37. Hadronic Physics in Geant4: Improvements and Status for LHC Start

Prof. Vladimir Ivantchenko (CERN, ESA)

3. Computation in Theoretical Physics

Parallel Talk

An overview of recent developments for the Geant4 hadronic modeling is provided with a focus on the start of the LHC experiments. Improvements in Pre-Compound model, Binary and Bertini cascades, models of elastic scattering, quark-gluon string and Fritiof high energy models, and low-energy neutron transport were introduced using validation versus data from thin target experiments. Many of...

0. Two approaches to Combining Significances

3. Computation in Theoretical Physics

Parallel Talk

We compare two approaches to the combining of signal significances: the approach, in which the signal significances are considered as corresponding random variables, and the approach with the using of confidence distributions. Several signal significances, which are often used in analysis of data in experimental physics as a measure of excess of the observed or expected number of...

31. Radiative corrections to Drell-Yan like processes in SANC

3. Computation in Theoretical Physics

Parallel Talk

Radiative corrections to processes of single Z and W boson production are obtained within the SANC computer system. Interplay of one-loop QCD and electroweak corrections is studied. Higher order QED final state radiation is taken into account. Monte Carlo event generators at the hadronic level are constructed. Matching with general purpose programs like HERWIG and PYTHIA is performed to...
