(a) Calculate the value of the strong force coupling, a, (Q2) for Q = 10 GeV and Q = 1000 GeV, given a, (M) = 0.1185. (b) Calculate what a, (Q2) would be for Q = 10 GeV and Q = 1000 GeV if we lived in a world with three times as many quark flavours (assuming the mass of each of the 12 new quarks to be much less than 5 GeV/c²). Again, assume that as (M2) = 0.1185. (c) In this world with three times as many quarks, is QCD asymptotically free?
