Scalar mesons in QCD and tests of the gluon content of the sigma

Stephan Narison

We summarize the different features of the scalar mesons from QCD spectral sum rule analyses of the two- and three-point functions. The results do not favour the u-bar u + d-bar d…

UV and IR divergences within Dimensional Regularization in Non-Commutative theories and Phenomenological Implications

Stephan Narison

Using Dimensional Regularization (DR) for some two-point functions of a prototype Non-Comutative (NC) ϕ^4 scalar theory in 4-dimensions, we explictly analyze, to one-loop, the IR a…

B^0_{d,s} - \bar{B}^0_{d,s} mass-differences from QCD spectral sum rules

Kaoru Hagiwara, Stephan Narison, Daisuke Nomura

We present the first QCD spectral sum rules analysis of the SU(3) breaking parameter ξand an improved estimate of the renormalization group invariant (RGI) bag constant \hat{B}_{B_…

Light and heavy quark masses, Flavour breaking of chiral condensates, Meson weak leptonic decay constants in QCD

Stephan Narison

We review the present status for the determinations of the light and heavy quark masses, the light quark chiral condensate and the decay constants of light and heavy-light (pseudo)…
