Ama-haron angavamile, noma i-physics, ayaqhubeka nokumangala
Ososayensi be-CERN baqinisekisa ukuthi ukuhlolwa kwe-Large Hadron Collider, eqanjwe kabusha ngokuthi i-Large Hadron Beauty Collider (LHCb), kuthole izinhlayiya ezintsha ezaziwa ngokuthi "ama-hadrons angaphandle". Igama labo livela eqinisweni lokuthi azikwazi ukutholwa kumodeli yendabuko ye-quark.
Ama-Hadrons ayizinhlayiya ezihilelekile ekusebenzisaneni okuqinile, njengalezo ezibophezele izibopho ngaphakathi kwe-nucleus ye-athomu. Ngokusho kwemibono esukela kuma-60s, aqukethe ama-quarks nama-antiquarks - ama-mesons, noma ama-quarks amathathu - ama-baryons. Kodwa-ke, ingxenyana etholakala ku-LHCb, ephawulwe ngokuthi Z (4430), ayihambisani nethiyori ye-quark, ngoba ingaba nama-quarks amane.
Imikhondo yokuqala yezinhlayiya ezingavamile zatholwa ngo-2008. Kodwa-ke, kusanda kwenzeka ukuthi kuqinisekiswe ukuthi i-Z(4430) iyizinhlayiyana ezinesisindo esingu-4430 MeV/c2, okuyisisindo esiphindwe kane kunesisindo seproton (938 MeV/c2). Izazi zefiziksi okwamanje azikasikiseli ukuthi kungenzeka yini ukuba khona kwama-haron angavamile.
