ATLAS experiment revamps activities
ATLAS entered the COVID-19 lock down on the 17th of March 2020; the closing of the activities was very fast and efficient. During the lock down, still many activities were performed remotely, among them the development of the firmware…
Read moreArtificial neural networks shed light on rare SM processes.
In a new paper released last month, the ATLAS Collaboration reported the observation of a single top quark produced in association with a Z boson (tZq) using the full Run-2 dataset, thereby confirming earlier results by ATLAS and…
Read moreATLAS and CMS joint bootcamp for analysis preservation
Last month, 30 young graduate students and postdocs gathered at CERN to attend the first joint ATLAS+CMS analysis preservation bootcamp, organised by Sam Meehan, Clemens Lange, Lukas Heinrich (CERN), and Savannah Thais (Princeton). Over the course…
Read moreExploring the Lifetime Frontier at the LHC and Beyond
By any reasonable measure, the first ten years of the LHC have been an unmitigated success. But are we exploring everywhere in our data? The overwhelming majority of the searches for particles beyond the Standard Model (BSM) conducted at…
Read moreScientific data management with Rucio
Today's scientific experiments are manifold and diverse in their objectives, size, and workflows. However, one commonality uniting most, if not all, scientific experiments is the creation and analysis of data. Managing these scientific datasets is…
Read moreRECAST: A framework for reinterpreting physics searches at the LHC
On 22 of December 2015 a SpaceX rocket launched towards space delivering satellites to low Earth orbit and then, instead of being lost to the depths of the ocean, the rocket’s first stage -- the most expensive component of a rocket --…
Read moreLatest results from the Higgs boson couplings to second-generation fermions
The discovery of the Higgs boson completes the Standard Model, a very successful theory describing particles of visible matter and their interactions. However, there are still big missing pieces in our fundamental understanding of matter, while…
Read moreATLAS NSW Upgrade: preparing installation and commission of its first sector
The New Small Wheel (NSW) Upgrade it the most complex and challenging Phase-1 Upgrade project of ATLAS. As all the other upgrade projects for the LHC experiments, the goal is to meet the challenges of the High-Luminosity LHC era and to cope with the…
Read moreThe Higgs boson as a probe for new physics
The discovery of the Higgs boson has ushered in a new era of exploration at the Large Hadron Collider (LHC). Persistent tensions in the Standard Model (SM) of particle physics compel us to seek out physics beyond the SM (BSM) at the TeV scale, and…
Read moreATLAS trigger system meets the challenges of Run 2
The trigger system is an essential component of any collider experiment as it is responsible for deciding whether or not to keep an event from a given bunch-crossing interaction for later study. During Run 2 (2015 to 2018) of the Large Hadron…
