Modified Knudsen ansatz and elliptic flow in s=14 TeV pp collisions
Abstract
Assuming that hot spots are formed in initial pp collisions, in a modified Knudsen ansatz, which accounts for the entropy generation in viscous fluid evolution, we have given predictions for elliptic flow in s=14 TeV pp collisions. Predicted flow depends on the number of hot spots and hot spot sizes. If two to four hot spots of size ≈0.1 fm are formed in initial pp collisions, in events with multiplicity n mult≈10-15, modified Knudsen ansatz predicted flow is accessible experimentally in 4th order cumulant method.
