We extend our investigation of heavy-light meson-meson interactions to a system consisting of a heavy-light me-son and the corresponding antiparticle. An effective potential is obtained from meson-antimeson Green-functions computed in a quenched simulation with staggered fermions. Comparisons with a simulation using an O(a 2) tree-level and tadpole improved gauge action and a full QCD simulatio...

We have investigated the ground-state properties of carbon isotopes in the framework of the relativistic mean-field (RMF) theory. RMF calculations have been performed with the non-linear scalar self-coupling of the σ meson using an axially symmetric deformed configuration. We have also introduced the vector self-coupling of the ω meson for the deformed mean-field calculations. The results show ...

In this review I classify the possible ways of CPT violation, and I describe briefly their phenomenology, in both terrestrial and astrophysical experiments, including antimatter factories, neutral mesons and neutrinos, and discuss the various sensitivities. I also pay attention to disentangling genuine quantum-gravity induced CPT violation from ‘fake’ violation due to ordinary matter effects. A...

We show that one-loop corrections with the hidden gauge boson loop preserve in the low energy limit all the successful tree level predictions of the hidden local symmetry in the SU(2)L×SU(2)R/SU(2)V chiral Lagrangian. Most amazingly, the ρ meson dominance of the pion electromagnetic form factor survives the one-loop corrections at any momentum, if and only if we take the parameter choice a = 2....

Abstract We discuss the relation between the effective vector meson mass and equation of state (EOS) for nuclear matter. In the mean field approximation, the EOS becomes softer due to the reduction of the effective ω-meson mass, if we assume that the ω-meson mean field is proportional to the baryon density. We examine the assumption by using the auxiliary field method at finite temperature and ...
