[YSF] Search for extra Higgs bosons through same-sign top-quark production in association with an extra jet
/ HSU, Ting-hsiang (Taiwan, Natl. Taiwan U.)
/CMS Collaboration
A search is presented for new Higgs bosons, targeting proton-proton (pp) collision events with a same-sign top quark pair associated with an extra jet via the processes pp$\rightarrow$tH/A$\rightarrow$tt$\bar{\text{c}}$ and pp$\rightarrow$tH/A$\rightarrow$tt$\bar{\text{u}}$, where H and A represent exotic scalar and pseudoscalar bosons, respectively. The study is based on data collected at a center-of-mass energy of 13 TeV with the CMS detector at LHC Run 2, corresponding to an integrated luminosity of 138 $\text{fb}^{-1}$. [...]

Test and performance of the CMS ECAL barrel data conversion and digital processing ASIC for HL-LHC
/ Borca, Cecilia (INFN, Turin ; Turin U.)
/CMS Collaboration
In preparation for the high luminosity upgrade of the Large Hadron Collider, a new data conversion and digital processing ASIC, called LiTE-DTU, was designed. Implemented in a 65 nm CMOS technology, the LiTE-DTU features two 12-bit 160 MS s$^{-1}$ successive approximation register time-interleaved ADCs, a data processing unit and enables efficient data transmission at 1.28 Gbps.
The LiTE-DTU has undergone extensive testing in both laboratory and beam tests, demonstrating excellent performance in the pre-production version, showing the production readiness of the design. [...]

Measurement of the ttbar cross-section and ttbarZ cross-section ratio in pp collisions at a centre-of-mass energy of 13.6 TeV with the ATLAS and CMS experiments
/ Ranken, Evan Altair (DESY)
/ATLAS and CMS Collaborations
Recent measurements of the inclusive ttbar production cross section, sigma_ttbar, and the ratio of ttbar to Z boson production, R_ttbar/Z, are presented by the CMS and ATLAS collaboration using data collected from proton-proton collisions at the new LHC operating energy of sqrt(s)=13.6 TeV. These are among the first results of the ongoing LHC Run 3 data-taking period, which began in 2022, and provide a first opportunity to measure changes in key physics observables following the increase in energy.

Latest VBS and VBF results with the ATLAS and CMS experiments
/ Camaiani, Benedetta (INFN, Florence ; Florence U.)
/ATLAS and CMS Collaborations
Vector Boson Scattering and Fusion processes are crucial to probe the electroweak sector of the Standard Model, as they are sensitive to self-couplings of vector bosons. This review summarizes the latest measurements of production cross sections of vector bosons in association with two jets, performed using data collected by the ATLAS and CMS experiments at $\sqrt{s} = 13$ TeV during the LHC Run 2 data taking period..
