Search for long-lived particles using displaced vertices with low-momentum tracks in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for long-lived particles using final states including a displaced vertex with low-momentum tracks, large missing transverse momentum, and a jet from initial-state radiatio…
Search for light pseudoscalar boson pairs produced from Higgs boson decays using the 4 and 22 final states in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for a pair of light pseudoscalar bosons (a) produced in the decay of the 125 GeV Higgs boson is presented. The analysis examines decay modes where one a decays int…
Reconstruction of overlapping electromagnetic showers in calorimeters using Transformers
Yuliia Maidannyk, Fabrice Couderc, Julie Malclès +1
Accurate clustering of electromagnetic energy deposits is essential for reconstructing photons and electrons in modern hadron collider experiments, where boosted topologies and pil…
Observation of coherent (1020) meson photoproduction in ultraperipheral PbPb collisions at = 5.36 TeV
CMS Collaboration
The first observation of coherent (1020) meson photoproduction off heavy nuclei is presented using ultraperipheral lead-lead collisions at a center-of-mass energy per nucleon p…
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 towa…
Observation of the charged-particle multiplicity dependence of in pPb collisions at 8.16 TeV
CMS Collaboration
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 hadro…
