1/N_c and 1/n preasymptotic corrections to Current-Current correlators
Jorge Mondejar, Antonio Pineda
We obtain the corrections in and in ( is the principal quantum number of the bound state) of the decay constants of scalar and pseudoscalar currents in two and f…
Constraints on Regge models from perturbation theory
Jorge Mondejar, Antonio Pineda
We study the constraints that the operator product expansion imposes on large inspired QCD models for current-current correlators. We focus on the constraints obtained by goi…
Heavy meson semileptonic decays in two dimensions in the large Nc
Jorge Mondejar
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 tran…
Extraction of the atmospheric neutrino fluxes from experimental event rate data
M. C. Gonzalez-Garcia, M. Maltoni, J. Rojo
The precise knowledge of the atmospheric neutrino fluxes is a key ingredient in the interpretation of the results from any atmospheric neutrino experiment. In the standard atmosphe…
Heavy Quark Pair Production near Threshold with Potential Non-Relativistic QCD
Antonio Pineda, Adrian Signer
We study the effect of the resummation of logarithms for t\bar{t} production near threshold and inclusive electromagnetic decays of heavy quarkonium. This analysis is complete at n…
Heavy meson semileptonic differential decay rate in two dimensions in the large Nc
Jorge Mondejar, Antonio Pineda, Joan Rojo
We study QCD in 1+1 dimensions in the large limit using light-front Hamiltonian perturbation theory in the expansion. We use this formalism to exactly compute hadroni…
