Searching for camouflaged dark sectors
Searching for camouflaged dark sectors The masses of particles are some of the fundamental parameters of nature, and their precise measurement remains a key experimental challenge. However, when propagating through a medium, environmental effects can change the effective mass of a particle, leading to interesting phenomenology. One Standard Model (SM) example of this occurs when

Discussing the physics of feebly-interacting particles
Discussing the physics of feebly-interacting particles FIPs are any kind of beyond-the-Standard Model (BSM) particles with couplings much less than one, consisting of such well-known phenomena as dark matter (DM), axions / axion-like particles (ALPs), heavy neutral leptons (HNLs), and dark photons. While the first edition of the FIPs workshop series, FIPs 2020 [ https://indico.cern.ch/e/FIPs_2020

Spotlight on Hybrid Pixel Sensors
Spotlight on Hybrid Pixel Sensors Prelude Making the next pivotal discovery in particle physics depends on our ability to build new experiments aiming at pushing the boundaries of energy and intensity frontiers. The process of designing and building such apparatuses often originates years before any breakthrough data can be collected. While experimental physicists are busy

Celebrating LGBTQ+ in STEM
Celebrating LGBTQ+ in STEM Over the past years, CERN constantly strives to implement inclusive policies for all, including for personnel who identify as LGBTQ+ and who dream to pursue a career in science, engineering and technology. Moreover, given its prestigious role as a world-leading research institute, CERN has a responsibility to lead and to foster

Higgs Boson Physics – The View Ahead
Higgs Boson Physics – The View Ahead The observation of electroweak symmetry breaking in nature implies the existence of Goldstone bosons that provide the longitudinal components of the massive W and Z gauge bosons. A priori, one could have imagined a plethora of possible dynamical models that produce the required Goldstone bosons. Remarkably, the simplest

Exploring the Higgs: A Personal Retrospective
Exploring the Higgs: A Personal Retrospective When I started my career as a theoretical physicist in the early 1980’s, the Higgs boson was not yet a topic of major theoretical interest. There was a long gap between the time when the Brout- Englert-Higgs mechanism was proposed and when people really started doing some hard calculations.

In discussion with Rolf-Dieter Heuer
In discussion with Rolf-Dieter Heuer Rolf-Dieter Heuer is no stranger to CERN, serving as Director General of the organization from 2009 to 2015. Previous to that, from 1984 to 1998, he was a staff member at the Laboratory, working for the OPAL collaboration at the Large Electron Positron collider (LEP) while between 1994 and 1998,

Deciphering the Electro-Weak Phase Transition at Current and Future Colliders
Deciphering the Electro-Weak Phase Transition at Current and Future Colliders Over the past century, a whole zoo of particles has been discovered and their interactions have been investigated. This led to a puzzling mystery; on the one hand we discovered a property of Nature, known as electro-weak symmetry, which gave a unified explanation of radioactive

Intelligent Design for Particle Detectors
Intelligent Design for Particle Detectors Particle detectors are becoming ubiquitous: originally designed as tools for fundamental physics (collider physics experiments, neutrino observatories, etc.), they are also increasingly used in medical and industrial applications. For all use cases, the main challenge in the design of a detector can always be described by the same terms: achieving

A new High-Granularity pre-shower detector for FASER
A new High-Granularity pre-shower detector for FASER The ForwArd Search ExpeRiment (FASER) is searching for new light and weakly interacting particles decaying into charged final states at the LHC [1][2]. While the first physics data taking has just started an upgrade is already foreseen to enhance the sensitivity also to Long-Lived Particles (LLP) decaying into
