NEUTRALINO PAIR PRODUCTION IN POLARIZED LEPTON-ANTILEPTON COLLISIONS

 

S.K. ABDULLAYEV, M.Sh. GOJAYEV, A.K. GULAYEVA

The process of producing a neutralino pair in arbitrarily polarized lepton-antilepton (electron-positron or muon-antimuon) collisions has been studied within the Minimal Supersymmetric Standard Model:ℓ¯+ℓ⁺→χ⁰i+χ⁰j . We consider s-channel diagrams with neutral Z-boson and Higgs-boson H ( ℎ or A ) exchanges, and t-channel diagrams with scalar ℓ¯L and ℓ⁺R t-lepton exchanges. General expressions for the differential and integral cross sections of the process are obtained, transverse and longitudinal spin asymmetries due to lepton-antilepton pair polarizations, and degrees of longitudinal and transverse neutralino polarization are determined. Angular and energy dependences of cross sections and polarization characteristics of the process are studied in detail.
