Abstract Fifty thousand hybrid circuits of five different types will be manufactured for the Phase-2 Upgrade CMS Outer Tracker. These must undergo a strict quality control process, composed functional testing and visual inspection, before they can assembled into modules. The hybrids functionally tested first at manufacturing site. Afterwards, visually inspected again CERN or collaborating institutes. Results from these processes stored in production database. This paper presents software...

At the High Luminosity LHC (HL-LHC), CMS experiment will need to operate at up 200 interactions per 25 ns beam crossing time and with 4000 fb −1 of integrated luminosity. To achieve physics goals needs improve tracking resolution ability selectively trigger on specific events. The tracker upgrade requires designing a new detector cope HL-LHC conditions. Outer Tracker is based two types silicon modules (strip-strip pixel-strip). Each module type has few high-density interconnect hybrid...

A search for a Standard Model Higgs boson decaying to b$\bar{\text{b}}$ produced in association with W or Z is reported the following channels: W(e$\nu$)H, W($\mu\nu$)H, W($\tau\nu$)H, Z($\mu\mu)$H, Z(ee)H, and Z($\nu\nu$)H. The performed on data samples corresponding integrated luminosities of 5.1 $\text{fb}^{-1}$ at $\sqrt{s} = 7$ TeV 18.9 8$ TeV, collected by CMS experiement LHC.

The study of the associated production vector bosons and jets constitutes an excellent testbench to check numerous QCD predictions. most recent measurements total differential cross sections produced in association with are presented. Differential distributions as function a broad range kinematical observables measured compared theoretical Final states boson can be also used electroweak-initiated processes, such fusion Z or W accompanied by pair energetic large invariant mass. these...
