We developed an on-line intelligent argumentation system which facilitates stakeholders in exchanging dialogues. It provides decision support by capturing stakeholders’ rationale through arguments. As part of the argumentation process, stakeholders tend to both polarise their opinions and form polarisation groups. The challenging issue of assessing argumentation polarisation had not been addres...

Polarisation measurements of pulsars and of their pulsar wind nebulae (PWNe) are uniquely able to provide deep insights into the highly magnetised relativistic environment of young, rotationpowered isolated neutron stars (INSs). Besides the radio band, optical observations are primarily suited to providing such insights. The first INS for which optical polarisation observations were performed i...

We report the measurement of charged hadron production at different pseudo-rapidity values in deuteron+gold as well as proton-proton collisions at √ sNN = 200GeV at RHIC. The nuclear modification factors RdAu and Rcp are used to investigate new behaviors in the deuteron+gold system as function of rapidity and the centrality of the collisions respectively.

To explain the production of light nuclei in heavy-ion collisions at extreme energies, we focus on deuteron case. A Gibbs ensemble chemical freeze-out is a prerequisite to investigate non-equilibrium evolution expanding fireball. Quantum statistical approaches allow describe correlations including bound state formation strongly interacting and hot system. We consider virial approach evaluate pr...

We calculate the forward unpolarised doubly-virtual Compton scattering (VVCS) off deuteron in framework of pionless effective field theory, up to next-to-next-to-next-to-leading order (N3LO) for longitudinal and next-to-leading (NLO) transverse amplitude. The charge elastic form factor deuteron, obtained from residue VVCS amplitude, is used extract value single unknown two-nucleon one-photon co...

The birefringence effect in the nuclear pseudoelectric field of matter and an external electric field for a particle (deuteron, nucleus) moving in a storage ring is discussed. The influence of the birefringence effect on the EDM measurement experiments is considered. The attention is drawn to the possibility to measure the spin-dependent amplitude of the elastic coherent scattering of a deutero...

The deuteron deep inelastic unpolarized structure function F 2 is calculated using the Wilson operator product expansion method. The long distance behaviour, related to the deuteron bound state properties, is evaluated using the Bethe–Salpeter equation with one particle on–mass–shell. The calculation of the ratio F 2 D/2F 2 N is compared with other convolution models showing important deviation...
