| Abstract | |
Disentangling the effect of initial conditions and medium properties is an open question in the field of relativistic heavy-ion collisions. We argue that, while one can study the impact of initial inhomogeneities by varying their size, it is important to maintain the global properties fixed. We present a method to do this. We show that many observables are insensitive to the the hot spot sizes, including integrated v(n), scaled distributions of v(n), symmetric cumulants, eventplane correlations, and differential v(n)(p(T)). We find however that the factorization breaking ratio r(n) and sub-leading component in a Principal Component Analysis are more sensitive to the initial granularity and can be used to probe short-scale features of the initial density.
