| dc.description | DISASTER++ is a C++ class library for the calculation of (1+1) and (2+1)-jet-like quantities in deeply inelastic lepton-nucleon scattering for one-photon exchange in next-to-leading-order QCD perturbation theory. The calculation is based on the subtraction formalism. The user has access to an event record such that an arbitrary set of infrared-safe observables can be calculated in a single run. Compared to other existing universal programs, the full dependence on the number of flavours and on the renormalization and factorization scales is made explicit. An interface class providing a simple interface from C++ to existing FORTRAN programs is available. In a preliminary study DISASTER++ is compared to two other programs for various bins of the lepton variables $x_B$ and $y$, where a particular emphasis is put on different behaviours for $ξ\to 1$ of the parton densities $f(ξ)$. We find good agreement of DISASTER++ and DISENT (Version 0.1). The comparison of DISASTER++ and MEPJET (Version 2.0) leads to several discrepancies. | |
| dc.description | 20 pages (Latex). Comparison with a new and corrected version of the Catani-Seymour program DISENT, and a slightly extended comparison with the Mirkes-Zeppenfeld program MEPJET. The conclusions are modified. The source code for the program can be obtained from http://wwwcn.cern.ch/~graudenz/disaster.html | |
