This workshop aims at discussing latest experimental and theoretical results concerning correlations between hard and soft particles produces in high energetic hadronic collisions. 

This workshop is supported by working group of the GDR QCD : "Simple and multiple interactions within partons in nucleus". 

 It follows previous workshops: "Meeting de lancement GDR QCD - interactions simples et multiples entre partons dans les nucléons": https://indico.in2p3.fr/event/13459/  and "Partons and Nuclei" https://indico.in2p3.fr/event/14438/.

Ample time is devoted to discussion among participants.

Registration is free of charge, lunches and coffee breaks are supported by the GDR QCD, the Laboratoire de Physique de Clermont (LPC), The Université Clermont Auvergne (UCA) and the Clermont-Ferrand city.
