extension of the large-- partial wave dispersion relations
Continuing our previous work(JHEP 0706:030,2007), large-- techniques and
partial wave dispersion relations are used to discuss scattering
amplitudes. We get a set of predictions for low-energy chiral
perturbation theory couplings. They are provided in terms of the masses and
decay widths of scalar and vector mesons.Comment: 7 page

Search for electroweak production of single top quarks in collisions.
We present a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use ~90 pb^-1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with the DZero detector between 1992 and 1995. We use events that include a tagging muon, implying the presence of a b jet, to set an upper limit at the 95% confidence level on the cross section for the s-channel process ppbar->tb+X of 39 pb. The upper limit for the t-channel process ppbar->tqb+X is 58 pb. (arXiv
