Modified Knudsen ansatz and elliptic flow in $\sqrt{s}$=14 TeV pp collisions

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 $\sqrt{s}$=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 $\approx$0.1 fm are formed in initial pp collisions, in events with multiplicity $n_ {mult}\approx$10-15, modified Knudsen ansatz predicted flow is accessible experimentally in 4th order cumulant method.
