Query: Next-to-leading order calculation of three-jet observables in
  hadron-hadron collision   The production of the three jets in hadron-hardon collision is the first more
complex process which allow us to define a branch of variables in order to do
more precise measurement of the strong coupling and the parton distribution
function of the proton. This process is also suitable for studying the
geometrical properties of the hadronic final state at hadron colliders. This
requires next-to-leading order prediction of the three-jet observables. In this
paper we describe the theoretical formalism of such a calculation with
sufficient details. We use a the dipole method to construct Monte Carlo program
for calculating three-jet observables at next-to-leading order accuracy. We
present a theoretical prediction for inclusive and exclusive cross section and
for some relevant event shape variables like transverse thrust, transverse jet
broadening and Et3 variable.
