The University of Zurich group is a major contributor to the CMS inner Tracker. They helped build the Pixel Tracker that took data from 2009 to 2017 as well as the improved version with more tracking layers, less material and higher data rates capabilities, which was commissioned and installed in early 2017. The group has contributed to the calibration and maintenance of these systems since 2009. Currently, they are taking part in developing the next generation of the inner Tracker to be installed around 2025.

The group members are interested in the mass hierarchy of the Standard Model, and search for different physics between the heaviest and lightest particles. Some of the searches for new physics concentrate on finding evidence for dark-matter candidates as well as for signatures of extra spatial dimensions and new strong interactions. The group is involved in in-depth investigations of the Higgs boson’s properties and its relationship with the top quark. They develop techniques for identifying boosted bosons that decay to quarks, b-quarks, and tau leptons, in order to identify heavy new particles, and they originated and developed multivariate techniques for extracting maximal information about physics processes from collisions.

The current group in CMS consists of two professors, one senior scientist, six postdoctoral researchers, eight PhD students and four non-doctoral students.
