CERN Accelerating science

Welcome to the autumn issue of the EP newsletter!

It has been a busy and exciting summer with a wealth of new results presented by the LHC experiments at international conferences...

An Incredible Summer at CERN

by Kathryn Coldham

This summer, I had the extraordinary opportunity of being a CERN Summer Student. I was ecstatic when my CERN Summer School application had been accepted; I could not wait to contribute to cutting-edge research, attend the world-class Summer Student lectures, visit various CERN sites and meet people from around the world!

For the placement I worked alongside CERN intern Agustina Quesada, supervised by Dave Barney, EP-CMX group leader.  

In a paper published in Nature, the AWAKE collaboration reports the first ever successful acceleration of electrons using a proton-driven wave through a plasma.

ATLAS presented first results from a more generic strategy that allows searches for physics beyond the Standard Model that effectively minimizes the probability of missing any signs of new physics. 

Each summer CERN welcomes undergraduate students from all over the world to pursue research projects in physics or related science and technical disciplines. Meet them in this year's interactive map.

Measurement of antimatter production in p–He collisions helps to interpret astrophysics results from space-borne experiments and inaugurates a new research programme for the LHCb collaboration. 

Mapping the CMS inner tracking system with unprecedented precision

by Phil Baringer, Maxime Gouzevitch and Anna Kropivnitskaya

The CMS Collaboration’s 800th paper describes a technique for measuring the positions of inactive elements using Nuclear Interactions.

Last month, the ATLAS and CMS collaborations jointly announced the discovery of the Higgs boson decaying into a matter-antimatter pair of bottom quarks.

The ALICE experiment has recently released several measurements on the production of anti-deuterons and anti-3He that could help to understand AMS data. 

Designing a new readout ASIC called VeloPix, for the LHCb experiment. 

The rise of the axions!

by Panagiotis Charitos

In this issue, we interview Helen Quinn, Roberto Peccei and Pierre Sikivie on the ideas that led to the emergence of axions and inform current and future experimental concepts. 

Interview with Helen Quinn

by Panos Charitos

An interview with Helen Quinn about the steps that led to the formulation of the Peccei-Quinn mechanism and the value of science education for citizens. 

A sit down with Roberto Peccei, a world-renowned theoretical physicist, who together with Hellen Quin suggested a mechanism to solve the strong CP problem.  

 

In discussion with Pierre Sikivie, on the invention of experimental techniques for axion searches that can address some of the most pressing questions in modern physics. 

 

Searching for axions: old and new ideas

by Panagiotis Charitos

The last two decades, the efforts and size of the axion community have witnessed a real blossoming of ideas. 

OSQAR experiment sheds light on a hidden sector of CERN’s scientific heritage

by Pierre Pugnat on the behalf of the OSQAR collaboration

Two distinct OSQAR experiments at CERN, OSQAR-LSW and OSQAR-VMB look mostly for ALPS through studies of optical properties of the quantum vacuum permeated by a strong magnetic field

Developing new electronics for the CMS tracking system

by Panos Charitos. Kostas Kloukinas

An ongoing R&D programme aims to tackle the challenges of tracking and identifying new particles with the CMS detector in the challenging environment of HL-LHC. 

Experimental searches for solar and dark matter axions

Discussing the ongoing experimental searches for axions at CERN.
