Description
The more diffusive skin of neutrons in Pb-208 has a wide range of implications ranging from nuclear structure to heavy ion collisions to neutron stars. In this talk I will present the first determination from relativistic heavy ion collisions at the LHC, which is complementary to dedicated studies such as by the PREX collaboration at JLab. In particular I will show that the larger size of the Pb nucleus due to the skin characteristically changes the number, average momenta and angular distributions of outgoing particles. Using a state-of-the-art global analysis this constrains the size of the neutron skin to be 0.217$\pm$0.058 fm.
