Combined effective field theory interpretation of Higgs boson, electroweak vector boson, top quark, and multijet measurements / CMS Collaboration
Constraints on Wilson coefficients (WCs) corresponding to dimension-6 operators of the standard model effective field theory (SMEFT) are determined from a simultaneous fit to seven sets of CMS measurements probing Higgs boson, electroweak vector boson, top quark, and multijet production. [...]

Observation of a pseudoscalar excess at the top quark pair production threshold / CMS Collaboration
A search for resonances in top quark pair ($ \mathrm{t} \overline{\mathrm{t}} $) production in final states with two charged leptons and multiple jets is presented, based on proton-proton collision data collected by the CMS experiment at the CERN LHC at $ \sqrt{s}= $ 13 TeV, corresponding to 138 fb$ ^{-1} $. The analysis explores the invariant mass of the $ \mathrm{t} \overline{\mathrm{t}} $ system and two angular observables that provide direct access to the correlation of top quark and antiquark spins.

Observation of $ \mathrm{W}\mathrm{Z}\gamma $ production and constraints on new physics scenarios in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A measurement of the $ \mathrm{W}\mathrm{Z}\gamma $ triboson production cross section is presented. The analysis is based on a data sample of proton-proton collisions at a center-of-mass energy of $ \sqrt{s}= $ 13 TeV recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 138 fb$ ^{-1} $.

Search for dark matter production in association with a single top quark in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search for the production of a single top quark in association with invisible particles is performed using proton-proton collision data collected with the CMS detector at the LHC at $ \sqrt{s} = $ 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. In this search, a flavor-changing neutral current produces a single top quark or antiquark and an invisible state nonresonantly. [...]

Search for $ t $-channel scalar and vector leptoquark exchange in the high-mass dimuon and dielectron spectra in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search for $ t $-channel exchange of leptoquarks (LQs) is performed in dimuon and dielectron spectra using proton-proton collision data collected at $ \sqrt{s}= $ 13 TeV with the CMS detector at the CERN LHC. [...]

Observation of nuclear modification of energy-energy correlators inside jets in heavy ion collisions / CMS Collaboration
Energy-energy correlators are constructed by averaging the number of charged particle pairs within jets, weighted by the product of their transverse momenta, as a function of the angular separation of the particles within a pair. They are sensitive to a multitude of perturbative and nonperturbative quantum chromodynamics phenomena in high-energy particle collisions. [...]

Search for vector-like leptons with long-lived particle decays in the CMS muon system in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A first search is presented for vector-like leptons (VLLs) decaying into a light long-lived pseudoscalar boson and a standard model $ \tau $ lepton. The pseudoscalar boson is assumed to have a mass of 2 GeV and to decay exclusively into a pair of photons. [...]

Machine Learning (ML) is driving a revolution in the way scientists design, develop, and deploy data-intensive software. However, the adoption of ML presents new challenges for the computing infrastructure, particularly in terms of provisioning and orchestrating access to hardware accelerators for development, testing, and production.

Probing Gluon Fluctuations in Nuclei with the First Energy-Dependent Measurement of Incoherent <math display="inline"><mi>J</mi><mo>/</mo><mi>ψ</mi></math> Photoproduction in Ultraperipheral PbPb Collisions / CMS Collaboration
Incoherent $ \mathrm{J}/\psi $ photoproduction in heavy ion ultraperipheral collisions (UPCs), in which the photon interacts with localized, fluctuating gluonic hotspots rather than the entire nucleus, provides a unique probe of those fluctuations. This study presents the first measurement of the dependence of this photoproduction yield on the photon-nucleon center-of-mass energy ($ W_{\gamma\mathrm{N}} $), using PbPb UPCs at a nucleon-nucleon center-of-mass energy of 5.02 TeV.
