Il y a 30 ans Le Web naissait au CERN / Fluckiger, Francois
À l'occasion du 30e anniversaire de l'invention du Web, l'auteur, qui a succédé en 1974 à Tim Berners Lee quand celui-ci a quitté le CERN pour le MIT, explique les origines du Web, le contexte de l’Internet à l’époque de son invention, et corrige certaine idées reçues sur le genèse de cet immense avancée..

Le Web a été un accélérateur de l'irrationalité / Fluckiger, Francois
À l'occasion du 30e anniversaire de l'invention du Web, l'auteur, qui a succédé en 1974 à Tim Berners Lee quand celui-ci a quitté le CERN pour le MIT, reviens sur les origines de cette immense avancée, et explore ses conséquences sociétales : la prédominance croissante des systèmes de croyances sur les systèmes de connaissances c'est-à-dire sur La Science, et la montée de l'irrationalité.

The European Researchers’ Network / Fluckiger, Francois
In spite of what has often been said, the Internet is not a positive product of unconstrained liberalism, nor a product of the imagination of private enterprise which is free of the straightjacket of autocratic policy; neither could have accomplished something that both Governments and major institutions had failed to achieve..

Le réseau des chercheurs européens / Fluckiger, Francois
Contrairement à ce qui a souvent été dit, l'Internet n'est pas le produit positif du libéralisme débridé, de l'esprit d'entreprise privée qui, libéré du carcan des programmes étatiques, aurait réalisé ce que ni les gouvernements ni les grandes institutions n'avaient réussi. Non, la mise en place d'un réseau d'information mondial, fondé sur des normes universelles, est bel et bien le fruit de la recherche publique : Internet est le produit indirect des universités et laboratoires qui non seulement ont inventé la technologie, mais - fait plus rare - l'ont déployée en un réseau mondial opérationnel, au service des chercheurs..

Lepton Flavour Universality tests in b → clν decays at LHCb / Mohammed, Rizwaan (Oxford U.) /LHCb Collaboration
The Standard Model predicts that the electroweak couplings to the three charged leptons are identical. However, in the last decade, experimental measurements have suggested that semileptonic processes involving taus could have a slightly enhanced decay rate compared to their muonic counterparts. [...]

Running the Dual-PQC GAN on noisy simulators and real quantum hardware / Chang, Su Yeon (CERN ; Ecole Polytechnique, Lausanne) ; Agnew, Edwin (Cambridge U.) ; Combarro, Elías F (Oviedo U.) ; Grossi, Michele (CERN) ; Herbert, Steven (Cambridge U.) ; Vallecorsa, Sofia (CERN)
In an earlier work, we introduced dual-Parameterized Quantum Circuit (PQC) Generative Adversarial Networks (GAN), an advanced prototype of a quantum GAN. We applied the model on a realistic High-Energy Physics (HEP) use case: the exact theoretical simulation of a calorimeter response with a reduced problem size. [...]

Ensemble Models for Calorimeter Simulations / Jaruskova, K (CERN ; Prague, Tech. U.) ; Vallecorsa, S (CERN)
Foreseen increasing demand for simulations of particle transport through detectors in High Energy Physics motivated the search for faster alternatives to Monte Carlo-based simulations. Deep learning approaches provide promising results in terms of speed up and accuracy, among which generative adversarial networks (GANs) appear to be particularly successful in reproducing realistic detector data. [...]

CernVM-FS ephemeral publishers on Kubernetes / Valenzuela, Andrea (CERN) ; Blomer, Jakob (CERN)
The CernVM File System (CernVM-FS) is a global read-only POSIX file system that provides scalable and reliable software distribution to numerous scientific collaborations. It gives access to more than a billion binary files of experiment application software stacks and operating system containers to end user devices, grids, clouds, and supercomputers. [...]

Extending the distributed computing infrastructure of the CMS experiment with HPC resources / CMS Collaboration
Particle accelerators are an important tool to study the fundamental properties of elementary particles. Currently the highest energy accelerator is the LHC at CERN, in Geneva, Switzerland. [...]

The LHCb Mighty Tracker / Padeken, Klaas (Bonn U., HISKP) /LHCb Mighty Tracker Group Collaboration
During the long shutdown 4 of the LHC the instantaneous luminosity will be increased by a factor of $\approx 10$ to $1.5\cdot 10^{34} \text{cm}^{-2}\text{s}^{-1}$. The expected data recorded with the LHCb detector will increase from 50 $\text{fb}^{-1}$ to 300 $\text{fb}^{-1}$. [...]
