Erratum: Refining Galactic primordial black hole evaporation constraints [Phys. Rev. D <b>110</b> , 123022 (2024)]
We correct the results obtained using the diffuse x-ray emission from Xmm-Newton, in light of new results from Ref. [1], that demonstrated that the dataset employed was misevaluated.We also update our calculation of the 511 keVemission from evaporating PBHs, which leads to slightly more conservative constraints as well.Reference [1], alongside with private communication with the authors of Ref.[2], suggest that recent bounds derived using Xmm-Newton data need to be revised.This arises from a misinterpretation regarding the solid angle of the observations with respect to the geometrical factor of a given ROI (which are 30 cocentric rings centered on the Galactic Center), this has also affected other recent dark matter (DM) indirect searches.In Ref.[2], they provide data that are normalized by the exposure-weighted average solid angle, which is orders of magnitude smaller than the geometric one.Taking for example Ring 3 (12-18), which was relevant to our work, the exposure-weighted average solid angle is 3.463 10 -5 sr, while the geometric angle is 0.156 sr, which is more than 4 orders of magnitude higher.FIG. 1.Comparison of the predicted DM-induced x-ray emission with diffuse x-ray data from Xmm-Newton in a region close to the Galactic Center.We show the prediction is shown for different values of M PBH when the PBH mass distribution is monochromatic (upper left panel), of a (upper right panel) and when the distribution is log-normal (lower panel).
