Spectroscopy studies from the ATLAS and CMS experiments / Liang, Zhengchen (Tsinghua U., Beijing) ; Hu, Zhen (Tsinghua U., Beijing) /ATLAS and CMS Collaborations
Recent spectroscopy results from the ATLAS and CMS experiments at the LHC are shedding new light on the hadronic spectrum. These include the first precise measurements of the excited vector mesons $B^{+}$, $B^{0}$, and $B^{*0}_s$, alongside the observation of a new family of tetraquark candidates in the di-$J/\psi$ channel. [...]

Recent results in Higgs physics / Di Marco, Emanuele (INFN, Rome) /ATLAS and CMS Collaborations
This document summarizes recent results from ATLAS and CMS collaborations in the measurements of production cross section, decay rates, and determination of the properties for the Higgs boson, using proton-proton collision data from the LHC Run-2 and Run-3. The focus is on recent results using single Higgs boson production. [...]

Boosted t/H Highlight Talk / HSU, Ting-hsiang (Taiwan, Natl. Taiwan U.) /ATLAS and CMS Collaborations
The study of highly Lorentz-boosted objects has become a central component of the physics programs of both the ATLAS and CMS experiments. Such objects enable precision measurements of standard model processes and provide sensitivity to new physics, particularly in the high-energy regime. [...]
