Roberto Peccei and Helen Quinn worked together in developing what is today known as the Peccei-Quinn symmetry; a mechanism that addresses the strong CP-violation that consequently led to the invention of axions and inspired an intense experimental…
Read MOREQCD, the theory of strong interactions allows the violation of CP symmetry that would result in a non-zero value for the neutron electric dipole moment. Current measurements constrain the neutron EDM to be one trillionth of the size predicted by QCD…
Read MOREThe High Luminosity Large Hadron Collider (HL-LHC) entails a substantial upgrade of the CMS tracking system, to cope with much more demanding requirements and to implement additional functionalities. One of the main challenges for the experiments is…
Read MOREThe 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…
Read MOREGoogle 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…
Read MOREThe 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…
Read MOREIn 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…
Read MORE*/ 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…
Read MOREThe 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…
Read MOREDetection 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…
