The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on combined analysis proton-proton collision data at center-of-mass energies √s = 7, 8, and 13 TeV, corresponding to integrated luminosities up 5.1, 19.7, 35.9 fb^(-1), respectively. were collected the CMS detector CERN LHC. results statistically independent searches for bosons produced conjunction decaying pairs W bosons, Z photons, τ leptons, or bottom quark jets are maximize...
We report on the signal timing capabilities of thin silicon sensors when traversed by multiple simultaneous minimum ionizing particles (MIP). Three different planar sensors, with depletion thicknesses 133, 211, and 285 µm, have been exposed to high energy muons electrons at CERN. describe shape resolution measurements as well response these devices a function multiplicity MIPs. compare simulations where possible. achieve better than 20 ps for signals larger few tens
At the high luminosity LHC (HL-LHC) about 200 concurrent interactions are expected, with a spread between interaction vertices of few centimeters in beam direction and ps collision time. A time flight resolution order 30 would be able to reduce neutral particles pile-up contamination at calorimeter level one magnitude, restoring conditions similar what is routinely sustained current run . Micro-channel plates have been used PMT configuration as fast charged detector (resolution better than...
We describe our R&D effort to develop radiation-hard scintillating and wavelength shifting fibers by doping fused-silica with cerium. This new type of cerium-doped fiber potentially offers myriad applications in calorimeters for high-energy physics, tracking systems, profiling charged particle beams.
We have evaluated the performance of a Ce-doped fused-silica fiber as wavelength shifter coupled to CeF3 crystal using electron beams at CERN . The pulse shape and collection efficiency were measured irradiated (100 kGy) un-irradiated fibers. In addition, we light yield various fibers explored possibility them in future, including for precision timing applications high-luminosity collider environment.
Future high rate hadron colliders are expected to have hundreds of concurrent proton-proton interactions in the same bunch crossing, deteriorating energy resolution and identification capabilities calorimeters. The possibility distinguish neutral particles coming from different interaction vertices is being pursued as a tool reduce pile-up contamination calorimeters, restore optimal performance. A time flight order 20 ps will be able at calorimeter level by about one magnitude, restoring...
IMCP is an R&D project aimed at the exploitation of secondary emission electrons from surface microchannel plates (MCP) for fast timing showers in high rate environments. The usage MCPs "ionisation" mode has long been proposed and used extensively ion time-of-flight mass spectrometers. What not investigated depth their use to detect ionizing component showers. time resolution exceeds anything that previously calorimeters and, if exploited effectively, could aid event reconstruction...
