Pions, which are mesons with zero spin, are composed of first-generation quarks. In the quark model, an up quark and an anti-down quark make up a π , whereas a down quark and an anti-up quark make up the π , and these are the antiparticles of one another. The neutral pion π is a combination of an up quark with an anti-up quark or a down quark with an anti-down quark. The two combinations hav… WebWhat is the mass of the lightest vector meson formed by light quarks and antiquarks (u and d)? Please give a value in GeV accurate to within 10%.

The fact that its mass is five and one half times the mass of the pion illustrates the difficulties of assigning mass to the quarks. Hadron masses depend upon the dynamics inside the particle, and not just upon the quarks contained.
