Abstract

Because of an incorrect evaluation of Eqs. (1) and (2), the upper limits on the coupling strengths gae and a'/a of pseudoscalar and vector bosonic superweakly interacting massive particles (super-WIMPs) deduced from the GERDA data (blue curves in Fig. 3) are incorrect. The corrected constraints are shown in the new Fig. 3 below. Depending on the particle mass, the correction has worsened the limits for gae by a factor between 1.8 and 1.9, and for a'/a by a factor between 3.3 and 3.6. As to the coupling strengths quoted on page 011801-5 for the mass of 150 keV / c 2 , the limit at 90% credible interval (C.I.) increases for gae from gae (Formula Presented).
