LHC experiments restart
The LHC restarted this summer, after a period of upgrades (LS2) and is gearing up to probe new realms of physics during a third run, which will be its most powerful yet. Run 3 of the LHC will feature higher-energy particle beams and higher collision…

Installation of the second half of the LHCb SciFi detector
The installation of the first half of the LHCb SciFi detector was already discussed in a previous EP newsletter article. The second half also proved to be rather challenging. First of all, the remaining six C-frames had to be assembled. Following…

New precise measurements of CP violation and mixing in beauty and charm decays at LHCb
In 1928, a young Paul Dirac wrote one of the most spectacular papers of modern physics when he successfully unified two distinct theories, quantum mechanics and special relativity. What arose from his equations was a prediction of a new form of…

LHCb VELO: “One down, one to go”
As the LHC marks the start of the final countdown to Run 3, the LHCb experiment is preparing to commission its new detector. The upgrade will allow the collaboration to pursue its physics programme into the High Luminosity era. LHCb aims to fully…

Flavour anomalies tracking attention
The Flavour Anomaly workshop took place in a successful hybrid format at the main Auditorium at CERN and the virtual world on 20th October. Pass sanitaire and workshop badge in hand, more than 80 participants could attend the event in person, while…

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…

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 five…

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…

Installation of the critical first half of the LHCb SciFi detector progresses
The LHCb SciFi tracker is the replacement of the Outer Tracker (based on gas straw tubes) and the Inner Tracker (Silicon microstrips) by a single detector technology (see also a previous EP newsletter article and a CERN Courier article). The…

Anomalous measurements: recent LHCb results deepen flavour puzzle
The crown jewel of particle physics, the Standard Model (SM), has withstood numerous experimental trials. However, there are still some observations it cannot explain. Examples such as dark matter and the matter-antimatter imbalance in the Universe…
