Small-$ x $ evolution of gluon fields from incoherent $ \mathrm{J}/\psi $ photoproduction in ultraperipheral PbPb collisions
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. [...]

Search for the associated production of a Higgs boson with a charm quark in the diphoton decay channel in pp collisions at $ \sqrt{s}= $ 13 TeV
This paper presents the first search for the associated production of a Higgs boson with a charm quark ($ \mathrm{c}\mathrm{H} $), with the Higgs boson decaying to two photons. [...]

Search for new physics in jet scaling patterns of multilepton events at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A first search for beyond the standard model physics in jet scaling patterns of multilepton events is presented, using a data sample corresponding to an integrated luminosity of 138 fb$ ^{-1} $ of 13 TeV proton-proton collisions recorded by the CMS detector at the LHC. [...]

Observation of the charged-particle multiplicity dependence of $ \sigma_{\psi(2\text{S})} /\sigma_{\mathrm{J}/\psi} $ in pPb collisions at 8.16 TeV
Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadron collisions. [...]

Development of systematic uncertainty-aware neural network trainings for binned-likelihood analyses at the LHC / CMS Collaboration
We propose a neural network training method capable of accounting for the effects of systematic variations of the data model in the training process and describe its extension towards neural network multiclass classification. [...]
