Event reweighting to account for DPA
نویسنده
چکیده
This note reports about the way it is possible to reweight four-fermion (4-f) events in order to account for the O(α) radiative corrections implemented in double pole approximation (DPA). The recommended choice for the DELPHI users is described and commented. This work is based on the new codes implementing DPA developed in the frame of the 2000 LEP2 Montecarlo workshop.

Fast Task Reweighting in Fair-scheduled Multiprocessor Systems∗
We consider the problem of task reweighting in fair-scheduled multiprocessor systems wherein each task’s processor share is specified using a weight . When a task is reweighted, a new weight is computed for it that is then used in future scheduling. Task reweighting can be used as a means for consuming (or making available) spare processing capacity. The responsiveness of a reweighting scheme c...
متن کاملReweighting of the form factors in exclusive B → X l ν l decays
A form factor reweighting technique has been elaborated to permit relatively easy comparisons between different form factor models applied to exclusive B → Xℓν ℓ decays. The software tool developped for this purpose is described. It can be used with any event generator, three of which were used in this work: ISGW2, PHSP and FLATQ2, a new powerful generator. The software tool allows an easy and ...
متن کاملModelling Bose – Einstein correlations at LEP 2 Leif
We present new algorithms for simulating Bose–Einstein correlations among final-state bosons in an event generator. The algorithms are all based on introducing Bose–Einstein correlations as a shift of final-state momenta among identical bosons, and differ only in the way energy and momentum conservation is ensured. The benefits and shortcomings of this approach, that may be viewed as a local re...

Introduction: Osteoporosis is a bone disease in which there is a reduction in the amount of bone mineral content leading to an increase in the risk of bone fractures. The affected individuals not only have to go through lots of pain and suffering but this disease also results in high economic costs to the society due to a large number of fractures. A timely and accurate diagnosis of this disea...
متن کاملOntology-based fuzzy event extraction agent for Chinese e-news summarization
An Ontology-based Fuzzy Event Extraction (OFEE) agent for Chinese e-news summarization is proposed in this article. The OFEE agent contains Retrieval Agent (RA), Document Processing Agent (DPA) and Fuzzy Inference Agent (FIA) to perform the event extraction for Chinese e-news summarization. First, RA automatically retrieves Internet e-news periodically, stores them into the e-news repository, a...
