Makoto Kobayashi
The other half of the 2008 prize for physics was awarded to Makoto Kobayashi and Toshihide Maskawa for their 1972 work on quark mixing. The resulting quark mixing matrix is known as CKM matrix, after Nicola Cabibbo, Kobayashi, and Maskawa. Like Jona-Lasinio, Cabibbo arguably merited a share of the award.
