In 2017,China's Dark Matter Particle Explorer publish the results of e from 2.5GeV-4.6 TeV that there is a pronounced peak value in 1.5TeV,this abundance particle is 0.3kpc smaller than others nearby may give evidence of dark matter.Normally,cross section of dark matter annihilation through s-wave would suppresses.Nevertheless,our research illustrate that induce sommerfeld enhancement factor would enhance the suppressed cross section to an experimental detectable value,and only take slight deviation compere to ancient universe annihilation.Due to the limit of experimental measurement,we select the smaller coupling to avoid the boundary value.This research focus on the result of “DAMPE”,devise new model to the 1.5 TeV,and give theoretical derivation to the sommerfeld factor construction through the new method of enhance suppressed cross section.Meanwhile,validate the matched model,parameter limit range and results of experimental data through Micromega 4.2.Dark matter is accounted for as high as 76% in the universe mystery,for dark matter detection experiment,only the indirect detection experiment of secondary particles of dark matter has some evidence,I during the period of master for the detection of dark matter and the nature of the related study,in this article put forward a new way of thinking to explain the "DAMPE" 1.5 TeV beyond.As a framework of the standard model of particle theory,it still can't avoid some problems,such as can't really come to four mechanics,not found in the standard model of particle spectrum and the possibility of dark matter,etc.In the vortex of these problems,new physics emerges,which builds a series of new effective models,such as supersymmetry and Technicolor,through the expansion of the standard model.These models give a more natural explanation for the above problems.This article is based on the standard model and its development,dark matter detection on the basis of the study and the nature of the system,in view of the "DAMPE" the results of the 1.5 TeV beyond explanation,this paper proposes a new theory through an enhanced factor-the sommerfeld factor(Sommerfied factor)to enhance the annihilation of the s wave down section,until the annihilation section values accord with the experimental data.
