Fiber Bragg Grating (FBG) sensors as flatness and mechanical stretching sensors
D. Abbaneo, M. Abbas, M. Abbrescia +153
A novel approach which uses Fibre Bragg Grating (FBG) sensors has been utilised to assess and monitor the flatness of Gaseous Electron Multipliers (GEM) foils. The setup layout and…
Performance of a Large-Area GEM Detector Prototype for the Upgrade of the CMS Muon Endcap System
D. Abbaneo, M. Abbas, M. Abbrescia +134
Gas Electron Multiplier (GEM) technology is being considered for the forward muon upgrade of the CMS experiment in Phase 2 of the CERN LHC. Its first implementation is planned for…
The (Z_2)^3 symmetry of the non-tri-bimaximal pattern for the neutrino mass matrix
E. I. Lashin, M. Abbas, N. Chamoun +1
In view of the recent neutrino oscillation data pointing to a non-vanishing value for the smallest mixing angle (), we derive and find explicit realizations of the …
Tailoring the physical properties of poly(3-Hexylthiophene) thin films using electro-spray deposition

Performance of a Triple-GEM Demonstrator in Collisions at the CMS Detector
M. Abbas, M. Abbrescia, H. Abdalla +178
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…
Test Beam Performance Measurements for the Phase I Upgrade of the CMS Pixel Detector
M. Dragicevic, M. Friedl, J. Hrubec +481
A new pixel detector for the CMS experiment was built in order to cope with the instantaneous luminosities anticipated for the Phase~I Upgrade of the LHC. The new CMS pixel detecto…
