Fast rotation of the N = Z nucleus 36Ar Open
A highly-deformed rotational band has been identified in the N = Z nucleus 36Ar. At high spin the band is observed to its presumed termination at Iπ = 16+, while at low spin it has been firmly linked to previously known states in 36Ar. Spi…

Benchmarking LHC background particle simulation with the CMS triple-GEM detector Open
In 2018, a system of large-size triple-GEM demonstrator chambers was installed in the CMS experiment at CERN's Large Hadron Collider (LHC). The demonstrator's design mimicks that of the final detector, installed for Run-3. A successful Mon…

Performance of a triple-GEM demonstrator in pp collisions at the CMS detector Open
After the Phase-2 high-luminosity upgrade to the Large Hadron Collider (LHC), the collision rate and therefore the background rate will significantly increase, particularly in the high η region. To improve both the tracking and triggering …

arXiv : Modeling the triple-GEM detector response to background particles for the CMS Experiment Open
An estimate of environmental background hit rate on triple-GEM chambers is performed using Monte Carlo (MC) simulation and compared to data taken by test chambers installed in the CMS experiment (GE1/1) during Run-2 at the Large Hadron Col…

Two years’ test of a temperature sensing system based on fibre Bragg grating technology for the CMS GE1/1 detectors Open
A temperature monitoring system based on fibre Bragg grating (FBG) fibre optic sensors has been developed for the gas electron multiplier (GEM) chambers of the Compact Muon Solenoid (CMS) detector. The monitoring system was tested in proto…

Detector Control System for the GE1/1 slice test Open
Gas Electron Multiplier (GEM) technology, in particular triple-GEM, was selected for the upgrade of the CMS endcap muon system following several years of intense effort on R&D. The triple-GEM chambers (GE1/1) are being installed at station…

Interstrip capacitances of the readout board used in large triple-GEM detectors for the CMS Muon Upgrade Open
We present analytical calculations, Finite Element Analysis modelling, and physical measurements of the interstrip capacitances for different potential strip geometries and dimensions of the readout boards for the GE2/1 triple-Gas Electron…

The Grimus–Neufeld Model with FlexibleSUSY at One-Loop Open
The Grimus–Neufeld model can explain the smallness of measured neutrino masses by extending the Standard Model with a single heavy neutrino and a second Higgs doublet, using the seesaw mechanism and radiative mass generation. The Grimus–La…

Erratum: Dose rate effects in the radiation damage of the plastic scintillators of the CMS hadron endcap calorimeter Open
Subsequent to the publication of this paper, one of the hybrid photodiodes used as the photode- tector was removed and highly localized damage on its photocathode was discovered. The study of the photodiode cathode was published in Review …

Operational Experience With the GEM Detector Assembly Lines for the CMS Forward Muon Upgrade Open
The CMS Collaboration has been developing large-area triple-gas electron multiplier (GEM) detectors to be installed in the muon Endcap regions of the CMS experiment in 2019 to maintain forward muon trigger and tracking performance at the H…

Dose rate effects in the radiation damage of the plastic scintillators of the CMS hadron endcap calorimeter Open
We present measurements of the reduction of light output by plastic scintillators irradiated in the CMS detector during the 8 TeV run of the Large Hadron Collider and show that they indicate a strong dose rate effect. The damage for a give…

Light neutrino mass spectrum with one or two right-handed singlet fermions added Open
We analyse two cases of the minimal extension of the Standard Model when one or two right-handed fields are added to the three left-handed fields. A second Higgs doublet (two Higgs doublet model – 2HDM) is included in our model. We calcula…
View article: A minimal seesaw model with the mu-tau symmetry
A minimal seesaw model with the mu-tau symmetry Open
We analyse a flavour model for a lepton sector which is based on type I seesaw mechanism, a Z_2 symmetry for lepton flavours, a mu-tau interchange symmetry and a CP symmetry. This model fits well the data of neutrino mass squared differenc…
