A word from the EP Department Head - December 2020

Dear Colleagues in EP,

Welcome to this winter edition and final EP newsletter of this year.

What a year turns to its end! 2020 is a year we will never forget. Following a smooth start to the year, in March everything turned upside down and since then we are in the grip of the pandemic. But it is so typical for CERN and the ingenuity and dedication of its personnel, that we have found ways to continue working despite the huge difficulties...

Preparing the future of the Physics Beyond Colliders (PBC) studies

Following the successful completion of EPPSU in 2020, it is now time to revisit the proposed PBC projects and to prepare their future in light of the European Strategy recommendations.

Hunting for axion-like particles at neutrino detectors

A wide range of different beyond the Standard Model realizations incorporate axion like particles. A novel experimental setup for ALPs searches exploring the near detector potential of neutrino experiments, like DUNE or FASERν, could boost these searches.

Machine learning ushers in a new paradigm for particle searches at the LHC

A data-driven revolution has started with machine learning as its catalyst. LHC Olympics has been a starting point for a new chapter in collider physics that will produce exciting physics results from the current datasets as well from the datasets of the future at the LHC and beyond.

Results from the experiments

From COMPASS to AMBER: exploring fundamental properties of hadrons

Over the last two decades, the COMPASS experiment at CERN's North Area M2 beam line is playing a major role in the world-wide investigation of hadron structure and spectroscopy. In 2022, the AMBER collaboration will commence a new generation of experiments at the same beam line with the flagship goal to investigate fundamental questions connected to the emergence of hadron mass.

CMS GEMs are changing gear

The installation of GEMs (gas electron multiplier) detectors in CMS is rapidly advancing during LS2. The 144 additional muon detectors modules currently installed will help CMS to detect particles produced in the very forward region during the next run of the LHC.

The upgraded ALICE TPC

ALICE achieved a major milestone with the completion of the upgraded TPC following many years of intense R&D, construction and assembly. At the end of 2020, the commissioning of the new TPC was completed as ALICE gears up for Run 3 of the LHC.

PUMA: antiprotons to probe the surface of radioactive nuclei

The proposed PUMA experiment aims at transporting one billion antiprotons from ELENA to ISOLDE at CERN to perform the capture of low-energy antiprotons by short-lived nuclei, and probe in this way the so-far unexplored isospin composition of the nuclear-radial-density tail of radioactive nuclei.

Secrets of beta decay unraveled at ISOLDE

Recent ISOLDE results provide important constraints on theoretical models addressing the competition between allowed and first-forbidden β decays, important for the detailed understanding of the nucleosynthesis of heavy elements produced through the merging of neutron stars

Special Feature

Cornering right-handed neutrinos

The first full frequentist analysis of the extension of the Standard Model by three right-handed neutrinos offers, so far, the most comprehensive assessment of this model below the TeV scale and provides the ground for exploring the impact of searches at future experiments.

Uniting Leptogeneses

A recent paper shows that previously considered mechanisms of baryon asymmetry generation involving two right-handed Majorana neutrinos are actually united and moreover the parameter space can be accessible in planned intensity experiments or future colliders.
