TL;DR: In this article, the interference of the Coulomb scattering and the hadronic scattering was measured and the ratio of the real-to-imaginary part of the forward hadronic amplitude was determined.

TL;DR: This work has measured {rho}, the ratio of the real to the imaginary part of the {ital {bar p}p} forward elastic-scattering amplitude, at {radical}{ital s} =1.8 TeV.
Abstract: We have measured {rho}, the ratio of the real to the imaginary part of the {ital {bar p}p} forward elastic-scattering amplitude, at {radical}{ital s} =1.8 TeV. Our result, {rho}=0.140{plus minus}0.069, is compared with extrapolations from lower-energy data based on dispersion relations, and with the UA4 value at {radical}{ital s} =546 GeV.

TL;DR: In this paper, the status of hadron-hadron interactions is reviewed, with emphasis on the forward and near-forward scattering regions, and a robust fitting technique is introduced in order to clean up large data samples that are contaminated by outliers, allowing us to make much better fits to hadron−hadron scattering data over very large regions of energy.

TL;DR: In this paper, the primordial abundances of the hadronic decay modes of X were derived using the JETSET 7.4 Monte Carlo event generator, which is used to calculate the spectrum of hadrons produced by the decay of X. In order to estimate the uncertainties, the Monte Carlo simulation which includes the experimental errors of the cross sections and transfered energies.
Abstract: We study the big-bang nucleosynthesis (BBN) with the long-lived exotic particle, called X. If the lifetime of X is longer than \sim 0.1 sec, its decay may cause non-thermal nuclear reactions during or after the BBN, altering the predictions of the standard BBN scenario. We pay particular attention to its hadronic decay modes and calculate the primordial abundances of the light elements. Using the result, we derive constraints on the primordial abundance of X. Compared to the previous studies, we have improved the following points in our analysis: The JETSET 7.4 Monte Carlo event generator is used to calculate the spectrum of hadrons produced by the decay of X; The evolution of the hadronic shower is studied taking account of the details of the energy-loss processes of the nuclei in the thermal bath; We have used the most recent observational constraints on the primordial abundances of the light elements; In order to estimate the uncertainties, we have performed the Monte Carlo simulation which includes the experimental errors of the cross sections and transfered energies. We will see that the non-thermal productions of D, He3, He4 and Li6 provide stringent upper bounds on the primordial abundance of late-decaying particle, in particular when the hadronic branching ratio of X is sizable. We apply our results to the gravitino problem, and obtain upper bound on the reheating temperature after inflation.

TL;DR: In this article, a new theory of strong interactions is proposed based on the notion of parity conservation in strong couplings, which is similar to the one proposed in this paper, but with three different types of couplings: hypercharge coupling, isospin coupling, and isobarsin coupling.

TL;DR: In this article, it was shown that the meson σ and κ mesons exhibit a spectrum of (squared) masses which are proportional to the sum of orbital angular momentum and radial quantum numbers.
