A word from the Deputy Department Head of EP - September 2020
Dear Colleagues, dear Members of the EP Department and CERN Users,
Welcome to the autumn edition of the EP Newsletter, as the change of weather heralds the new season. You will notice that the look and feel has changed a little, as this is the first that follows the new standard for websites at CERN...

Chips on a ladder: end of production for ALICE-MFT
After more than four years of research and development, design and manufacturing work, the MFT (Muon Forward Tracker), a new detector that will equip the ALICE experiment at the LHC, has seen its construction finalized and is currently under commissioning at CERN
Read MOREMADMAX prototype test at CERN
The MAgnetized Disk and Mirror Axion eXperiment (MADMAX) experiment, based on the concept of a dielectric haloscope, aims to use this approach to close the sensitivity gap in the well-motivated range for dark-matter axions.
Read MOREClosing the gap between beam dump and colliders ALPs searches with NA64
A significant number of experiments, currently running planned for the near future, provide exciting opportunities in the search for axion-like particles that can answer some of the outstanding questions of the Standard Model, particularly those related to dark matter or the dark sector of the Universe.

First direct structural evidence and quantification for implanted Sn in the SnV “split-vacancy” configuration with ISOLDE deepens our understanding of their applications in processing and communication of quantum information and metrology.
Read MORECERN experiments find first evidence for rare Higgs boson decay
Physicists at CERN have been studying the Higgs boson since its discovery in 2012 and probe the properties of this very special particle by studying its different decay rates to other particles. Recently, CMS and ATLAS experiments announced new results which provide first evidence that the Higgs boson decays into two muons.

Random Number Generators for Precision Monte Carlos
We are entering into an exciting time in the long history of random numbers as modern Random Number Generators are based on theory of mixing in classical mechanical systems, thus allowing to understand where the randomness comes from, and in a sense measure this randomness.
Read MOREWhat is the likelihood function, and how is it used in particle physics?
In the context of experimental particle physics, “collisions” or “decays” are governed by the laws of quantum mechanics, which intrinsically describe probabilities.The laws and parameters within them must be inferred from experimental data with associated uncertainties. The likelihood function is a central tool for doing so within the main methods of statistical inference.
Read MORESystematic uncertainties: the new target of Machine Learning for HEP
Machine learning methods offer multiple benefits in data analysis for particle physics and beyond. The next frontier in experimental physics research calls for the exploitation of new technologies not only for the accurate reconstruction of particle signals but also for a holistic approach in the design of future detectors.
