$t\bar{t}Z$ cross section - Towards a differential measurement with the CMS experiment
Frühjahrstagung der Deutschen Physikalischen Gesellschaft - Teilchenphysik, DPG2018, Meeting locationWürzburg, Germany, 19 Mar 2018 - 23 Mar 20182018-03-192018-03-23  GO
The production of a top quark pair in association with a Z boson is a direct probe of the top quark–Z boson coupling and can now, as the LHC collects more and more data, be measured precisely.The CMS collaboration has reported a measurement of the ttZ cross section at √s=13 TeV with 35.9/fb of data recorded in 2016 that is in agreement with the Standard Model prediction. Extending this measurement with data (to be) recorded in 2017 and 2018, a first differential measurement will be possible. [...]

A DAQ Test System for the CMS Phase II Tracker Upgrade
Frühjahrstagung der Deutschen Physikalischen Gesellschaft - Teilchenphysik, DPG2018, Meeting locationWürzburg, Germany, 19 Mar 2018 - 23 Mar 20182018-03-192018-03-23  GO
For the upcoming high-luminosity phase of the LHC, the tracking detector of the CMS experiment has to be upgraded. Two types of detector modules are foreseen to be used for the outer tracker regions: so-called 2S and PS modules. [...]

The measurement of W-charge asymmetry at 13 TeV with the CMS detector
Frühjahrstagung der Deutschen Physikalischen Gesellschaft - Teilchenphysik, DPG2018, Meeting locationWürzburg, Germany, 19 Mar 2018 - 23 Mar 20182018-03-192018-03-23  GO
In pp collisions at the LHC, rates of ud ̄ annihilation dominate over du ̄. Consequently, W+ boson production prevails over W− , which results in an effect called W charge asymmetry, A [...]

Top Quark Physics at the LHC : Probing the Energy Frontier
Frühjahrstagung der Deutschen Physikalischen Gesellschaft - Teilchenphysik, DPG2018, Meeting locationWürzburg, Germany, 19 Mar 2018 - 23 Mar 20182018-03-192018-03-23  GO
The top quark is the heaviest known elementary particle and the only quark that decays before hadronising, and thus gives direct access to its properties. With its large mass, it plays a crucial role for testing the predictions of the Standard Model (SM) and in the measurement of the Higgs boson properties. [...]

Hunting the Dark Higgs
Frühjahrstagung der Deutschen Physikalischen Gesellschaft - Teilchenphysik, DPG2018, Meeting locationWürzburg, Germany, 19 Mar 2018 - 23 Mar 20182018-03-192018-03-23  GO
The dark Higgs model is an extension of the Standard Model (SM) that describes the phenomenology of dark matter while respecting the SM gauge symmetries. Besides adding a fermionic dark matter candidate to the SM, it intro- duces a new vector boson (Z’) along with a new scalar, the dark Higgs particle. [...]

Lorentz Angle Measurement in irradiated CMS Pixel Sensors
Frühjahrstagung der Deutschen Physikalischen Gesellschaft - Teilchenphysik, DPG2018, Meeting locationWürzburg, Germany, 19 Mar 2018 - 23 Mar 20182018-03-192018-03-23  GO
Since the replacement of the CMS experiment’s pixel detector in the extended 2016/17 shutdown, the detector modules have already been exposed to a significant dose of radiation. The modules’ built-in readout chips and silicon sensors are designed for operation at LHC design luminosity without efficiency losses and are tested to be fully functioning up to radiation doses above the expected lifetime dose.
