Quark mass dependence of the one-loop three-gluon vertex in arbitrary dimension

“…The results for the scalar functions of arguments (p 2 1 , p 2 2 , 0) can be obtained from the general expressions (18)- (23). In fact, the results (18)- (20) do not depend on p 2 3 . Therefore, their form is not changed.…”

“…Perturbative corrections to gluonic vertices are very important in real physical calculations, such as multijet production at the hadron colliders (see e.g. [2] and references therein). At the present high level of accuracy, one needs to perform not only calculations with on-shell external particles, there are also contributions where general off-shell results are needed.…”

Measurement of neutral mesons inp+pcollisions ats=200 GeVand scaling properties of hadron production

“…At high p T the spectra display a power law behavior that becomes more and more evident as the interaction energy increases. In this regime, the spectra are well described by perturbative QCD together with measured proton structure functions [20]. At low p T , typically p T < 2 GeV/c, a region which accounts for the bulk of the produced particles, the spectra are governed by processes that belong to the nonperturbative regime of QCD and are not yet fully understood.…”

Deep Inelastic Scattering of Leptons and Hadrons in the QCD Parton Model and Experimental Tests

“…The enormous quantity of high statistics experimental data which is now available, allows us to make rather precise tests of the QCD parton model and this theoretical picture is nowdays established on very serious basis. Deep inelastic phenomena is only one of the several areas of high energy particle physics which are the testing grounds of perturbative QCD and obviously, it has to be supplemented at least by electron-positron annihilation and hard hadronhadron collisions [63].…”
