We consider within quantum chromodynamics the acoplanarity distribution of two hadrons produced with large transverse momenta in hadronic collisions. Our method consists of summing the leading double logarithms arising from soft-gluon bremsstrahlung, taking also into account momentum conservation. With a reasonable choice of parameters we obtain a very good agreement with the available experimental data.
