英文摘要	Recently some hints of the existence of gamma-ray line around 130 GeV are reported according to the analysis of Fermi-LAT data. If confirmed it would be the first direct evidence to show the existence of new physics beyond the standard model. Here we suggest that using the forthcoming high energy resolution gamma-ray detectors, such as CALET and DAMPE, we may test whether it is real line structure or just the background effect. For DAMPE like detector with designed energy resolution similar to 1.5%, a line significance will reach 11 sigma for the same statistics as Fermi-LAT. For about 1.4 yr survey observation, DAMPE may detect a 5 sigma signal of such a gamma-ray line. (c) 2012 Elsevier B.V. All rights reserved.
