Light scalar mesons in QCD
Stephan Narison
I present a mini-review of the masses and couplings of the bare (unmixed) light scalar mesons : from QCD spectral sum rules (…
Two-photon width and gluonic component of sigma/f_0(600)
G. Mennessier, S. Narison, W. Ochs
We analyse data on pi pi and gamma gamma scattering below 700 MeV within an improved analytic K-matrix model. This model is based on an effective theory with couplings between reso…
A Fresh Look into the Neutron EDM and Magnetic Susceptibility
Stephan Narison
We reexamine the estimate of the neutron Electric Dipole Moment (NEDM) from chiral and QCD spectral sum rules (QSSR) approaches. In the former, we evaluate the pion mass correction…
Glueball nature of the sigma/f_0(600) from pi-pi and gamma-gamma scatterings
G. Mennessier, S. Narison, W. Ochs
We estimate the I=0 scalar meson sigma/f_0(600) parameters from pi-pi and gamma-gamma scattering data below 700 MeV using an improved analytic K-matrix model. A fit of the hadronic…
Can one measure C-odd asymmetry in e+e- --> pi+pi-
J. Layssac, S. Narison
C-odd asymmetry can be studied from an accurate measurement of the angular distribution due to the interference between the S- and P-waves in e+e- --> pi+ pi- at order alpha^3. The…
