Using the largest data set available, we determine the best values that the data at t = 0 (total cross sections and real parts of the hadronic amplitudes) give for the intercepts and couplings of the soft pomeron and of the ρ/ω and a/f trajectories. We show that these data cannot discriminate between a simple-pole fit and asymptotic log 2 s and log s fits,(More)
We present a preliminary report on the determination of the intercepts and couplings of the soft pomeron and of the ρ/ω and f /a trajectories from the largest data set available for all total cross sections and real parts of the hadronic amplitudes. 8 Factorization is reasonably satisfied by the pomeron couplings, which allows us to make predictions on γγ(More)
We describe a general Godunov-type splitting for numerical simulations of the Fisher-Kolmogorov-Petrovski-Piskunov growth and diffusion equation on a world map with Neumann boundary conditions. The procedure is semi-implicit, hence quite stable. Our principal application for this solver is modeling human population dispersal over geographical maps with(More)
