Status of Detector Requirements for FCC-ee
No full textFor the future lepton collider FCC-ee, different detector designs are studied and optimized. They must first achieve the required performances for heavy-flavour tagging, particle identification, tracking and particle-flow reconstruction, as well as lepton, jet, missing energy and angular resolutions, needed to successfully develop the very broad FCC-ee physics program, and exploit the extremely high statistical precision offered by this future collider. On top of that, they must all satisfy the constraints imposed by the challenging interaction region layout. FCC feasibility studies are being now carried out, using benchmark physics processes to determine, via appropriate simulations, the requirements on the detector performance which can guarantee that the systematic uncertainties of the measurements will be lowered as far as possible with the tiny statistical uncertainties as the target. Additionally, the potential for discovering very weakly coupled new particles, in decays of Z or Higgs bosons, motivates dedicated detector designs that would increase the efficiency for reconstructing the unusual signatures of such processes. These studies are crucial input to the further optimization of the two concepts described in the FCC-ee Conceptual Design Report, CLD and IDEA, and to the development of new concepts which might prove to be even better suited for the FCC-ee physics program

Sustainability in the Energy System and in the Industrial System
No full textWith the term “industrial system”, one refers to the set of processes, technologies, and infrastructure used to produce goods and services in a society. This includes the factories, machinery, and all the equipment used to manufacture products, as well as the transportation and distribution systems that deliver the products to customers
The Missing top: Prospects at the Tevatron.
No full textA new run has begun at the Tevatron Collider, and two detectors, CDF and D0, have started taking data. After a short review of the situation of the top search in both the single and dilepton channel, we present the expectations for the near and far future. There have already been accelerator and detector upgrades, and more are to come. Important improvements are also expected from new analysis tools
Comments on the CDF 88-89 di-lepton top candidate event
No full textCDF reported a possible top candidate event from their 988/89 run. The event was interpreted and reconstructed as pp→tt→ W + W + jet(b) + + jet(B) + Μ.(B) by some authors. We study the structure of the event to see whether this interpretation is likely. © 1994 Società Italiana di Fisica
