Data preservation and reproducibility at the LHCb experiment at CERN
… in data science at the Large Hadron Collider at CERN. In particular, provenance capture of the experimental data and the reproducibility of physics analyses at the LHCb experiment were studied. First, the preservation of the software and hardware dependencies of the LHCb experimental data and …

Long-term Performance of a concrete-lined Tunnel at CERN
… largest physics centre for nuclear research (CERN) under controlled laboratory conditions, two high-energy particle beams travel close to the speed of light around the most powerful particle accelerator ever built. The accelerator runs through a deep network of underground tunnels and caverns. …

Physics performance studies for the ALICE experiment at the CERN LHC
The ALICE experiment at the CERN Large Hadron Collider (LHC) will explore a primordial state of matter that existed in the early Universe. Resonance production at the LHC is of great interest in the study of the phase state of hadronic matter known as Quark Gluon Plasma (QGP). Results are presented …

Local Signal Processing of the ALICE Transition Radiation Detector at LHC (CERN)
… of the heavy ion experiment ALICE at LHC (CERN) integrates parts of the data acquisition and trigger system. Therefore, a multi chip module has been developped which incorporates two microchips. Detector signals are preamplified and shaped (Preamplifier and Shaper Chip, PASA). Thereafter …

Measurement of 50Cr and 53Cr Neutron Capture Cross Sections for Nuclear Technology at CERN n_TOF and HiSPANoS
… was performed at the n_TOF facility of CERN (Switzerland), in which the capture yield of both isotopes was measured and a new set of resonance parameters has been proposed. In addition, for the first time a neutron activation measurement of 50Cr was performed at the HiSPANoS facility of …

Strange particle and antiparticle production in Proton-Beryllium interactions at 40 GeV/c at the CERN NA57 Experiment
… data were obtained by the NA57 experiment at the CERN SPS in the 1999 data taking period. A comprehensive study of yields and transverse mass spectra for each of the three particle species is given. The results are compared to Pb-Pb data at 40 A GeV/c. In particular, the yields per wounded nucleon …

The missing bucket system : a fast switch and modulator to be applied to the CERN Intersecting Storage Rings
An electronic system is described, the object of which is to suppress an integral number (normally 10) of the 30 cycles of RF accelerating signal which correspond to one turn of a proton beam around the ISR.

Analysis of 3D silicon pixel vertex detector damage effects due to radiation levels present in the LHC at CERN
In high energy physics experiments, very high precision tracking of charged particles is needed. Solid state detectors achieve the high precision necessary to provide track and vertex reconstruction of the particles that traverse them, but tracking performance begins to deteriorate at fluxes of …

A Topological Search for Beyond the Standard Model Light Bosons Decaying into Muon Pairs with the CMS Detector at the CERN LHC
… into muon pairs with the CMS detector at the CERN LHC is presented. The analysis uses the full dataset recorded by the CMS detector during the 2015, sqrt(s) = 13 TeV, proton-proton data taking campaign of 2.83 fb^−1 to search for new, possibly long-lived, light bosons with a mass between 0.25 …

Reconstruction of CNGS neutrino events in the emulsions of the OPERA experiment
… of ν_mu -> ν_tau oscillations in the CNGS (CERN Neutrinos to Gran Sasso) neutrino beam produced at CERN; since the ν_e contamination in the CNGS beam is low, OPERA will also be able to study the sub-dominant oscillation channel ν_mu -> ν_e. OPERA is a large scale hybrid apparatus divided in …
