Comment on "Probing two- and three-dimensional electrons in MgB2 with soft x-ray angle-resolved photoemission"
arXiv:1502.03226
Abstract
A recent article by Sassa et al. [Phys. Rev. B 91, 045114 (2015)] reports on a soft x-ray angle-resolved photoemission study of MgB2. The analysis and/or presentation of the collected data and the corresponding calculations appear to be partially inconsistent. The aim of this comment is to provide a guide to these inconsistencies and to discuss their influence on the presented conclusions.
