        "Insights from d+Au collisions on initial state and thermalization"
           /2013-as Zimányi Nehézionfizikai Téli Iskolával közös előadás/

Kivonatos ismertetés:

We have recently seen fascinating new results from p or d + nucleus collisions 
at RHIC and the LHC. High multiplicity p/d+nucleus, and even p+p collisions, 
produce particle correlations very much like those resulting from collective 
flow. Indeed, hydrodynamics is able to successfully reproduce these 
correlations. The data suggest that such systems may thermalize due to their 
large density, despite being quite small. I will summarize some of the newest 
experimental observations of hadron production and correlations in d+Au at 
RHIC.

Heavy quarks are excellent probes of the initial state structure in a nucleus 
and its interplay with final state interactions. I will review recent results 
on quarkonia, open heavy flavor, and continuum dilepton production in d+Au 
collisions at RHIC. I’ll discuss what they tell us about nuclear parton 
distributions, as well as initial and final state interactions of the heavy 
quarks.

Finally, I will describe new measurements to probe the partonic structure of 
cold nuclear matter and unravel initial from final state effects upon 
observables.
