Formation Charginos and Dark matter from electron- positron annihilation

Abstract

and the cross sections for this interaction calculated by Feynman rules when 𝜸 ° is the propagator, and 𝝌 ̃𝓵 𝟎 is a leg from (𝒆 − ) or from (𝒆 + ) where 𝒊, 𝒋 = 𝟏, 𝟐, 𝒂𝒏𝒅 𝓵 = 𝟏, 𝟐, 𝟑, 𝟒. There are (128) different possible situations. The cross-sections σ (pb) calculated and graphed as a function of S (GeV) (center of mass energy) based on (MSSM), The mechanisms of Feynman diagram can be detected as:
