LHCb

Scrutinising cosmic antimatter production with an innovative use of LHCb

“The real prize is finding something new out there” is one of the most famous citations by Vera Rubin, the scientist who around 1975 firstly observed the anomalous rotation curves of spiral galaxies, providing evidence for the possible existence of…

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…
