  • A bstractWe consider the probability for a colour-singlet $ q\overline{q} $ pair to emit a gluon, in strongly and smoothly ordered antenna showers. We expand to second order in αs and compare to the second-order QCD matrix elements for Z → 3 jets, neglecting terms suppressed by $ {1 \left/ {{N_C^2}} \right.} $. We give a prescription that corrects the shower to the matrix-element result at this order for both soft and hard emissions, thereby explicitly reducing its dependence on evolution- and… CONTINUE READING
