This 16-month shutdown was ended, and full-scale participation of the T2_UA_KIPT center in the CMS grid infrastructure was resumed starting from July 2023. The center's functioning quality determined by readiness to participate in the data processing reached 90.8% 5 months after the resumption of work, and the facility belongs to the group of the most reliable CMS T2 centers. A high rate (up to 10 Gbps) is provided for transfers of the CMS experimental information to the center for processing. The usage of facility’s computing resources for the 5 months was 15.4 thousand kHEPscore23-hours. This is close to the pre-war level of the facility's resources usage intensity and is 100% (99.99%) of consumption of the Ukrainian grid infrastructure [NGI_UA] resources by the virtual organizations (VOs) associated with the LHC (all VOs in general). With the use of the WLCG/CMS grid infrastructure, the processing of samples of proton-proton collisions at an energy of 13 TeV, obtained in the CMS experiment, was continued with the aim of searching for the supersymmetry signal (SUSY) – the direct chargino pair production.  Product Description popup.authors Kovalyova Lyudmila Semenivna Кurov Oleksiy O.
