LHCb observes CP violation in charm
LHCb observes CP violation in charm We live in a Universe of matter, which is a good thing but poses a problem: We know that in the Big Bang initially as much matter as antimatter was produced, and that the antimatter somehow disappeared. How this happened is one of the questions that the LHCb experiment

Trigger strategies for the LHCb experiment
Trigger strategies for the LHCb experiment The LHCb experiment has finished a very successful data taking period in Run 2, collecting an additional 6 inverse femtobarns of proton-proton collisions. A significant modification to the Reconstruction and Trigger system of LHCb was implemented during the first LHC long shutdown period that both enhanced the physics goals

LHCb plans for major upgrade during LS2
LHCb plans for major upgrade during LS2 During the previous LHC runs, the LHCb experiment collected 10 fb-1 and performed many important measurement in the heavy flavour sector. However, many crucial measurements are statistically limited, with experimental precision not directly comparable to the uncertainty of the theoretical predictions. In order to significantly increase the statistical

VeloPix, a new hybrid pixel readout ASIC for the LHCb upgrade
VeloPix, a new hybrid pixel readout ASIC for the LHCb upgrade 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. Unlike the currently operating

Heavy-ion collisions at Quark Matter 2018
Heavy-ion collisions at Quark Matter 2018 BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/heavy-ion-collisions-quark-matter-2018) CERN experiments presented their latest results from the study of lead-ion collisions at the annual Quark Matter conference, that was held this year in Venice, Italy. The programme includes a plethora of presentations on a variety of topics, spanning QCD at

New season starts for the LHC experiments
New season starts for the LHC experiments The last 2017 proton-proton collisions took place on 28 November and the LHC machine was shut down during the winter period to allow for planned technical interventions while the LHC experiments profit from this period to perform maintenance work on many sub-detectors. Four months later proton beams were

LHC experiments present results in Moriond Conference
LHC experiments present results in Moriond Conference This year saw the 53rd meeting in the series “Les Rencontres de Moriond”. ATLAS and CMS presented impressive results (see pictures) of searches for new phenomena, setting boundaries to where the new physics can still exist. These limits severely constrain models for physics beyond the Standard Model including

Searching for leptoquarks at the LHC
Searching for leptoquarks at the LHC Last month, Admir Greljo (University of Mainz) and Abdollah Mohammad (Kansas State University, US) during the Collider Cross Talk, gave a comprehensive overview of the theoretical and experimental aspects in leptoquarks searches. Leptoquarks are hypothetical particles that can turn quarks into leptons and vice versa and they can be

“Grand Unification” of data taking for the LHCb experiment
“Grand Unification” of data taking for the LHCb experiment The 2017 data taking period for LHCb ended at the end of November. Towards the end of the 2017 run at the centre-of-mass energy of 13 TeV, the LHC provided collisions at a reduced energy of 5 TeV to produce reference data for proton-lead and lead-lead
