Measurement of the W gamma Production Cross Section in Proton-Proton Collisions at root s=13 TeV and Constraints on Effective Field Theory Coefficients

Konstantin Androsov, Matthias Finger, Jan Steggemann, Qian Wang, Yiming Li, Varun Sharma, Xin Chen, Arvind Shah, Rakesh Chawla, Jian Wang

A fiducial cross section for W gamma production in proton-proton collisions is measured at a center-of-mass energy of 13 TeV in 137 fb(-1) of data collected using the CMS detector at the LHC. The W -> e nu and mu nu decay modes are used in a maximum-likeli ...

The CMS Phase-1 pixel detector upgrade

Simone Scarfì, Qian Wang, Varun Sharma, Konstantin Androsov, Xin Chen, Rakesh Chawla, Tian Cheng, Werner Lustermann, Andromachi Tsirou, Andrea Rizzi

The CMS detector at the CERN LHC features a silicon pixel detector as its innermost subdetector. The original CMS pixel detector has been replaced with an upgraded pixel system (CMS Phase-1 pixel detector) in the extended year-end technical stop of the LHC ...

Beam test performance of prototype silicon detectors for the Outer Tracker for the Phase-2 Upgrade of CMS

Qian Wang, Simone Scarfì, Varun Sharma, Konstantin Androsov, Xin Chen, Tian Cheng, Werner Lustermann, Andromachi Tsirou, Andrea Rizzi, David Vannerom

A new CMS tracker detector will be installed for operation at the High Luminosity LHC (HL-LHC). This detector comprises modules with two closely spaced parallel sensor plates and front-end ASICs capable of transmitting tracking information to the CMS Level ...

The DAQ and control system for the CMS Phase-1 pixel detector upgrade

Qian Wang, Simone Scarfì, Varun Sharma, Chia-Chun Chen, Konstantin Androsov, Xin Chen, Tian Cheng, Werner Lustermann, Andromachi Tsirou, Andrea Rizzi

In 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1 pixel detector features four barrel layers in the central region and three disks per end in the forward regions. The upgraded pixel detector requires an upgraded data ac ...

Observation of the rare B-s(0)->mu(+)mu(-) decay from the combined analysis of CMS and LHCb data

Matthias Finger, Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Qian Wang, Frédéric Blanc, Yiming Li, Tatsuya Nakada, Varun Sharma

The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested experimentally. The probabilitie ...
