LHC takes on the SMEFT challenge
LHC takes on the SMEFT challenge The quest for new physics at the LHC is entering a new phase: the experiments are designing new strategies to target potential deviations from the Standard Model (SM) predictions in a systematic way, to complement the traditional “bump hunts” and, potentially, extend their sensitivity to mass regions beyond the

LHCb experiment looks forward
LHCb experiment looks forward The LHCb detector provides unique precision coverage of the forward region at the LHC, enabling world-leading studies of flavour physics and more. The collaboration is currently installing the first major upgrade of the detector. This upgrade will allow proton collisions with an instantaneous luminosity of 2 x 1033 cm-2s-1, an increase

CERN’s new open data policy supports open science
CERN's new open data policy supports open science The four main LHC collaborations (ALICE, ATLAS, CMS and LHCb) have unanimously endorsed a new open data policy for scientific experiments at the Large Hadron Collider (LHC), which was presented to the CERN Council today. The policy commits to publicly releasing so-called level 3 scientific data, the

LHCb in the hunt of tetraquarks
LHCb in the hunt of tetraquarks In 2003, the Belle collaboration reported the observation of an unexpected new particle, showing up in the mass spectrum of J/ψ π π candidated. Its mass was somewhat close to the value expected for the yet unobserved χc1(2P) charmonium, but its width was extremely narrow and completely dominated by

LHC experiments ramp-up activities
LHC experiments ramp-up activities Around the world,research centres, laboratories and universities have closed as a response to the COVID-19 pandemic — forcing an increasing number of researchers to work from home. Researchers teleworking coordinated with colleagues who had to continue working in the lab to ensure continuation of critical activities as well as a smooth

LHCb adopts GPUs in Run 3 trigger
LHCb adopts GPUs in Run 3 trigger The LHCb experiment is currently being upgraded to continue its study of beauty and charm hadrons at a five times higher instantaneous luminosity in LHC Run 3 that is now set to start in 2022. At the increased luminosity, these hadrons are produced so abundantly that selections based

Heterogeneous computing efforts for high-energy physics experiments
Heterogeneous computing efforts for high-energy physics experiments Substantial improvements to the current experiments at the LHC are underway, and new experiments are being proposed or discussed at future energy-frontier accelerators to answer fundamental questions in particle physics. At future hadron colliders, complex silicon vertex trackers (3D and 4D) and highly granular calorimeters must operate in

You have to love the penguins
You have to love the penguins In 1977 John Ellis made a bet with a student, Melissa Franklin, “If you lose this game of darts,” Franklin said, “you have to use the word ‘penguin’ in your next paper.” John Ellis lost and as a result he coined the term Penguin decays while investigating charge-parity violation

Upgrading the LHCb trigger system
Upgrading the LHCb trigger system BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/upgrading-lhcb-trigger-system) The LHCb experiment is undergoing a significant upgrade during LS2 in order to allow it to run at a five times higher instantaneous luminosity in LHC Run 3. In order to deal with the corresponding increase in pileup per bunch crossing, most

News about the lepton universality anomalies in B decays
News about the lepton universality anomalies in B decays In the Standard Model all leptons are equal. The W and Z bosons as well as the photon couple equally to electrons (e), muons (μ) and taus (τ), a rule that is known as lepton universality. The only exception is the Higgs boson, that couples according
