CERN Accelerating science

Dear Colleagues, dear Members of the EP Department and CERN Users,

In this edition of the EP newsletter you will find a collection of interesting articles from all across the department. Apart from the articles giving some insights in ongoing upgrade work of the LHC experiments you will also find news from the large number of smaller experiments at CERN.


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.

Exploring the Lifetime Frontier at the LHC and Beyond

by James Beacham (ATLAS Experiment, CERN)

As searches for long-lived particles attract more attention, different exprimental approaches and novel theoretical ideas emerge to guide future searches at the LHC and beyond.


Re-discovering the Higgs boson in the Cloud

by Clemens Lange (CMS, CERN)

A collaborative effort between the ATLAS and CMS experiments with CERN's IT department enables rediscovering the Higgs boson within minutes using publicly available datasets and new computing tools.  

CMS Open data in use

by Kati Lassila-Perini (Helsinki Institute of Physics)

Following the last release of CMS open data in July and five years after the first release, through CERN's Open Data portal, it is time to reflect on the impact that these data have created.


Scientific data management with Rucio

by Martin Barisits (CERN), Mario Lassnig (CERN)

Presenting an open-source data management system for organizing, monitoring and accessing large volumes of distributed data. 


RECAST: A framework for reinterpreting physics searches at the LHC

by Lukas Heinrich (ATLAS, CERN)

The ATLAS collaboration recently published their first paper using RECAST; a novel framework for data and analysis preservation that enable future re-interpretation of collected data and broadening experimental searches for new physics. 

Finding the best candidates for atomic EDM searches

by Peter Butler & Liam Gaffney (University of Liverpool), Joonas Konki (CERN)

Using the HIE-ISOLDE accelerator, researchers concluded that radon atoms provide less favourable conditions for the enhancement of a measurable atomic EDM than radium.


Precision timing upgrade of the CMS detector

by Joel Butler (Fermilab), Keti Kaadze (Kansas State University), Tommaso Tabarelli (CERN)

A new timing detector for CMS, along with other major upgrades, will extend the detector performance and physics opportunities during the High Luminosity LHC era. 

Following six successful years of operation, the AMS-02 experiment at the ISS recently successfuly performed a major upgrade, thus extending its lifetime and giving us more data to test theories for new physics.


BASE probes antimatter - dark matter interaction

by Panagiotis Charitos

BASE experiment publishes first results from a direct search for the interacton between dark matter and antimatter, demonstrating the versatility of the experimental setup and paving the way for future measurements.

The NNLO frontier

by C. G. Papadopoulos (NCSR-Demokritos)

70 years ago, in September 1949, Richard Feynman introduced the so-called Feynman diagramms; a representation of various interactions between fundamental particles allowing the calculation of interaction probabilities. Where do we stand today with these calculations? 

Shaping the future of particle physics

by Panagiotis Charitos

The Physics Briefing Book of the 2020 EPSSU describes the main experimental goals in particle physics and proposes a bold, diverse and bright experimental programme to tackle them. 

Succesfful assembly of first prototypes of radiation hard optical links for the LHC upgrade programme paves the way for production in 2020. 

CAST: from Solar to Dark Matter Axions searches

by Marios Maroudas (University of Patras), Yannis Semertzidis (Center for Axion and Precision Physics Research, IBS)

CAST prepares to leap further into the dark sector following successful installation of new resonant microwave cavities.

First SWAN workshop at CERN

by Enric Tejedor Saavedra (CERN)

The meeting offered the opportunity to share use experiences and better understand how the service is used and how it could evolve to suit the community needs.

Shining more light on the onset of deconfinement

by Maciej P. Lewicki and Ludwik Turko (University of Wrocław) on behalf of the NA61/SHINE Collaboration

Latest results from the NA61/SHINE experiment contribute to the quest for understanding the phases of strongly interacting matter while the collaboration plans the next steps.

AMVA4NewPhysics legacy in searches for new physics

by Anna Stakia (CMS, CERN)

The MSCA project AMVA4NewPhysics has made important contributions in developing advanced tools and training the next generation of scientists to work with vast amounts of data whether searching for new physics or developing industrial applications.
