Ua ʻike ʻia nā ʻāpana subatomic hou e nā physicists Kanada

Ma Nowemapa 19, 2014 ka Large Hadron Collider Beauty Experiment (LHCb) i alakaʻi ʻia e CERN i ʻike i ʻelua mau ʻāpana subatomic hou. Ua wānana mua ʻia nā ʻāpana e ke kauka lapaʻau o ke Kulanui ʻo York ʻo Randy Lewis, a me Richard Woloshyn o TRIUMF, kahi keʻena physics particle ma Vancouver. ʻO Steven Blusk mai Syracuse University, New York haʻi iā CBC, "He kumu maikaʻi kā mākou e manaʻoʻiʻo ai aia kēlā mau ʻāpana ma laila".

ʻO nā mea i ʻike hou ʻia, i kapa ʻia ʻo Xi_b'- a me Xi_b*- , he mau ano barona hou. ʻO Baryons nā ʻāpana i hana ʻia me ʻekolu mau ʻāpana subatomika i kapa ʻia he quark. He ʻano like kēia mau ʻāpana me nā protons a me nā neutrons, ka mea i hana i ka nucleus o kahi atom. ʻO nā ʻāpana hou he ʻeono paha ka nui ma mua o ka proton. Loaʻa i kēia mau mea he b quark, ʻoi aku ke kaumaha ma mua o nā mea i loaʻa i loko o ka proton, e hoʻonui ai i kona nui. ʻO nā quark ʻelua ʻē aʻe i loaʻa i nā baryon hou he hoʻokahi d quark; nā mea i loaʻa i loko o nā neutrons a me nā protons, a hoʻokahi quark middleweight i ʻike ʻole ʻia.

Ua wānana ʻo Lewis lāua ʻo Woloshyn i ka nui a me ka hoʻohui ʻana o nā ʻāpana hou me ka hoʻohana ʻana i ka helu kamepiula e pili ana i ka quantum chromodynamics theory. Hōʻike kēia manaʻo i nā ʻāpana koʻikoʻi o ka mea, ke ʻano o ka pili ʻana o nā ʻāpana, a me nā ikaika ma waena o lākou. Hōʻike ka helu helu i hoʻohana ʻia i nā lula makemakika o ka hana ʻana o nā quark.
