How many quarks do mesons have
WebPions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions π + and π − decaying after a mean lifetime of 26.033 nanoseconds (2.6033 × 10 −8 seconds), and the neutral pion π 0 decaying after a much shorter lifetime of 85 attoseconds (8.5 × 10 −17 seconds). Quarks have fractional electric charge values – either (−1/3) or (+2/3) times the elementary charge (e), depending on flavor. Up, charm, and top quarks (collectively referred to as up-type quarks) have a charge of +2/3 e; down, strange, and bottom quarks (down-type quarks) have a charge of −1/3 e. Antiquarks have the opposite charge to their corresponding quarks; up-type a…

Since baryons are made of three quarks, whereas mesons are made of only two (one quark and one antiquark), we would expect mesons to be lighter (on average) than baryons. This is, in fact, the case. What is surprising, perhaps, is how …

WebMesons are hadrons containing an even number of valence quarks (at least 2). [1] Most well known mesons are composed of a quark-antiquark pair, but possible tetraquarks (4 quarks) and hexaquarks (6 quarks, comprising either a dibaryon or three quark-antiquark pairs) may have been discovered and are being investigated to confirm their nature.
