Experimental overview on small collision systems at the LHC

Abstract

These conferences proceedings summarize the experimental findings obtained in small collision systems at the LHC, as presented in the special session on "QGP in small systems?" at the Quark Matter 2015 conference. (The arXiv version is significantly longer than the printed proceedings, with more details and a short discussion.)
