Hadronic Part of the Muon g-2 Estimated on the sigma_tot^2003(e+ e- --> hadrons) Evaluated Data Compilation
V. V. Ezhela, S. B. Lugovsky, O. V. Zenin
A comprehensive as of November 2003 and evaluated data compilation on sigma_tot(e+ e- --> hadrons) was used to estimate the lowest order hadronic contribution to the muon anomalous…
Overview of the COMPETE Program
V. V. Ezhela, J. R. Cudell, P. Gauron +15
Nowadays, scientific databases have become the bread-and-butter of particle physicists. These databases must be maintained and checked repeatedly to insure the accuracy of their co…
Forward observables at RHIC, the Tevatron run II and the LHC
J. R. Cudell, V. V. Ezhela, P. Gauron +7
We present predictions on the total cross sections and on the ratio of the real part to the imaginary part of the elastic amplitude (rho parameter) for present and future pp and pb…
Analytic Amplitudes for Hadronic Forward Scattering : COMPETE Update
B. Nicolescu, J. R. Cudell, V. V. Ezhela +7
We consider several classes of analytic parametrizations of hadronic scattering amplitudes, and compare their predictions to all available forward data in hadron-hadron, gamma-p an…
Benchmarks for the Forward Observables at RHIC, the Tevatron-run II and the LHC
J. R. Cudell, V. V. Ezhela, P. Gauron +7
We present predictions on the total cross sections and on the ratio of the real part to the imaginary part of the elastic amplitude (rho parameter) for present and future pp and pb…
Total Cross Sections of e+ e- --> hadrons and pQCD Tests
K. Kang, V. V. Ezhela, S. K. Kang +3
In the light of recent muon (g-2) result by the E821 experiment at BNL, the importance of and interest in the total hadronic cross sections in e+ e- collisions and R(e+ e- --> hadr…
Analytic Amplitude Models for Forward Scattering
K. Kang, J. R. Cudell, V. V. Ezhela +5
We report on fits of a large class of analytic amplitude models for forward scattering against the comprehensive data for all available reactions. To differentiate the goodness of…
Analytic parametrizations of the non-perturbative Pomeron and QCD-inspired models
B. Nicolescu, J. R. Cudell, V. V. Ezhela +5
We consider several classes of analytic parametrizations of hadronic scattering amplitudes, and compare their predictions to all available forward data (proton- proton, antiproton-…
New measures of the quality and of the reliability of fits applied to forward hadronic data at t=0
J. R. Cudell, K. Kang, V. V. Ezhela +5
We develop five new statistical measures of the quality of fits, which we combine with the usual confidence level to determine the models which fit best all available data for tota…
A compilation of total cross section data on e^+ e^- --> hadrons and pQCD tests
O. V. Zenin, V. V. Ezhela, S. B. Lugovsky +3
All available data on the total cross sections and R-ratio of e^+ e^- --> hadrons are compiled from the PPDS(DataGuide), PPDS(ReacData) and HEPDATA(Reaction) databases and transfor…
Hadronic scattering amplitudes: medium-energy constraints on asymptotic behaviour
J. R. Cudell, V. Ezhela, P. Gauron +5
We consider several classes of analytic parametrisations of hadronic scattering amplitudes, and compare their predictions to all available forward data (p p, pbar p, pi p, K p, gam…
High-Energy Forward Scattering and the Pomeron: Simple Pole versus Unitarized Models
J. R. Cudell, V. Ezhela, K. Kang +2
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…
Soft Pomeron and Lower-Trajectory Intercepts
J. R. Cudell, V. V. Ezhela, K. Kang +2
We present a preliminary report on the determination of the intercepts and couplings of the soft pomeron and of the rho/omega and f/a trajectories from the largest data set availab…
