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 present predictions on the total cross sections and on the rho parameter for present and future pp and (-)pp colliders, and on total cross sections for gammap-->hadrons at cosmic-ray energies and for gammagamma-->hadrons up to sqrt[s]=1 TeV. These predictions are based on an extensive study of possible analytic parametrizations invoking the largest(More)
For more efficient knowledge exploration and searching for relevant information on the Internet, it is worthwhile to take the level of expertise of the authors of papers and materials into account and assess the reliability of sources. A measure is proposed to assess the level of expertise of authors, which takes the occurrence of relevant ideas and phrases(More)
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 − → hadrons) have been heightened. We report on the integrated data compilation of available data of e + e − → hadrons, transformed to a unique and meaningful style that implements(More)
Proposal to correct the PDG and NIST/CODATA tables 1. In the last edition of the Review of Particle Physics [1] there are two different values of the Fermi coupling constant. The first estimate presented in the Table 1.1 (page 77) reads as G F /(ˉ hc) (2) is presented there in the Sec. 10 " Electroweak model and constraints on new physics " (page 98). From(More)
We present predictions on the total cross sections and on the ratio of the real part to the imaginary part of the elastic amplitude (ρ parameter) for present and future pp and ¯ pp colliders, and on total cross sections for γp → hadrons at cosmic-ray energies and for γγ → hadrons up to √ s = 1 TeV. These predictions are based on an extensive study of(More)
