Models for photon-photon total cross-sections [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2000
We present here a brief overview of recent models describing the photon-photon cross-section into hadrons. We shall show in detail results from the eikonal minijet model, with and without soft gluon summation.

Total hadronic cross sections at high energies in holographic QCD

open access: yesPhysics Letters B, 2019
We present our analysis on high energy hadron–hadron scattering in the framework of the holographic QCD. Combining the Brower–Polchinski–Strassler–Tan Pomeron exchange kernel and gravitational form factors of the involved hadrons which are obtained by ...

Illustrating Important Effects of Second-Order Sensitivities on Response Uncertainties in Reactor Physics

open access: yesJournal of Nuclear Engineering, 2021
This paper illustrates the relative importance of the largest first- and second-order sensitivities of the leakage response of an OECD/NEA reactor physics benchmark (a polyethylene-reflected plutonium sphere) to the benchmark’s underlying total cross ...

An analysis of cross sections of9Be +28Si interaction in the framework of the double folding model

open access: yesEurasian Journal of Physics and Functional Materials, 2021
In this paper the experimental data on the differential cross sections for elastic scattering of9Be ions on28Si nucleus at the energies of the incident nucleus ranging from 12 to 201.6 MeV were analyzed in the framework of the double folding model using ...

On an Expression for the Total Cross Section [PDF]

open access: yesProgress of Theoretical Physics, 1954
The well-known expression for the toral cross section inrerms of the imaginary part or'the coherent forward scattered amplitUde is. derived in a simple and general ¥fay from wave theory. 'The derivation also shows that there is a "shadow remnant" beyond the actual shadow, within· which the forward coherent scattering intensity is diminished, of ...

Holographic description of total hadronic cross sections at high energies

open access: yesEPJ Web of Conferences, 2018
We investigate the hadron-hadron total cross sections at high energies in the framework of holographic QCD. In our model setup, the involved strong interaction is described by the Brower-Polchinski-Strassler-Tan Pomeron exchange kernel, and the two form ...

Hadron-nucleon total cross section fluctuations from hadron-nucleus total cross sections [PDF]

open access: yesPhysical Review C, 1995
The extent to which information about fluctuations in hadron-nucleon total cross sections in the frozen approximation can be extracted from very high energy hadron-nucleus total cross section measurements for a range of heavy nuclei is discussed. The corrections to the predictions of Glauber theory due to these fluctuations are calculated for several ...

Total and partial photoneutron reactions cross sections – new analysis and evaluation

open access: yesEPJ Web of Conferences, 2012
The well-known problems of significant disagreements between partial photoneutron reactions (γ,n), (γ,2n) and (γ,3n) cross sections data obtained in various experiments are discussed.

Study of enhancement of total cross sections of reactions with 6He, 6,9Li nuclei

open access: yesEurasian Journal of Physics and Functional Materials, 2017
The energy dependence of total cross sections of reactions 6He + Si and 6,9Li + Si in the beam energy range 5-30 MeV/nucleon has been measured. An agreement with the published experimental data for the reaction 6He+Si was obtained. For the reaction 9Li +
