Search for Physics beyond the Standard Model in four- and three-top quark production
/ Shooshtari, Maryam (OAW, Vienna)
/CMS Collaboration
A reinterpretation of four-top quark ($t\bar{t}t\bar{t}$) production is presented using the full Run~2 dataset recorded by the CMS experiment, corresponding to an integrated luminosity of 138\,fb$^{-1}$. The analysis targets BSM scenarios using the existing \tttt production measurement, including constraints on effective field theory (EFT) operators, top-philic heavy resonances, and the top-Yukawa coupling.

Review of the performance of the CMS hadron calorimeter
/ Wei, Yide (Nanjing Normal U.) ; Wang, Hui (Nanjing Normal U.)
/CMS Collaboration
The hadron calorimeter is a central component of the CMS detector, vital for measuring hadron energies and reconstructing missing transverse momentum. This paper reviews its performance before and after the Phase~1 upgrade (completed in 2019), which upgraded both back-end and front-end electronics, including photodetectors and charge-integrating ADC with precise-timing TDC, as well as its depth segmentation in the barrel and endcaps. [...]

Searches in CMS for new physics in final states with leptons
/ Kaur, Anureet (Panjab U.)
/CMS Collaboration
Many new physics models, such as the Sequential Standard Model, Grand Unified Theories, models of extra dimensions, or models like leptoquarks or vector-like leptons, predict heavy mediators at the TeV energy scale. We present recent results of such searches in leptonic final states obtained using data recorded by the CMS experiment during Run-II of the LHC..

Probing new physics with dedicated data streams at CMS
/ Simsek, Ali Eren (Catholic U. America)
/CMS Collaboration
Signatures of new physics at the LHC are varied and, by nature, often very different from those of Standard Model processes. Novel experimental techniques, including dedicated data streams, are exploited to enhance the sensitivity of the CMS Experiment to search for such signatures. [...]

/CMS Collaboration
In preparation for operations at the HL-LHC, the CMS Collaboration is upgrading its endcap calorimeters with a high granularity calorimeter (HGCAL). The HGCAL back-end electronics includes two Non-Zero Suppression (NZS) boards, which dynamically disable zero-suppression in designated regions of interest. [...]
