Quarcum imum

Quarcum imum, vel quarcum b,^[1] etiam quarcum pulchritudinis appellatum, cum quarco summo, est quarcum grave et pars tertiae materiei aetatis, cuius onus electricum est −1/3 e.^?

Nonnulla hadrona quarca ima continent.

• Mesona B quarcum imum (aut eius antiparticulam) et quarcum sursum aut deorsum continent.
• Mesona B miratum et B mirum quarcum imum cum quarco lepore aut quarco miro proprie continent.
• Sunt multi status bottomonia dicti, exempli gratia particulae meson upsilon et χ_b(3P), prima particula in Large Hadron Collider inventa; quae particula in quarco imo et eius antiparticula consistunt.
• Baryona ima observata sunt, et nomina per analogiam cum baryonis miris ferunt, exempli gratia particula lambda0 imum.
