The average total energy as well as its hadronic and electromagnetic components are measured with the CMS detector at pseudorapidities in proton-proton collisions at a centre-of-mass energy . The results are presented as a function of the charged particle multiplicity in the region . This measurement is sensitive to correlations induced by the underlying event structure over a very wide pseudorapidity region. The predictions of Monte Carlo event generators commonly used in collider experiments and ultra-high energy cosmic ray physics are compared to the data. All generators considered overestimate the fraction of energy going into hadrons.

A search for collective effects inside jets produced in proton-proton collisions is performed via correlation measurements of charged particles using the CMS detector at the CERN LHC. The analysis uses data collected at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 138  fb^{-1}. Jets are reconstructed with the anti-k_{T} algorithm with a distance parameter of 0.

Article Synopsis
  • - This Letter discusses the measurement of ridge yields from charged hadron angular correlations in proton-proton collisions at a high energy of 13 TeV, specifically within certain pseudorapidity and transverse momentum ranges.
  • - The research extends ridge yield measurements to low charged-particle multiplicity regions, where typically a strong interacting medium is not expected to form during collisions.
  • - Findings indicate that ridge yields in pp collisions are significantly higher than those observed in e^{+}e^{-} collisions, suggesting that processes in e^{+}e^{-} annihilations do not significantly influence long-range correlations in proton-proton interactions.

Article Synopsis
  • - The study investigates the strange quark content of protons by measuring the production cross section of W bosons and charm quarks in proton-proton collisions at 13 TeV, using data from the CMS detector at the LHC.
  • - W bosons are identified through their decays into leptons (electrons or muons) and neutrinos, while charm quarks are tagged by detecting muons or secondary vertices in jets.
  • - The measurements, which reach a precision of 1%, include both inclusive and differential analyses based on the transverse momentum and pseudorapidity of the leptons, and the results are compared with advanced theoretical predictions in quantum chromodynamics.
