At low energy, the weak interaction between nucleons in this approach is parameterized by the weak pion coupling constant [f.sub.[pi]], and six other meson
coupling denoted as [h.sub.[rho].sup.0], [h.sub.[rho].sup.1], [h'.sub.[rho].sup.1], [h.sub.[rho].sup.2], [h.sub.[omega].sup.0], and [h.sub.[omega].sup.1], where the subscript denotes the exchange meson
and the superscript indicates the isospin change.

measured by LHCb have hinted at an answer to why the Universe is made overwhelmingly of matter rather than antimatter, which is the next target for the team, said Prof Parkes.
The observable mass distributions of baryons, mesons
, leptons and gauge bosons are connected by the model scaling exponent 2/3.

* if n = 2, we have: qa (biquark--for example the mesons
At low energies these processes are best described by an effective meson
theory [2,3], where light virtual mesons
such as the pion, rho, or omega are exchanged between nucleons.
The [B.sub.c] meson
is the ground state of a family of mesons
containing two different heavy flavor quarks, b and c.
, which have both antimatter and matter packed inside them, were thought to have been common just after the Big Bang theorized to have created our universe, but are now thought not to occur in nature.
Key words: deuterium; gamma polarimeter; neutron polarization; weak meson
Nevertheless, we can attempt to apply the quark model to heavy-light mesons
. The outcome of this attempt is not directly using of Heavy Quark Symmetry (HQS), but one aspect of it.
