A theoretical <particle physicist> who proposed an early <grand unified theory> mechanism for <baryogenesis>. His 1978 paper asks whether reactions violating <baryon number> in the early universe could account for the excess of matter over <antimatter>. It connects a measurable cosmic asymmetry to particle reactions at much higher <energies> than laboratory experiments can directly reach.<Unified Gauge Theories and the Baryon Number of the Universe by Motohiko Yoshimura>[Abstract: baryon-number-violating early-universe reactions; source record includes 1979 erratum]{ref}
