TL;DR: In this paper, it was shown numerically that strong deviations from Wigner's semi-circle law for the level probability density of a random matrix are obtained if the two-body nature of the hamiltonian is taken into account.

TL;DR: In this paper, the pomeron-reggeon cut converges to the weak absorption model as s → ∞, and all the reggeon cuts formed from pomerons and leading reggeons.

TL;DR: The absolute vertical muon intensity in the range 0.2 -1000 GeV/c has been determined from four different measurements as mentioned in this paper, which is 10 - 25% higher than previous spectra which have usually been normalized to the intensity at 1 GeV /c given by Rossi in 1948.

TL;DR: Weinberg's theory of purely leptonic weak interactions can be tested in neutrino-electron scattering experiments as mentioned in this paper, where cross-sections must be measured as a function of the energy of the recoil electron.

TL;DR: In this article, the decay properties of charged heavy leptons are discussed under the assumption that the conjectured neutrinos participate in the weak interactions like the known lepton.

TL;DR: In this paper, it was shown that the number of bound states of a three-body system grows according to the formula N ∼ 1/ π ln (| a |/ R ) when the ratio of scattering lengths, α, to the range, R, of two-body forces is large.

TL;DR: Using conformal invariance with the anomalous dimensions of fields, 3-point amplitude of hadronic interactions at small distances is found in a closed form in this article, where πo → 2γ (virtual) decay is forbidden.

TL;DR: In this paper, heavy-ion cross sections above the Coulomb barrier exhibit a very strong dependence on reaction kinematics, and recoil effects are essential to understand the Q dependence when one or more particles are transfered, and heavy ion transfer reactions occur preferentially at values of the kinematical variables corresponding to a classical grazing collision between soft or highly absorptive bodies.
