As more types of mesons were discovered in accelerator experiments later, it was eventually found that the mu meson significantly differed not only from the pi meson (of about the same mass), but also from all other types of mesons.
Later, the discovery of the pi meson showed it to have the properties of Yukawa's particle.
Newer mesons also showed evidence of behaving like the pi meson in nuclear interactions, but not like the mu meson.
