Tracker alignment performance in early 2023

In this report, the performance of the CMS tracker alignment in 2023 from the beginning of data taking till the month of June is described. The performance of the tracker geometries resulting from four different sets of alignment constants: (1) 2022 geometry, alignment constants from the previous da...

description In this report, the performance of the CMS tracker alignment in 2023 from the beginning of data taking till the month of June is described. The performance of the tracker geometries resulting from four different sets of alignment constants: (1) 2022 geometry, alignment constants from the previous data-taking year 2022, used as starting geometry for first tracker detector alignment of 2023, (2) first alignment in 2023 with cosmic rays collected at 3.8T magnetic field, (3) alignment with cosmic rays and pp collisions at center of mass energy of 900 GeV, and (4) alignment with cosmic rays and pp collisions at center of mass energy of 13.6 TeV, is compared. The data-driven methods used to derive the alignment parameters and the set of validations that monitor the performance of physics observables after the alignment are presented.
