[en] The processes of hadroproduction of J/ Ψ on nuclei are considered in the approach of multiple scattering of intermediate leading states. It is shown that the description of experimental data available is possible when neglecting inelastic scattering and absorption cross sections of CC pair in nuclear matter. 18 refs
[en] Tensor analysing powers for inelastic deuteron scattering have been measured around 12 to 15 MeV. There is no problem to use such a tensor potential for the excited states in coupled channel calculations. However, for transition potentials, form factors are very different. A fit has been done with the first order vibrational model for 64Ni(d,d')64Ni*, 2+ at 1,344 MeV
[en] The equations of the coupled channel method for the calculations of the cross-section in the scattering of nucleus by nuclei without axial symmetry are obtained. An analysis of these equations is given. The possibility of using the data obtained from inelastic scattering to investigate the deformation character of nonaxial nuclei is evaluated. (author)
[en] An analysis of the average value of the ratio of the average product of energy and radius of particles of a family in the gamma and hadronic component of the atmospheric family is presented. The results of the calculations show the possibility of estimating experimentally the average value of Ksub(γ) for hadrons (predominantly pions) with energy above 10 TeV, of a family
[en] The cluster structure of 12C is explored and recent measurements of proton inelastic scattering, suggesting a 2+ state close to 9.6 MeV are presented. Resonant scattering studies of 10Be + 4He used to populate resonances in 14C are briefly discussed.
[en] The most recent detailed data on the unpolarized nucleon structure functions allow a precise determination of higher twist contributions. Quark-quark correlations induced by color forces are expected to be a natural explanation for such effects; indeed, a quark-diquark picture of the nucleon, previously introduced in the description of several exclusive processes at intermediate Q2 values, is found to model the proton higher twist data with great accuracy. The resulting parameters are consistent with the diquark properties suggested by other experimental and theoretical analyses. (author)
[en] In the framework of the slice transition operator technique, a general multislice theory for electron scattering in crystals is developed. To achieve this generalization, we combine the approaches for inelastic scattering derived by Yoshioka [J. Phys. Soc. Jpn. 12, 6 (1957)] and backscattering based on the formalism of Chen and Van Dyck [Ultramicroscopy 70, 29–44 (1997)]. A computational realization of the obtained equations is suggested. The proposed computational scheme is tested on elastic backscattering of electrons, where we consider single backscattering in analogy to the computational scheme proposed by Chen and Van Dyck. - Highlights: • A multislice formalism for simultaneous treatment of backscattering and inelastic scattering of electrons in crystals is presented. • A computational scheme for the proposed formalism is presented and tested on the elastic backscattering of electrons. • Suitable approximations and expansions of the operators involved are suggested.
[en] In some recent experiments (Bestwick et al 2015 Phys. Rev. Lett. 114 187201, Chang et al 2015 Nat. Mater. 14 473–7) it has been shown that in observations of the quantum anomalous Hall (QAH) effect the longitudinal resistance R L increases as temperature T increases, while Hall resistance R H loses its quantization with increase in T. This behavior was explained due to increased thermal fluctuations as T increases. We show that similar effects arise in QAH samples with quasi-helical edge modes as disorder increases in the presence or absence of inelastic scattering even at temperature T = 0. (letter)
[en] The concept of inelasticity in high energy reaction is reviewed and discussed. The derivation of inelasticity distributions in hadronic reactions is presented. Its importance in the analysis of multiparticle production processes is outlined and stressed
[en] In this paper we investigate the saturation physics in diffractive deep inelastic electron-ion scattering. We estimate the energy and nuclear dependence of the ratio sigmadiff /sigmastot. We show that saturation physics predicts that up to 37 % of the events observed at eRHIC should be diffractive. We have also studied how our results depend on the prescription to extend the saturation scale to the nuclear case. (author)
