Recent highlights from the Belle and Belle II experiments / Yubo Han [BELLE2-CONF-PROC-2024-022]
22 September 2024

The Belle experiment at the KEKB factory in Tsukuba served as a B factory with the primary goal of discovering CP violation (CPV) in B meson decays and confirming the Cabibbo-Kobayashi-Maskawa (CKM) paradigm [...]
