Axino

Ang axino ay isang hipotetikal na elementaryong partikulo na hinulaan ng ilang mga teoriya ng partikulong pisika. Ang teoriyang Peccei-Quinn ay nagtatangkang ipaliwanag ang napagmasdang phenomenon na kilala bilang malakas ng problemang CP sa pamamagitan ng pagpapakilala ng isang hipotetikal na real na skalar na partikulong tinatawag na axion. Sa pagdaragdag ng supersymmetriya sa modelo ay humuhula sa eksistensiya ng fermionikong superpartner para sa axion, ang axino at isang bosonikong superpartner na saxion. Ang lahat ng ito ay nakabigkis sa isang chiral na superfield. Ang axino ay hinulaang ang pinaka magaang na supersymmetrikong partikulo sa gayong modelo.[1] In part due to this property, it is considered a candidate for the composition of dark matter.[2]
