    No full text
    Seafile is a popular open-source file sync and share solution, used by many organizations (edu and for-profit). Its features include robust and efficient file syncing, cross-platform virtual drive clients, efficient usage of server resources, and encrypted libraries. In this talk we'll present updates of Seafile in the year 2024. Notable updates: - Redesigned user interface - A new wiki module - SeaDoc, a light-weight collaborative document editor, is production read

    The hadron collider FCC-hh: Extended conceptual design report

    No full text
    This document provides a detailed account of several studies regarding the design of the FCC-hh hadron collider that have been performed in the time period between 2019 and 2021. They extend and complement the studies reported in the conceptual design report submitted to the 2019 Update of the European Strategy for Particle Physics

    Recent results in VBS and VBF measurement performed with the CMS experiment

    The study of vector boson scattering (VBS) and vector boson fusion (VBF) processes is crucial for testing the Standard Model (SM). This report focuses on two analyses: the electroweak production of opposite-sign W±W+W^{\pm}W^{-+} bosons in the Fully leptonic decay channel and the electroweak WVWV production in the semileptonic decay channel. Additionally, it briefly covers the ongoing single WW boson electroweak production analysis. The data sample analyzed corresponds to an integrated luminosity of 138 fb1^{-1} of proton-proton collisions at s\sqrt{s} = 13 TeV collected by the CMS detector. The VBS W±W+W^{\pm}W^{-+}  signal is observed with a significance of 5.6 standard deviations (5.2 expected) and a measured fiducial cross-section of 10.2 ±\pm 2.0 fb, consistent with the SM prediction of 9.1 ±\pm 0.6 fb. The VBS WVWV process shows the first evidence with a significance of 4.4 standard deviations observed (5.1 expected) and a measured fiducial cross-section of 1.9 ±\pm 0.5 fb, matching the SM prediction of 2.2 ±\pm 0.1 fb. Finally, the VBF WW analysis is expected to have a 15% uncertainty on the fiducial cross-section measurement

    Transmutation of 16^{16}O and 20^{20}Ne at the Large Hadron Collider

    No full text
    In July 2025 the Large Hadron Collider (LHC) will collide 16^{16}O16^{16}O and 20^{20}Ne20^{20}Ne isotopes in a quest to understand the physics of ultrarelativistic light ion collisions. One particular feature is that there are many smaller isotopes with the exact same charge over mass ratio that potentially can be produced and contaminate the beam composition. Using the Trajectum framework together with the GEMINI code we provide an estimate of the production cross-section and its consequences. A potential benefit could be the interesting measurement of the multiplicity and mean transverse momentum of 16^{16}O4^{4}He collisions
