Next-to-leading 1/N c corrections to the upper bound on M η /M η ′ recently obtained by Georgi are considered. These corrections are just what is needed to reconcile the bound with the observed η and η ′ masses.

A numerical study of static, spherically symmetric sphaleron solutions in the standard model coupled to the dilaton field is presented. We show that sphaleron is surrounded by strong dilaton cloud which vanishes inside the sphaleron.

We study QCD in 1 + 1 dimensions in the large Nc limit using light-front Hamiltonian perturbation theory in the 1/Nc expansion. We use this formalism to exactly compute hadronic transition matrix elements for arbitrary currents at leading order in 1/Nc, which we use to write the semileptonic differential decay rate of a heavy meson and its moments. We then compare with the results obtained usin...
