The Circular Electron Positron Collider (CEPC) is designed as a future Higgs Factory. Like most high energy physics experiments, the offline software consists of many packages. BSM (Bundled Software Manager) is thus created in order to simplify the deployment and usage of software which has many packages and dependencies. BSM utilizes Git as the software release repository. The details of software are defined in the Git repository including installation instructions, environment, dependencies, etc. Commands are supported for various shells. Json output and python API are also available for advanced development. The installation of each package could be configured separately and extended with customized handlers. BSM manages the environment variables and the version switching is easy. It also has fine environment control on a single package. Users can also define their own packages easily and these packages will be managed by BSM with simple configuration. CEPC software has already set up the deployment procedure with BSM. And BSM is also designed with flexibility to create different applications other than CEPC software. It is suitable for the projects including a lot of packages and it is safe for different BSM applications to coexist with each other under proper configuration.

Particle identification (PID) plays a key role in heavy-flavor physics in high-energy physics experiments. However, its impact on Higgs physics is still not clear. In this note, we will explore some of the potential of PID to improve the identification of heavy-flavor jets by using identified charged kaons in addition to the traditional vertexing information. This could result in a better measurement of the Higgs-charm Yukawa coupling at the future [Formula: see text] colliders.

BEPC, which is the first high energy particle accelerator to be built in the People’s Republic of China, is being constructed in Beijing. It consists of four main subsystems: a 1.4 GeV electron-positron linac, a 2.2–2.8 GeV storage ring, a magnetic spectrometer for high energy physics experiments, and synchrotron radiation facilities. All its components are described here in detail, and the current status of the construction is reported.

The DØ experiment at Fermilab's Tevatron will record several petabytes of data over the next five years in pursuing the goals of understanding nature and searching for the origin of mass. Computing resources required to analyze these data far exceed capabilities of any one institution. Moreover, the widely scattered geographical distribution of DØ collaborators poses further serious difficulties for optimal use of human and computing resources. These difficulties will exacerbate in future high energy physics experiments, like the LHC. The computing grid has long been recognized as a solution to these problems. This technology is being made a more immediate reality to end users in DØ by developing a grid in the DØ Southern Analysis Region (DØSAR), DØSAR-Grid, using all available resources within it and a home-grown local task manager, McFarm. We will present the architecture in which the DØSAR-Grid is implemented, the use of technology and the functionality of the grid, and the experience from operating the grid in simulation, reprocessing and data analyses for a currently running HEP experiment.

ABSTRACTCerium fluoride offers a reasonable compromise between parameters like the density, the light yield, the scintillation characteristics (particularly the decay time) and the radiation hardness, and is considered today as the best candidate for large electromagnetic calorimeters in future High Energy Physics experiments. Details on the performances of large crystals produced by different manufacturers all over the world and measured by the Crystal Clear collaboration will be shown and the usefulness of a good collaboration between the industry and the users will be highlighted by some examples on the light yield and radiation hardness improvement.
