WebA quark combines with an antiquark to form mesons such as the pion. Quarks have never been observed, and physicists do not expect to find one. Presumably the forces between quarks are so strong that they cannot be separated from other quarks in a hadron. There are several indirect confirmations of the existence of quarks. WebIn subatomic particle: Quarks and antiquarks. The pi-meson, or pion, which is the lightest meson and an important component of cosmic rays, exists in three forms: with charge e … WebThe quark composition of the positively charged pion is. π + = u d ¯ . while the neutral pion is. π 0 = u u ¯ − d d ¯ 2. These two composite formulae are completely analogous: these pions are mesons, i.e. quark-antiquark bound states, and they just differ in which quarks from the double ( u, d) are used. download driver hp officejet 3830 series

WebIn the above, the wavy lines are virtual vector bosons. I've put two in because, as Anna V notes, the pion is a psuedoscalar and so has zero spin. Of course the heavy quarks don't appear very much in a light meson since they have to be made from borrowed energy. People aren't much interested in the heavy quark contribution to the pion.
