نویسنده
چکیده
A new mechanism for spontaneous breaking of flavour symmetry is demonstrated. An exactly flavour symmetric model with degenerate bare nonets and with sufficiently strong tri-linear meson couplings is shown to lead to selfconsistency equations which are unstable. Instead there exists a stable solution, which break flavour symmetry spontaneously in the mass spectrum. For a C-degenerate meson spectrum the stable mass spectrum obeys the OkuboZweig-Iizuka (OZI) rule and the approximate equal spacing rule. Pacs numbers:12.39.Ki, 11.30.Hv, 11.30.Qc, 12.15.Ff

The mechanism where flavour symmetry of is broken spontaneously is demonstated for a model involving nonets of pseudoscalar and vector mesons. Degenerate bare nonets of vector pseudoscalar mesons coupling sufficiently strongly to each others lead to unstable self-consistency equations, such that the SU3f symmetric spectrum breaks down into a stable isospin symmetric mass spectrum similar to the...

In this talk, I review the possibility that CPT and Lorentz symmetry might be spontaneously broken in nature by effects originating in a theory beyond the standard model, and I discuss some existing and future experimental tests.

The problem of meson bound states with N f massive fermions in two dimensional quantum electrodynamics is discussed. We speculate about the spectrum of the lightest particles by means of the effective semiclassical description. In particular, the systems of fundamental fermions with SU (2) and SU (3) flavour symmetries broken by massive terms are investigated.

We study the large N limit in the presence of magnetic monopoles in the Yang-Mills/Higgs model in three dimensions. The physics in the limit depends strongly on the distribution of eigenvalues of the Higgs field in the vacuum, and we propose a particular, nondegenerate configuration. It minimizes the free energy at the moment of symmetry breaking. Given this, the magnetic monopoles show a wide ...
