“…1 shows a similar comparison for the k t -type algorithms (we remind the reader that at NLO the jet cross section is the same for all k t -type algorithms). The exact NLO calculation was performed here with the FastJet code [27,28], which is also based on [25]. Kinematics are similar as before, except that we have used here the rapidity range |η J | ≤ 0.6.…”

“…The kinematics correspond to those used in experiments [29][30][31][32]. The exact NLO results were again obtained using the fastNLO [24] and FastJet [27,28] packages. One can see that the NJA also works very well in these cases.…”

We investigate single-inclusive high-pT jet production in longitudinally polarized pp collisions at RHIC, with particular focus on the algorithm adopted to define the jets. Following and extending earlier work in the literature, we treat the jets in the approximation that they are rather narrow, in which case analytical results for the corresponding next-to-leading order partonic cross sections can be obtained. This approximation is demonstrated to be very accurate for practically all relevant situations, even at Tevatron and LHC energies. We confront results for cross sections and spinasymmetries based on using cone-and kt-type jet algorithms. We find that jet cross sections at RHIC can differ significantly depending on the algorithm chosen, but that the spin asymmetries are rather robust. Our results are also useful for matching threshold-resummed calculations of jet cross sections to fixed-order ones.

“…The low-x behaviour of parton distributions can be considered by a triple pole pomeron model [13,14] at the initial scale Q 0 2 and then evolved using DGLAP equations. It is possible to have the same singularity structure for quarks and gluons, in agreement with Regge theory.…”

Abstract. In this paper t and x-evolutions of gluon distribution function from Dokshitzer-GribovLipatov-Altarelli-Parisi (DGLAP) evolution equation in leading order (LO) at low-x, assuming the Regge behaviour of quark and gluon at this limit, are presented. We compare our results of gluon distribution function with MRST 2001, MRST 2004 and GRV '98 parameterizations and show the compatibility of Regge behaviour of quark and gluon distribution functions with perturbative quantum chromodynamics (PQCD) at low-x. We also discuss the limitations of Taylor series expansion method used earlier to solve DGLAP evolution equations, in the Regge behaviour of distribution functions.

Die Biotechnologie begleitet den Menschen seit Jahrtausenden. Sie war lange eher unbeachtet empirisch immer weiter entwickelt worden und hat so stetig zur gesellschaftlichen Entwicklung des Menschen beigetragen. In Zeiten materieller Engpässe wurden in rasantem Tempo biotechnologische Prozesse entwickelt. Beispiele sind die Verfahren zur Herstellung von Aceton, Glycerin oder Butanol während des Ersten Weltkrieges und die Entwicklung der Antibiotika während des Zweiten Weltkrieges.
