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.

Mesons 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 and antimessons);
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.
B mesons, 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.
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.
Srishti will be using LHCb data, especially multi-body decays of B mesons, to search for physics beyond the Standard Model, and to understand the role of hadronic effects in rare B decays.
