This chapter of the report "Flavor in era LHC" Workshop discusses theoretical, phenomenological and experimental issues related to flavor phenomena charged lepton sector conserving CP-violating processes. We review current limits main theoretical models for structure fundamental particles. analyze consequences available data, setting constraints on explicit beyond standard model, presenting benchmarks discovery potential forthcoming measurements both at LHC low energy, exploring options...
For the high luminosity upgrade of LHC at CERN, ATLAS is considering addition a High Granularity Timing Detector (HGTD) in front end cap and forward calorimeters |z|= 3.5 m covering region 2.4 <|η|< 4 to help reducing effect pile-up. The chosen sensors are arrays 50 μm thin Low Gain Avalanche Detectors (LGAD). This paper presents results on single LGAD with surface area 1.3×1.3 mm2 2×2 pads or 3×3 each different implant doses p+ multiplication layer. They obtained from data collected during...
Simplified Template Cross Sections (STXS) have been adopted by the LHC experiments as a common framework for Higgs measurements. Their purpose is to reduce theoretical uncertainties that are directly folded into measurements much possible, while at same time allowing combination of between different decay channels well experiments. We report complete, revised definition STXS kinematic bins (stage 1.1), which be used upcoming ATLAS and CMS using full Run 2 datasets. The main focus on three...
The authors describe a VLSI processor for pattern recognition based on content addressable memory (CAM) architecture, optimized on-line track finding in high-energy physics experiments. A large CAM bank stores all trajectories of interest and extracts the ones compatible with given event. This task is naturally parallelized by architecture able to output identified trajectories, searching matches 96-bit wide patterns, just few 40-MHz clock cycles. We have developed this device (called...
We study the impact of differential isolated-photon+jet cross sections measured in proton-proton collisions at a center-of-mass energy sqrt{s} = 7 TeV on parton distribution functions (PDF) proton. Next-to-leading order perturbative QCD (pQCD) calculations complemented with NNPDF2.1 densities, and Bayesian PDF reweighting method are employed. find that although current data provide only mild constraints to future gamma-jet measurements reduced experimental uncertainties can improve our...
Results of beam tests with planar silicon pixel sensors aimed towards the ATLAS Insertable B-Layer and High Luminosity LHC (HL-LHC) upgrades are presented. Measurements include spatial resolution, charge collection performance sharing between neighbouring cells as a function track incidence angle for different bulk materials. n-in-n presented fluence irradiations. Furthermore p-type from several vendors slightly differing layouts were tested. All tested connected by bump-bonding to Pixel...
We report on further developments of our recently proposed design approach for a full in-pixel signal processing chain deep n-well (DNW) MAPS sensors, by exploiting the triple well option CMOS 0.13 μm process. The optimization collecting electrode geometry and re-design analog circuit to decrease power consumption have been implemented in two versions APSEL chip series, namely "APSEL3T1" "APSEL3T2". results characterization 3x3 pixel matrices with output photons from <sup...
The Italian silicon-detectors-with-low-interaction-with material collaboration (SLIM5) has designed, fabricated and tested several prototypes of CMOS monolithic active pixel sensors (MAPS).

Also, MAPS emulator software toool presented. project aimed at...
A different approach to the design of CMOS MAPS has recently been proposed. By exploiting triple well option a commercial process, deep n-well (DNW) sensor realized with full in-pixel signal processing chain: charge preamplifier, shaper, discriminator and latch. This readout beeing compatible data sparsification will improve speed potential sensors. The first protoype chips, STMicroelectronics 130 nm proved new proposed for DNW is viable good sensitivity photons from <sup...
Modern experiments search for extremely rare processes hidden in much larger background levels. As the experiment complexity, accelerator backgrounds and luminosity increase we need increasingly exclusive selections to efficiently select events inside huge background. We present a fast, high-quality, track-based event selection self-triggered SLIM5 silicon telescope. This is an R&D whose innovative trigger will show that high rejection factors manageable rates can be achieved using...
We developed monolithic active pixel detectors that exploit the triple well option of CMOS 130 nm technology to implement analog and digital signal processing at level. The charge collecting element is realized using deep N-well (DNW) partially overlaps circuit. With this scheme we were able a full in-pixel chain, composed preamplifier, shaper, discriminator, latch. This approach has been validated by first prototype (APSEL0), report here on extensive measurements performed second (APSEL1),...
