One of the first lead-ion events recorded by ALICE in the 2011 lead-ion run

The Large Hadron Collider (LHC) has harvested a healthy crop of lead-ion collisions. In the two weeks since the beginning of the 2011 lead-ion run, some 10 times more luminosity (a measure of the number of collisions) has been delivered than in the entire 2010 lead-ion run. Analysis is in full swing for the three experiments gathering lead-ion data: ALICE, ATLAS and CMS. By studying lead-ion data, physicists probe matter as it would have been in the first instants of the Universe's life. One of the main goals is to produce tiny quantities of such matter, known as Quark Gluon Plasma, and to study how it has evolved into the kind of matter that makes up the Universe today.
