Observation of the Charged-Particle Multiplicity Dependence of 𝜎_{𝜓⁡(2⁢𝑆)}/𝜎_𝐽/𝜓 in 𝑝-Pb Collisions at 8.16 TeV See

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. Here, the cross section ratio of excited (𝜓⁡(2⁢𝑆)) and ground state (𝐽/𝜓) vector...

Search for central exclusive production of top quark pairs in proton-proton collisions at √𝒔 = 13 TeV with tagged protons See

A search for the central exclusive production of top quark-antiquark pairs (tt̅) is performed for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 29.4 fb⁻¹....

Re-evaluating the nature of Euroscepticism in border regions: Narratives of Europe in a European election year (Deliverable 3.2: Report on the results of interviews and focus groups) See

In this report, we present a narrative analysis of our original politician interview and citizen focus group data to investigate how borders are featured and narrated in European election campaigns, and how border region residents respond to border narratives in the broader frame o...

Search for heavy neutral leptons in final states with electrons, muons, and hadronically decaying tau leptons in proton-proton collisions at √𝒔 = 13 TeV See

A search for heavy neutral leptons (HNLs) of Majorana or Dirac type using proton-proton collision data at √𝒔 = 13 TeV is presented. The data were collected by the CMS experiment at the CERN LHC and correspond to an integrated luminosity of 138 fb⁻¹. Events with thre...

A search for long-lived heavy neutrinos (N) in the decays of B mesons produced in proton-proton collisions at √𝒔 = 13 TeV is presented. The data sample corresponds to an integrated luminosity of 41.6 fb⁻¹ collected in 2018 by the CMS experiment at the CERN LHC, usin...

Observation of Λ Hyperon Local Polarization in 𝑝Pb Collisions at √𝒔_NN = 8.16 TeV See

The polarization of the Λ and ¯Λ hyperons along the beam direction has been measured in proton-lead (𝑝-Pb) collisions at a center-of-mass energy per nucleon pair of 8.16 TeV. The data were obtained with the CMS detector at the LHC and correspond to an integrated luminosi...

Measurement of inclusive and differential cross sections of single top quark production in association with a W boson in proton-proton collisions at √𝒔 = 13.6 TeV See

The first measurement of the inclusive and normalised differential cross sections of single top quark production in association with a W boson in proton-proton collisions at a centre-of-mass energy of 13.6 TeV is presented. The data were recorded with the CMS detector at the L...

Search for a heavy resonance decaying into a Z and a Higgs boson in events with an energetic jet and two electrons, two muons, or missing transverse momentum in proton-proton collisions at √𝒔 = 13 TeV See

A search is presented for a heavy resonance decaying into a Z boson and a Higgs (H) boson. The analysis is based on data from proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 138 fb⁻¹, recorded with the CMS ex...
