After the 16-month break, processing of the LHC data at the T2_UA_KIPT center (and, accordingly, in Ukraine) was resumed. For 5 months (from the beginning of July 2023), the array of the CMS experimental information transferred to the center for processing has reached 1.24 PB, which exceeds the total facility’s disk storage capacity. The T2_UA_KIPT site operation and support in 2023 was taken into account by the CMS management as 5 FTE-months of contribution to the experiment. The CMS data analysis was continued to search for the SUSY signal – the direct chargino pair production in proton-proton collisions at an energy of 13 TeV. The results manifest a fair agreement between the CMS data and Standard Model calculations. Work within the CMS hadronic calorimetry upgrades was also continued. The stand for measurements of the light yield in scintillator samples was moved to a premise that was less damaged by the hostilities of 2022. Repair work was carried out on stand damaged components and electronic units, and also equipment installation and partial upgrade of the communication line between the stand and the PC have been fulfilled.
