In order to determine more accurately the energy contribution in a jet cone due to the underlying event, and in oder to understand better the ambient event environment at both the Tevatron and the LHC, a study has been carried out in CDF of the energy distribution in a cone of radius 0.7 in both jet and in minimum bias events. The results from CDF data from Run 1b have been compared with results from [Formula: see text] passed through the detector simulation program QFL.2

The response of an underwater neutrino detector is discussed for investigating its performance to the detection of muons and high energy neutrinos. The afformentioned telescope consists of an autonomous battery operated detector string to a central 4-floor tower. In this aim, we utilised a fast detector simulation program, SIRENE, to simulate the hits from Cherenkov photons at ultra high energies (as high as 1020 eV). In order to optimize the detector, analytical studies for different configurations and characteristics of the photo-multiplier tubes inside the optical modules of the telescope was also examined.

AbstractThis paper presents new sets of parameters (“tunes”) for the underlying-event model of the $${\textsc {herwig}} \,7$$ H E R W I G 7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in $${\textsc {herwig}} \,7$$ H E R W I G 7 , and are obtained from a fit to minimum-bias data collected by the CMS experiment at $$\sqrt{s}=0.9$$ s = 0.9 , 7, and $$13 \,\text {Te}\text {V} $$ 13 Te . The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the data.

Geant Simulation

The problem of absorbing CAD system defined objects into detector simulation programs like GEANT is a well known unsolved problem in HEP computing. The nature of the problem and potential approaches to a solution are discussed. A solution to one aspect of CAD to GEANT translation is presented where CAD defined objects are represented as a tree of boxes which is then absorbed into GEANT geometries. Space and time benchmarks are discussed.
