Sudakov Resummation of Multiparton Qcd Cross Sections
We present the general expressions for the resummation, up to next-to-leading logarithmic accuracy, of Sudakov-type logarithms in processes with an arbirtrary number of hard-scattering partons. These results document the formulae used by the authors in several previous phenomenological studies. The resummation formulae presented here, which are valid for phase-space factorizable observables, de...
متن کاملCorrelations and fluctuations of matrix elements and cross sections
The fluctuations and correlations of matrix elements of cross sections are investigated in open systems that are chaotic in the classical limit. The form of the correlation functions is discussed within a statistical analysis and tested in calculations for a damped quantum kicked rotator. We briefly comment on the modifications expected for systems with slowly decaying correlations, a typical f...
متن کاملExclusive and inclusive cross sections for Compton scattering from H and He
Absolute inclusive and exclusive cross sections for ionization of H and He by Compton scattering are presented and analyzed. The exclusive cross section for ionization of one electron, leaving the second electron in the ground state, is 20% smaller for H than for He. Furthermore, the exclusive cross section for ionization with excitation to the first excited state is seven times larger for H th...
متن کاملHadron Structure from Inclusive and Exclusive Cross-Sections in ep scattering
The contribution of both inclusive and exclusive cross-section data from HERA to our knowledge of parton distribution functions is reviewed and future prospects are outlined.
متن کاملLorentz Integral Transform for Inclusive and Exclusive Cross Sections with the Lanczos Method
The Lorentz Integral Transform (LIT) method is reformulated via the Lanczos algorithm both for inclusive and exclusive reactions. The new technique is tested for the total photoabsorption cross section of 3H and 4He. Due to the rapid convergence of the algorithm one has a decrease in cpu time by two orders of magnitude, but at the same time an excellent agreement with the results of a conventio...
