Active projects
CMS Tracker commissioning and performance assessment
Christophe Delaere

The CMS silicon strip tracker is the largest device of its type ever built. There are 24244 single-sided micro-strip sensors covering an active area of 198m2.
Physics performance of the detector are being constantly assessed and optimized as new data comes.
Members of UCL are playing a major role in the understanding of the silicon strip tracker and in the maintenance and development of the local reconstruction code.

Properties of ttW and ttH production
Anna Benecke, Andrea Giammanco, Oguz Güzel, Jindrich Lidrych, Tu Thong Tran

We take advantage of the large statistics already recorded in Run 2 and being recorded in Run 3 by the CMS experiment to launch a systematic study of cross section, angular asymmetries and other properties in the ttW and ttH processes, which have a potentially large sensitivity to non-SM effects.
In synergy with the CP3 phenomenology group, we aim at reporting our results in a form that can be easily translated in EFT constraints.

External collaborators: CMS collaboration.
