Axion-like particle searches at the LHC
Axion-like particle searches at the LHC The Standard Model (SM) of Particle Physics is plagued by some longstanding conceptual and practical questions, and we have to go beyond the Standard Model to address them. A guiding principle of the Standard Model is that we should expect to see all processes which are consistent with its

CERN – HEP Software Foundation participates in Google’s Summer of Code 2018
CERN – HEP Software Foundation participates in Google's Summer of Code 2018 Google Summer of Code (GSoC) allows students to contribute to development of open-source projects, mentored by participating organizations. CERN-SFT participates in GSoC since 2011. In 2017, the programme expanded to involve the whole high-energy physics community, in particular by creating a GSoC umbrella

Anti-nuclei in the cosmos and at the LHC
Anti-nuclei in the cosmos and at the LHC The ALICE collaboration has recently released several measurements on the production of anti-deuterons and anti-3He in proton-proton and Pb-Pb collisions at LHC energies. These results are not only interesting for the study of the hot QCD medium produced in heavy- ion collisions, but they also provide crucial

Mapping the CMS inner tracking system with unprecedented precision
Mapping the CMS inner tracking system with unprecedented precision In an experiment like CMS, it is important to know where all the detector material is. For example, in order to properly simulate the detector response, you need to know not only where the sensors are, but also the locations of the inactive material. Suppose you

VeloPix, a new hybrid pixel readout ASIC for the LHCb upgrade
VeloPix, a new hybrid pixel readout ASIC for the LHCb upgrade The LHCb-VELO group, which is composed of several institutes from the UK, Spain, Netherlands, Russia, Brazil and CERN are constructing an upgraded version of the VErtex LOcator (VELO) to be installed and commissioned during the long shutdown LS2 in 2019/2020. Unlike the currently operating

ATLAS presents a strategy for a general search of new physics
ATLAS presents a strategy for a general search of new physics One of the main goals of the Large Hadron Collider is to look for signals beyond the Standard Model (the other major goal has already been fulfilled with the discovery of the Higgs boson). To this day scientists are still lacking clues. Could it

LHCb experiment helping space-based experiments
LHCb experiment helping space-based experiments The study of antiprotons in cosmic rays is an exciting field of research today. Cosmic ray antiprotons are believed to be produced when the high-energetic particles interact with the interstellar gas forming secondary particles. Such collisions are expected to produce a certain limited number of antiprotons, thus offering an explanation

Experimental searches for solar and dark matter axions
Experimental searches for solar and dark matter axions Detection of solar axions If axions exist, they would be produced in large quantities in the solar interior. Photons from the solar plasma would convert into axions in the Coulomb fields of charged particles via the Primakoff axion-photon conversion. Once produced, axions get out of the star

Interview with Roberto Peccei
Interview with Roberto Peccei BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/interview-roberto-peccei) Roberto Peccei, is a world renowned theoretical physicist working in the interface between astroparticle physics and cosmology. He is probably best known for his work on strong CP violation. Together with Helen Quinn, Peccei suggested a mechanism to address the strong CP problem,

A Q&A with Pierre Sikivie
A Q&A with Pierre Sikivie In discussion with Pierre Sikivie, Distinguished Professor at the University of Florida, on the invention of experimental techniques for axion searches that can address some of the most pressing questions in modern physics. Sikivie played a crucial role in the development of experimental techniques for axion searches and laid the
