The K2K experiment, using a fine-grained detector in a neutrino beam of energy < E > ∼ 1.3GeV has observed two-track events that can be interpreted as a coherent reaction νμ + N → μ − + N + π (N = C) or an incoherent process νμ + (p, n) → μ − + π + (p, n), the final nucleon being unobserved. The data show a significant deficit of forward-going muons in the interval Q . 0.1GeV, where a sizeable ...

The HERA collider at DESY (Hamburg) has provided Deep Inelastic Scattering (DIS) of electrons off protons in the years 1992-2007 for the H1 and ZEUS experiments with a centre of mass energy up to 318 GeV. Diffractive dissociation of photons in the reaction γ(∗) p → X p, constitute a large fraction (∼ 10%) of the visible cross section in deep inelastic scattering (DIS), and the process can be se...

We show that the neutron and proton transition densities predicted by recent quantum Monte Carlo calculations for light nuclei are consistent with pion inelastic scattering. This provides a microscopic understanding of the enhancement factors for quadrople excitations, which were needed to describe pion inelastic scattering within the nuclear shell model of Cohen and Kurath. PACS numbers: 21.60...

The present project aims to present an alternative method for the determination of the inelastic displacements using pushover analysis and directly generated inelastic spectra. The determination of the target displacement is similar to Fajfar`s N2 method, employed in Eurocode 8. Unlike the EC8, where empirical formulas are used for describing the inelastic seismic demand, the proposed method us...
