Search for new Higgs bosons via same-sign top quark pair production in association with a jet in proton-proton collisions at s=13TeV
(2024)Physics Letters BA search is presented for new Higgs bosons in proton-proton (pp) collision events in which a same-sign top quark pair is produced in association with a jet, via the pp→tH/A→ttc‾ and pp→tH/A→ttu‾ processes. Here, H and A represent the extra scalar and pseudoscalar boson, respectively, of the second Higgs doublet in the generalized two-Higgs-doublet model (g2HDM). The search is based on pp collision data collected at a center-of-mass energy ...Journal Article -
Measurements of azimuthal anisotropy of nonprompt D⁰ mesons in PbPb collisions at √sNN = 5.02TeV
(2024)Physics Letters BMeasurements of the elliptic (v₂) and triangular (v₃) azimuthal anisotropy coefficients are presented for Image 1 mesons produced in Image 2 hadron decays (nonprompt Image 1 mesons) in lead-lead collisions at √sNN = 5.02TeV. The results are compared with previously published charm meson anisotropies measured using prompt Image 1 mesons. The data were collected with the CMS detector in 2018 with an integrated luminosity of 0.58nb⁻¹. Azimuthal ...Journal Article -
Two-particle Bose-Einstein correlations and their Lévy parameters in PbPb collisions at √sNN = 5.02 TeV
(2024)Physical Review CTwo-particle Bose–Einstein momentum correlation functions are studied for charged-hadron pairs in lead-lead collisions at a center-of-mass energy per nucleon pair of √sNN = 5.02 TeV. The data sample, containing 4.27 × 10⁹ minimum bias events corresponding to an integrated luminosity of 0.607 nb⁻¹, was collected by the CMS experiment in 2018. The experimental results are discussed in terms of a Lévy-type source distribution. The parameters ...Journal Article -

Search for exotic decays of the Higgs boson to a pair of pseudoscalars in the μμbb and ττbb final states
(2024)The European Physical Journal CA search for exotic decays of the Higgs boson (H) with a mass of 125 GeV to a pair of light pseudoscalars a1 is performed in final states where one pseudoscalar decays to two b quarks and the other to a pair of muons or τ leptons. A data sample of proton–proton collisions at √s = 13 TeV cor- responding to an integrated luminosity of 138 fb^−1 recorded with the CMS detector is analyzed. No statistically signifi- cant excess is ...Journal Article -
Search for neutral MSSM Higgs bosons at LEP
(2006)The European Physical Journal CThe four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric standard model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of ...Journal Article
