What are Quarks?

Quark combination of a Proton
(charge and baryon number of p)

Quark combination of an antiproton

Quark combination of a neutron

Quark combination of an antineutron

Quark combination of Baryons in general

Quark composition of Pions and AntiPions

Composition of Pi+

Composition of Pi-
(n.b. this is effectively the antiparticle of Pi+)

Composition of Pi0

Composition of K- meson
And strangeness

Composition of K+ meson and strangeness?

Composition of K0 meson and strangeness

Composition of an anti K0 meson and strangeness

What does the weak interaction do?

When is strangeness conserved?

Can you separate Quarks to make solo quarks
