摘要

BESS-Polar, PAMELA和AMS-02报告的高精度宇宙射线低能反质子通量与主要宇宙射线与星际介质相互作用的二次产物一致。这严重限制了反质子原初起源的可能性，如超对称暗物质的湮灭或衰变或原始物质的蒸发

New result of Antideuteron search in BESS-Polar II

High precision cosmic-ray low energy antiproton ﬂuxes reported by BESS-Polar, PAMELA and AMS-02 are consistent with secondary production from interactions of primary cosmic rays with the interstellar medium. This severely constrains the possibility of antiprotons of primary origin such as annihilation or decay of supersymmetric dark matter or evaporation of primordial
