eq. (33) scales as (Formula Presented). Our conclusions about the impact of large- Nc scaling on observables remain unchanged. While factors of sin2θW appear at the weak (matching) scale, the low-energy constants evolve in a nonperturbative (and currently undetermined) way down into hadronic scales. It is always the case that unknown multipliers can modify the naive ordering of large- Nc terms. The physics case for determining (Formula Presented). from experiment and from lattice QCD remains strong.
