The summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,717 new measurements 869 papers, we list, evaluate, average measured properties gauge bosons the recently discovered Higgs boson, leptons, quarks, mesons, baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle search limits are listed in Summary Tables. give numerous tables, figures, formulae, reviews topics...
This document is the final report of ATLAS-CMS Dark Matter Forum, a forum organized by ATLAS and CMS collaborations with participation experts on theories Matter, to select minimal basis set dark matter simplified models that should support design early LHC Run-2 searches. A prioritized, compact benchmark proposed, accompanied studies parameter space these repository generator implementations. also addresses how apply Effective Field Theory formalism for collider searches present results...
In this work, we consider the case of a strongly coupled dark/hidden sector, which extends Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions generally contain matter fields, much like SM quarks, and fields similar to gluons. We focus on exploration such sectors where dark particles are produced at LHC through portal undergo rapid hadronization within sector before decaying back, least in part potentially with sizeable lifetimes, particles, giving range...
The Apollo Advanced Telecommunications Computing Architecture (ATCA) platform is an open-source design consisting of a generic "Service Module" (SM) and customizable "Command (CM), allowing for cost-effective use in applications such as the readout inner tracker Level-1 track trigger CMS Phase-II upgrade at HL-LHC. SM integrates intelligent IPMC, robust power entry conditioning systems, powerful system-on-module computer, flexible clock communication infrastructure. CM designed around two...

Abstract The upgrade of the CMS experiment for high luminosity operation LHC comprises replacement current endcap calorimeter by a granularity sampling (HGCAL). electromagnetic section HGCAL is based on silicon sensors interspersed between lead and copper (or tungsten) absorbers. hadronic uses layers stainless steel as an absorbing medium active in regions radiation exposure, scintillator tiles directly read out photomultipliers remaining regions. As part development detector its readout...
The Compact Muon Solenoid (CMS) experiment operating at the CERN (European Laboratory for Nuclear Physics) Large Hadron Collider (LHC) is in process of upgrading several its detector systems. Adding more individual components brings need to test and commission those separately from existing ones so as not compromise physics data-taking. CMS Trigger, Timing Control (TTC) system had reached limits terms number separate elements (partitions) that could be supported. A new Distribution System...
During the LHC Long Shutdown 1, CMS Data Acquisition (DAQ) system underwent a partial redesign to replace obsolete network equipment, use more homogeneous switching technologies, and support new detector back-end electronics. The software hardware infrastructure provide input, execute High Level Trigger (HLT) algorithms deal with output data transport storage has also been redesigned be completely file- based. All metadata needed for bookkeeping are stored in files as well, form of small...
The data acquisition system (DAQ) of the CMS experiment at CERN Large Hadron Collider (LHC) assembles events a rate 100 kHz, transporting event an aggregate throughput more than 100GB/s to Highlevel Trigger (HLT) farm. HLT farm selects and classifies interesting for storage offline analysis output around 1 kHz. DAQ has been redesigned during accelerator shutdown in 2013-2014. motivation this upgrade was twofold. Firstly, compute nodes, networking infrastructure were reaching end their...
The challenging conditions of the High-Luminosity LHC require tailored hardware designs for trigger and data acquisition systems. Apollo platform features a "Service Module" with powerful system-on-module computer that provides standard ATCA communications application-specific "Command Module"s large FPGAs high-speed optical fiber links. CMS version will be used track finder pixel readout. It up to two more than 100 links speeds 25\,Gb/s. We study carefully design performance board by using...
As part of its HL-LHC upgrade program, the CMS collaboration is replacing existing endcap calorimeters with a high-granularity calorimeter (CE). The new sampling unprecedented transverse and longitudinal readout for both electromagnetic hadronic compartments. Due to compactness, intrinsic time resolution, radiation hardness, silicon has been chosen as active material regions exposed higher levels. sensors are fabricated 20 cm (8") wide hexagonal wafers segmented into several hundred pads...
The upgraded High Luminosity LHC, after the third Long Shutdown (LS3), will provide an instantaneous luminosity of 7.5 × 1034 cm−2s−1 (levelled), at price extreme pileup up to 200 interactions per crossing. In LS3, CMS Detector also undergo a major upgrade prepare for phase-2 LHC physics program, starting around 2025. detector be read out unprecedented data rate 50 Tb/s and event 750 kHz. Complete events analysed by software algorithms running on standard processing nodes, selected stored...
In order to accommodate new back-end electronics of upgraded CMS sub-detectors, a FEROL40 card in the microTCA standard has been developed. The main function is acquire event data over multiple point-to-point serial optical links, provide buffering, perform protocol conversion, and transmit TCP/IP streams (4x10Gbps) Ethernet network aggregation layer DAQ (data acquisition) builder.

The primary goal of the online cluster Compact Muon Solenoid (CMS) experiment at Large Hadron Collider (LHC) is to build event data from detector and select interesting collisions in High Level Trigger (HLT) farm for offline storage. With more than 1500 nodes a capacity about 850 kHEPSpecInt06, HLT machines represent similar computing all CMS Tier1 Grid sites together. Moreover, it currently connected CERN IT datacenter via dedicated 160 Gbps network connection hence can access remote EOS...
