Rare and forbidden decays
/ Wang, Zhangqier (MIT)
/ATLAS and CMS Collaborations
Recent measurements of rare decays involving the b-flavor changing neutral current at the CMS and ATLAS experiments are presented. The full set of optimized CP-averaged observables is measured in the angular analysis of the decay ${\mathrm{B}^0} \to \mathrm{K^{\ast 0}(892)} \mu^+\mu^-$ using CMS Run 2 data. [...]

Ricerche di nuova fisica con oggetti pesanti ad alto boost di Lorentz in eventi con jet
/ Favilla, Leonardo (INFN, Naples)
/CMS Collaboration
Le ricerche di nuova fisica nel regime con un elevato boost di Lorentz sono una parte cruciale del programma di fisica di LHC, in quanto potrebbero rivelare la presenza di nuove risonanze pesanti, previste da modelli di fisica oltre il Modello Standard a masse elevate. Nella collaborazione CMS, numerosi algoritmi di boosted-jet tagging sono stati sviluppati per identificare jet adronici che originano appunto dal decadimento di particelle del Modello Standard come quark top, bosoni di Higgs o bosoni vettori, e impiegati in una vasta gamma di analisi.

Recent results in hadron spectroscopy from CMS
/ Mastrapasqua, Vincenzo (INFN, Bari ; Bari U.)
/CMS Collaboration
The present report summarizes recent results on the heavy flavor spectroscopy at the CMS experiment obtained using data collected at the Large Hadron Collider during the 2015-2018 data taking with proton-proton collisions at centre-of-mass energy of 13 TeV the results range from the observation of new structures in the di-charmonium mass spectrum to the observation of new decay modes of beauty baryons such as $\Xi_b^-$ and $\Lambda_b^0$..

Higgs boson cross section and coupling measurements at CMS
/ Jan Lukas Spah
/CMS Collaboration
This report discusses recent measurements of the couplings of the Higgs boson, as well as its inclusive and fiducial production cross sections, by the CMS experiment with data collected at the centre-of-mass energies of $13~\mathrm{TeV}$ and $13.6~\mathrm{TeV}$.
The proceeding presents searches for $W^{\pm}H(b\overline{b})$ and $W^{\pm}W^{\pm}H(b\overline{b})$ production through vector-boson scattering and the measurement of $t\overline{t}H(b\overline{b})$ as well as the search for $tH(b\overline{b})$ production using $138~\mathrm{fb}^{-1}$ of data collected at $\sqrt{s} = 13~\mathrm{TeV}$.
Additionally, the measurements of Higgs boson production in the four-lepton and diphoton final states with data taken in 2022 at $\sqrt{s} = 13.6~\mathrm{TeV}$, corresponding to $34.7~\mathrm{fb}^{-1}$, are discussed.
The results agree with the standard model predictions..

Experimental overview of BSM searches (including resonant HH production)
/ Soffi, Livia (INFN, Rome)
/ATLAS, CMS and LHCB Collaborations
This document summarizes recent results from ATLAS and CMS collaborations in searches for physics Beyond the Standard Model (BSM) using data from LHC Runs 2 and 3. It focuses on key BSM scenarios, including extended Higgs sectors, supersymmetry, heavy fermions, and the two-Higgs-doublet model with an additional pseudoscalar. [...]
