Meson Mesons' spin
 Mesons are hadrons, which simply means that they are made of quarks. Since quarks have different fractional charges, mesons can have a charge. However, the charges of the quarks may cancel out, forming an uncharged meson. The rest of the hadron family are known as baryons, which are made of three quarks. Particles with an integer spin are called bosons, which obey Bose-Einstein Statistics. This means that more than one boson can actually be in the same point in space at the same time.
