Report of the Qcd Working Group

چکیده

The activities of the QCD working group concentrated on improving the understanding and Monte Carlo simulation of multi-jet final states due to hard QCD processes at LEP, i.e. quark-antiquark plus multi-gluon and/or secondary quark production, with particular emphasis on four-jet final states and b-quark mass effects. Specific topics covered are: relevant developments in the main event generators PYTHIA, HERWIG and ARIADNE; the new multi-jet generator APACIC++; description and tuning of inclusive (all-flavour) jet rates; quark mass effects in the threeand four-jet rates; mass, higher-order and hadronization effects in four-jet angular and shape distributions; b-quark fragmentation and gluon splitting into b-quarks.

Tevatron - for - LHC Report of the QCD Working Group

The experiments at Run 2 of the Tevatron have each accumulated over 1 fb−1 of high-transverse momentum data. Such a dataset allows for the first precision (i.e. comparisons between theory and experiment at the few percent level) tests of QCD at a hadron collider. While the Large Hadron Collider has been designed as a discovery machine, basic QCD analyses will still need to be performed to under...

Data Envelopment Analysis from simulation on the Lattice QCD using CCR model

One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...

The Structure Function Working Group Summary *

In this report we summarize new results on lepton-nucleon deep inelastic scattering (DIS) from the fixed target experiments NuTeV and Hermes, and from the ep collider HERA in the range of four-momentum transfer squared, Q2, between 0.35 and 30000 GeV2. Recent next-to-leading-order (NLO) QCD fits and uncertainties of the parton distribution functions (PDFs) are discussed. In the theory part of t...

The Effects of On-the-job and Workshop Training Methods on Performance of Midwives in Report Writing

Background & aim: One of the most important professional duties of midwives is writing the reports, which considered as legal documents. Incomplete reports can resulted in misunderstanding and even lead to filing charges against midwives by the legal authorities. Therefore, this study aimed to investigate the effects of on-the-job training (OJT) and workshop training m...
