Hadron bosons include exchange particles {meson}| for nuclear force.
properties
Mesons have masses between one-seventh proton mass and four times proton mass. Mesons have charge -1, 0, or +1. Mesons have spin 0 or 1. Mesons have lifetime from 10^-23 to 10^-8 seconds.
examples
More than 20 mesons include pi meson (pion), K meson (kaon), and eta meson. Rho meson, phi meson, and omega meson are vector mesons with negative intrinsic parity.
quarks
Mesons have quark and antiquark. Pion has up or down quark. Kaon has strange quark. Upsilon particle meson has top quark.
Psi particle or J particle meson {charmonium} has charmed quark.
Mesons {pion}| can have masses one-seventh proton mass. Pion has up quark and down antiquark, so charge is -2/3 + -1/3 = -1, and color and complementary color add to white.
charm quark-antiquark pairs {psi particle}.
