The pion also plays a crucial role in cosmology, by imposing an upper limit on the energies of cosmic rays surviving collisions with the cosmic microwave background , through the Greisen—Zatsepin—Kuzmin limit.

In the standard understanding of the strong force interaction as defined by quantum chromodynamics , pions are loosely portrayed as Goldstone bosons of spontaneously broken chiral symmetry.

That explains why the masses of the three kinds of pions are considerably less than that of the other mesons, such as the scalar or vector mesons.

If their current quarks were massless particles, it could make the chiral symmetry exact and thus the Goldstone theorem would dictate that all pions have a zero mass.

Empirically, since the light quarks actually have minuscule nonzero masses, the pions also have nonzero rest masses.

The pion can be thought of as one of the particles that mediate the interaction between a pair of nucleons.

This interaction is attractive: it pulls the nucleons together. Written in a non-relativistic form, it is called the Yukawa potential. The pion, being spinless, has kinematics described by the Klein—Gordon equation.

In the terms of quantum field theory , the effective field theory Lagrangian describing the pion-nucleon interaction is called the Yukawa interaction.

With the addition of the strange quark , one can say that the pions participate in an SU 3 flavour symmetry, belonging to the adjoint representation 8 of SU 3.

The other members of this octet are the four kaons and the eta meson. Pions are pseudoscalars under a parity transformation. Pion currents thus couple to the axial vector current and pions participate in the chiral anomaly.

Pions, which are mesons with zero spin , are composed of first- generation quarks. The two combinations have identical quantum numbers , and hence they are only found in superpositions.

Together, the pions form a triplet of isospin. They decay due to the weak interaction. The primary decay mode of a pion, with a branching fraction of 0.

The second most common decay mode of a pion, with a branching fraction of 0. This "electronic mode" was discovered at CERN in [6]. The suppression of the electronic decay mode with respect to the muonic one is given approximately up to a few percent effect of the radiative corrections by the ratio of the half-widths of the pion—electron and the pion—muon decay reactions,.

Its mechanism is as follows: The negative pion has spin zero; therefore the lepton and the antineutrino must be emitted with opposite spins and opposite linear momenta to preserve net zero spin and conserve linear momentum.

However, because the weak interaction is sensitive only to the left chirality component of fields, the antineutrino has always left chirality , which means it is right-handed, since for massless anti-particles the helicity is opposite to the chirality.

This implies that the lepton must be emitted with spin in the direction of its linear momentum i. If, however, leptons were massless, they would only interact with the pion in the left-handed form because for massless particles helicity is the same as chirality and this decay mode would be prohibited.

Therefore, suppression of the electron decay channel comes from the fact that the electron's mass is much smaller than the muon's. The electron is relatively massless compared with the muon, and thus the electronic mode is greatly suppressed relative to the muonic one, virtually prohibited.

Although this explanation suggests that parity violation is causing the helicity suppression, the fundamental reason lies in the vector-nature of the interaction which dictates a different handedness for the neutrino and the charged lepton.

Thus, even a parity conserving interaction would yield the same suppression. Measurements of the above ratio have been considered for decades to be a test of lepton universality.

Experimentally, this ratio is 1. Beyond the purely leptonic decays of pions, some structure-dependent radiative leptonic decays that is, decay to the usual leptons plus a gamma ray have also been observed.

The rate at which pions decay is a prominent quantity in many sub-fields of particle physics, such as chiral perturbation theory. No other decay modes have been established experimentally.
