ATLAS
Artificial 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 CMS using smaller…
Read moreHeterogeneous 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,…
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 moreDeep Neural Networks for particle reconstruction in high-granularity calorimeters
Precision measurements in high energy physics as well as an increasing amount of searches for new phenomena rely on a precise reconstruction of the event that caused a particular signature in the detector. Particle flow algorithms [1, 2, 3, 4] aim to…
Read moreAMVA4NewPhysics legacy in searches for new physics
*/ A couple of months ago, the four-year life cycle of AMVA4NewPhysics, a Horizon2020-funded Marie Skłodowska-Curie Innovative Training Network (ITN), in which CERN participated as one of the member institutions, was completed. With the ultimate…
Read moreRe-discovering the Higgs boson in the Cloud
It’s hard to believe that it has already been more than seven years since the discovery of the Higgs boson. Since then, numerous papers have been published by the ATLAS and CMS collaborations measuring the long-awaited particle’s properties in…
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 ATLAS and…
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 -- returned…
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…
