Mesons named with the letter "f" are scalar mesons (as opposed to a pseudo-scalar meson), and mesons named with the letter "a" are axial-vector mesons (as opposed to an ordinary vector meson) a.k.a. an isoscalar vector meson, while the letters "b" and "h" refer to axial-vector mesons with positive parity, negative C-parity, and quantum numbers I G of 1 + and 0 − respectively.
Because mesons are composed of quarks, they participate in both the weak interaction and strong interaction. Mesons with net electric charge also participate in the electromagnetic interaction. Mesons are classified according to their quark content, total angular momentum, parity and various other properties, such as C-parity and G-parity.

The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism's spin-1 photon, the source of which is the four-current, a first-order tensor). Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from ...
production of neutral pseudoscalar mesons by photons interacting with an atomic nucleus: Delbrück scattering: deflection of high-energy photons in the Coulomb field of nuclei Deep inelastic scattering: a lepton is deflected by a virtual photon emitted by a quark from the hadron Chiral anomaly
In high energy physics, a scalar meson is a meson with total spin 0 and even parity (usually noted as J P =0 +).In contrast, pseudoscalar mesons have odd parity. The first known scalar mesons have been observed since the late 1950s, with observations of numerous light states and heavier states proliferating since the 1980s.
It is part of the vector meson nonet [4] [5] and mediates the nuclear force along with pions and rho mesons. Properties. The most common decay mode for the ω meson is
