Triangle Nuclear Theory Colloquium

Alain Coc (Paris)

Date: Thursday, May 1, 2014 - 3:30pm

Primordial nucleosynthesis (or BBN) is one of the three observational evidences for the Big¿Bang model. It is very special as it involves only a dozen main nuclear reactions and because, contrary to stellar models, within the standard BBN model, the thermodynamic con- ditions can be calculated from first principles, that can be tested in that way.

Triangle Nuclear Theory Colloquium

Jacques Soffer (Temple U.)

Date: Tuesday, May 6, 2014 - 3:30pm

We will first recall why the nucleon spin sructure is such a difficult and subtle

problem, not yet fully understood in QCD. We will then describe the quantum statistical approach to parton distributions and some recent results, in particular related to the nucleon spin structure. Future measurements are challenging to check the validity of this novel framework.
