Production of doubly heavy baryons via Higgs boson decays
We systematically analyzed the production of semi-inclusive doubly heavy
baryons (, and ) for the process through four main Higgs decay
channels within the framework of non-relativistic QCD. The contributions from
the intermediate diquark states, ,
, , , and , have been taken into consideration.
The differential distributions and three main sources of the theoretical
uncertainties have been discussed. At the High Luminosity Large Hadron
Collider, there will be about 0.43 events of ,
6.32 events of and 0.28 events of
produced per year. There are fewer events produced at the Circular Electron
Positron Collider and the International Linear Collider, about events of , events of and
events of in operation.Comment: 15 pages, 3 figures, 7 table
IDEF method-based simulation model design and development
The purpose of this study is to provide an IDEF method-based integrated
framework for a business process simulation model to reduce the model development time
by increasing the communication and knowledge reusability during a simulation project. In
this framework, simulation requirements are collected by a function modeling method
(IDEF0) and a process modeling method (IDEF3). Based on these requirements, a
common data model is constructed using the IDEF1X method. From this reusable data
model, multiple simulation models are automatically generated using a database-driven
simulation model development approach. The framework is claimed to help both
requirement collection and experimentation phases during a simulation project by
improving system knowledge, model reusability, and maintainability through the systematic
use of three descriptive IDEF methods and the features of the relational database
technologies. A complex semiconductor fabrication case study was used as a testbed to
evaluate and illustrate the concepts and the framework. Two different simulation software
products were used to develop and control the semiconductor model from the same
knowledge base. The case study empirically showed that this framework could help
improve the simulation project processes by using IDEF-based descriptive models and the
relational database technology. Authors also concluded that this framework could be easily
applied to other analytical model generation by separating the logic from the dataPeer Reviewe
