Qhia pib siv Belle
Belle kev sim yog ib qho ntawm ob qhov loj tshaj plaws B-meson factories hauv ntiaj teb. Nws yog thoob ntiaj teb kev sib koom tes npaj, siv cov khoom siv hluav taws xob tshawb nrhiav high-zog Nyij Pooj' s KEKB accelerator kawm txog CP symmetry rhuav tshem. Lub npe Belle tau tshwm sim los ntawm Tswb Tshawb vim qhov kev kawm ntawm qhov kev sim no xav tau kev tsim ntau ntawm B mesons, thiab qhov chaw ntawm cov khoom lag luam tau tsim los ntawm kev sib tsoo ntawm cov hluav taws xob thiab positrons (electron iav antiparticles, el).
