A High-Granularity Timing Detector for the ATLAS Phase-II Upgrade
A High-Granularity Timing Detector for the ATLAS Phase-II Upgrade A High-Granularity Timing Detector (HGTD) using Low Gain Avalanche Diodes (LGAD) silicon sensors is being constructed for the ATLAS phase-II upgrade program as a powerful way to address the challenges of the High-Luminosity LHC program [1]. The goal of the new silicon-based timing detector is to

Transforming NA62
Transforming NA62 The main goal of the NA62 experiment, located in CERNs North Area, is to precisely measure the K+→π+νν̅ branching fraction, which is highly sensitive to new physics processes. The analysis of data collected during 2016-2018 led to the most precise determination of the K+→π+νν̅ branching fraction and provides the strongest evidence so far

A new VELO for the LHCb experiment
A new VELO for the LHCb experiment The VELO is stacking up milestones as it races to complete installation before the Run 3 startup. The previous VErtex LOcator (VELO) is being completely replaced during Long Shutdown 2 as part of a major upgrade programme to allow the experiment to operate at an instantaneous luminosity of

Demonstrating the capabilities of a new GEM
Demonstrating the capabilities of a new GEM During the LHC Long Shutdown 2 (2019-2021), many subsystems of the CMS experiment are being upgraded including its muon system. This is located on the outer part of the experiment and consists of various types of gaseous chambers. The muon system should identify and precisely measure high momentum

A busy time at the ALICE Control Room as preparations gear up for 2022
A busy time at the ALICE Control Room as preparations gear up for 2022 After three years of challenging and intense upgrade activities and installation campaigns of LHC Long Shutdown 2 [1], ALICE started global commissioning in July to embark on a new data-taking period. Upgraded detectors and their new readouts were integrated into the

Proton beams recorded at CMS pave the way for next LHC run
Proton beams recorded at CMS pave the way for next LHC run The Long Shutdown 2 (LS2) is almost over and CERN, along with the experiments at the Large Hadron Collider (LHC), is preparing to welcome the Run 3 next year. As part of the preparation for Run 3, during the last two weeks of

The LHC pilot beam at LHCb in preparation for Run 3 start
The LHC pilot beam at LHCb in preparation for Run 3 start During the second long shutdown of the LHC, the LHCb experiment is undergoing a full metamorphosis to be able to collect an unprecedented data sample starting from next year [1]. This upgrade of LHCb has been designed to be able to operate at

The 3D printed Detector (3DET) Project
The 3D printed Detector (3DET) Project Plastic scintillator is one of the most used active materials in high-energy physics. The “3D printed Detectors” (3DET) collaboration was formed in 2019 with the goal of investigating and developing additive manufacturing as a new production technique for future scintillator-based particle detectors. The 3DET collaboration includes research institutes and

LHCb discovers a double-charm tetraquark
LHCb discovers a double-charm tetraquark Conventional mesons and baryons consist of a quark-antiquark and three quarks respectively. However, particles with an alternative quark content, known as exotic states, have been actively discussed since the birth of the constituent quark model in 1964. This discussion has been recently revived by observations of numerous tetraquark and pentaquark

Departed giants of theoretical physics
Departed giants of theoretical physics July 23rd 2021 was a sad day for the world of theoretical physics, which witnessed the passing of three giants of the field: Steven Weinberg, Toshihide Maskawa and Miguel Virasoro. Weinberg and Maskawa were awarded Nobel Prizes for their contributions to the Standard Model of particle physics, while Virasoro was
