LHCb experiment

Upgrading the LHCb trigger system

by Dorothea vom Bruch (LPNHE/CNRS), Vladimir Vava Gligorov (LPNHE/CNRS) , Alex Pearce (CERN), Sascha Stahl (CERN)

In the next run of the LHC (Run 3) the upgraded LHCb experiment will operate at a factor of five times the luminosty of the first run. The LHCb trigger upgrade will enable parallel processing of 40 Tb/s: one of the biggest data challenges in HEP.

News about the lepton universality anomalies in B decays

by Patrick Koppenburgh (NIKHEF)

Several measurements from different experiments hint at a possible violation of lepton universality, yet more data hold the key to a conclusive answer.

LHCb observes CP violation in charm

by Patrick Koppenburg (Nikhef)

LHCb experiment collected an unprecedented amount of D meson decays, allowing physicists to pinpoint for the first time the tiny size of CP violation in the charm-quark sector.

Discussing the architecture and performance of the LHCb experiment trigger system that opened a wider physics potential for the LHC experiment. 

Upgrading the vertex detector of the LHCb experiment

by Wouter Hulsbergen (Nikhef) and Kazuyoshi Carvalho Akiba (Nikhef)

The new VELO will enable high precision track and vertex reconstruction to cope with the higher luminosities of Run 3.

LHCb plans for major upgrade during LS2

by Panos Charitos & Massimiliano Ferro-Luzzi

The LHCb detector will undergo a significant upgrade in parallel to the trigger system upgrade during LS2 to cope with higher luminosities and gather significantly more data.

CERN experiments present results from the study of lead-lead collisions at Quark Matter 2018.

New season starts for the LHC experiments

by Panos Charitos

Last April, the detectors of the Large Hadron Collider (LHC) witnessed their first collisions of 2017 with the machine reaching an outstanding performance. 

The LHCb-VELO group, which is composed of several institutes from the UK, Spain, Netherlands, Russia, Brazil and CERN are constructing an upgraded version of the VErtex LOcator (VELO) to be installed and commissioned during the long shutdown LS2 in 2019/2020.
