Search for long-lived heavy neutrinos in the decays of B mesons produced in proton-proton collisions at √s = 13 TeV
Abstract 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, using a dedicated data stream that enhances the number of recorded events containing B mesons.
Search for long-lived particles decaying to final states with a pair of muons in proton-proton collisions at √s = 13.6 TeV
Abstract An inclusive search for long-lived exotic particles (LLPs) decaying to final states with a pair of muons is presented. The search uses data corresponding to an integrated luminosity of 36.6 fb−1 collected by the CMS experiment from the proton-proton collisions at √s = 13.6 TeV in 2022, the first year of Run 3 of the CERN LHC.

Model-independent search for pair production of new bosons decaying into muons in proton-proton collisions at √s = 13 TeV
Abstract The results of a model-independent search for the pair production of new bosons within a mass range of 0.21 < m < 60 GeV, are presented. This study utilizes events with a four-muon final state. We use two data sets, comprising 41.5 fb−1 and 59.7 fb−1 of proton-proton collisions at √s = 13 TeV, recorded in 2017 and 2018 by the CMS experiment at the CERN LHC.
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
Abstract 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 LHC in 2022, and correspond to an integrated luminosity of 34.7 fb⁻¹. The analysed events contain one muon and one electron in the final state.
Observation of nuclear modification of energy-energy correlators inside jets in heavy ion collisions
Abstract 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.
Measurement of the tt̄H and tH production rates in the H → bb̅ decay channel using proton-proton collision data at √s = 13 TeV
An analysis of the production of a Higgs boson (H) in association with a top quark-antiquark pair (tt̄H) or a single top quark (tH) is presented. The Higgs boson decay into a bottom quark-antiquark pair (H → bb̅) is targeted, and three different final states of the top quark decays are considered, defined by the number of leptons (electrons or muons) in the event.

Search for heavy long-lived charged particles with large ionization energy loss in proton-proton collisions at √s = 13 TeV
Abstract A search for heavy, long-lived, charged particles with large ionization energy loss within the silicon tracker of the CMS experiment is presented. A data set of proton-proton collisions at a center of mass energy at √s = 13 TeV, collected in 2017 and 2018 at the CERN LHC, corresponding to an integrated luminosity of 101 fb−1, is used in this analysis. Two different approaches for the search are taken.
Bottom quark energy loss and hadronization with B⁺ and B⁰s nuclear modification factors using pp and PbPb collisions at √sNN = 5.02 TeV
Abstract The production cross sections of B⁰s and B+ mesons are reported in proton-proton (pp) collisions recorded by the CMS experiment at the CERN LHC with a center-of-mass energy of 5.02 TeV. The data sample corresponds to an integrated luminosity of 302 pb−1. The cross sections are based on measurements of the B⁰s → J/ψ(μ+μ−)ϕ(1020)(K+K−) and B+ → J/ψ(μ+μ−)K+ decay channels.

International consensus-based ranking of definitions for poor response to primary total knee arthroplasty: a Delphi study - Archives of Orthopaedic and Trauma Surgery
Abstract This study aimed to rank definitions for measuring poor response one year after TKA, after assessing the face validity and feasibility of existing or newly proposed definitions. An international, three-round, online modified Delphi study was conducted with sixty-nine panelists from twenty-three countries. Definitions were derived from a literature review or were newly proposed by an expert group.
Search for heavy neutral leptons in final states with electrons, muons, and hadronically decaying tau leptons in proton-proton collisions at √ = 13 TeV

In addition, we gratefully acknowledge the computing centres and personnel of the Worldwide LHC Computing Grid and other centres for delivering so effectively the computing infrastructure essential to our analyses.
Exploration of adverse consequences of total knee arthroplasty by patients and knee specialists: a qualitative study
Total knee arthroplasty (TKA) is considered to be a successful and cost-effective intervention for treatment of advanced symptomatic OA [1]. However, despite improvement in knee pain and disability, 15–20% of the patients report being dissatisfied with their prosthetic knee owing to insufficient pain relief, loss of function and limitations in physical functioning [2–5]. To improve the dissatisfaction rate, a clear and valid definition of what a poor outcome after TKA entails is needed.
