The Total Cross Section at the LHC: Models and Experimental Consequences
J. R. Cudell
I review the predictions of the total cross section for many models, and point out that some of them lead to the conclusion that the standard experimental analysis may lead to syst…
On the circular polarisation of light from axion-photon mixing
A. Payez, J. R. Cudell, D. Hutsemékers
From the analysis of measurements of the linear polarisation of visible light coming from quasars, the existence of large-scale coherent orientations of quasar polarisation vectors…
Axion-like particles and circular polarisation of active galactic nuclei
A. Payez, J. R. Cudell, D. Hutsemékers
The measurements of the linear polarisation of visible light from quasars give strong evidence for large-scale coherent orientations of their polarisation vectors in some regions o…
The spin-flip amplitude in the impact-parameter representation
O. V. Selyugin, J. -R. Cudell
The impact-parameter representation of the spin-flip amplitude of hadron elastic scattering is examined in different unitarisation schemes, taking the Born term of the spin-flip am…
