    The Belle II experiment at the SuperKEKB asymmetric e+e⁻ collider recorded data from 2019 to 2022, before entering its first long shutdown. During this period, 428 fb⁻¹ of data were collected at the Y(4S) resonance, where the cross section for B-meson pair production is highest.
    During the shutdown, the PiXel detector (PXD), which forms the inner two layers of the VerteX detector (VXD), was...

    In 2024 the Belle II experiment resumed data taking after the Long Shutdown 1, required to install a two-layer pixel detector and upgrade components of the accelerator.
    We describe the challenges of this upgrade, reporting on the operational experience.
    With new data, SVD confirmed the high hit efficiency, the large signal-to-noise and the good cluster position resolution.
    Over the next...

    The upgraded Inner Tracking System (ITS2) of the ALICE experiment at the Large Hadron Collider at CERN is based on Monolithic Active Pixel Sensors (MAPS). With a sensitive area of about 10 m^2 and 12.5 billion pixels, ITS2 represents the largest pixel detector in high-energy physics. The detector consists of seven concentric layers equipped with ALPIDE pixel sensors manufactured in the...

    The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector. Its original part consisting in 3 layers of planar pixel sensor is continuously operating since the start of LHC collisions in 2009, while its innermost layer, the Insertable B Layer (IBL) at about 3 cm from the beam line, was installed in 2014 before the start of LHC Run2 and consists of both...

    The LHCb experiment was upgraded during the Long Shutdown 2 of the LHC (2019-2021) to collect data at five times the instantaneous luminosity of Runs 1 and 2 (2 x 10^33 cm-2 s-1) using a triggerless data acquisition system. Upgrade I for the RICH system consists of new photon detectors and readout electronics together a new optical system for RICH1, with the purpose to continue to provide...

    The LHCb experiment will undergo its high luminosity detector upgrade to operate at a maximal instantaneous luminosity of 1.5 × 1034cm−2s−1. This increase poses a challenge to the tracking system to achieve proper track reconstruction with a tenfold higher occupancy. In Upgrade II, new tracking stations, called Mighty-Tracker, will replace the Scintillating Fibre (SciFi) Tracker. The...

    The CMS Muon system is undergoing a comprehensive upgrade to prepare for the High Luminosity LHC (HL-LHC), ensuring optimal performance under increased particle rates and luminosity. Key upgrades include enhancements to existing detectors and electronics, as well as the addition of new muon stations to expand coverage and improve resolution. The upgrades include enhancements to both the...

    We present a compact scintillating fiber timing detector developed for the Mu3e experiment. Mu3e is a novel experiment that will search for the charged lepton avor violating neutrinoless mu+ -> e+e-e+ decay with unprecedented sensitivity of 10^-16. In cojunction with the Si-pixel tracker, the fiber detector will allow for a full 4D track reconstruction (in space and in time).
    We will report...
