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 s and log s fits,… (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)

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. Factorization is reasonably satisfied by the pomeron couplings, which allows us to make predictions on γγ and… (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)

is presented there in the Sec. 10 “Electroweak model and constraints on new physics” (page 98). From the caption of the Table 1.1 from [1] it follows that the majority of data placed in Table 1.1 were extracted from the NIST/CODATA database (see “CODATA Recommended Values of the Fundamental Physical constants: 1998” [2] and also NIST site). But from the… (More)

Nowadays, scientific databases have become the bread-and-butter of particle physicists. They are used not only for citation and publication [1, 2, 3, 4], but also for access to data compilations [5, 6, 7] and for the determination of the best parameters of currently accepted models [5, 6, 8]. These databases provide inestimable tools as they organize our… (More)

We consider several classes of analytic parametrizations of hadronic scattering amplitudes, and compare their predictions to all available forward data (pp, p̄p, πp,Kp, γp, γγ,Σp). Although these parametrizations are very close for √ s ≥ 9 GeV, it turns out that they differ markedly at low energy, where a universal Pomeron term ∼ ln s enables one to extend… (More)
