TL;DR
This paper responds to a comment on their previous QCD-based calculation of Sigma-Lambda mixing, acknowledging discrepancies due to neglecting QED effects and suggesting future inclusion of these effects.
Contribution
The authors clarify their previous pure QCD calculation and highlight the importance of including QED effects for more accurate results.
Findings
Discrepancies arise from neglecting QED effects
Pure QCD effects considered in initial computation
Full calculations should incorporate QED effects
Abstract
In this Reply, we respond to the above Comment. Our computation [Phys. Rev. D 91 (2015) 074512] only took into account pure QCD effects, arising from quark mass differences, so it is not surprising that there are discrepancies in isospin splittings and in the Sigma - Lambda mixing angle. We expect that these discrepancies will be smaller in a full calculation incorporating QED effects.
