Measurement of the inclusive branching fraction for ψ(3686)→KS0+anything

open access: yesPhysics Letters B, 2021
Using 5.9 pb−1 of e+e− annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e+e−→KS0X (where X=anything).

Observation of Ds+ K- and evidence for Ds+ pi- final states in neutral B decays [PDF]

open access: yes, 2002
We report the first observation of a B meson decay that is not accessible by a direct spectator process. The channel B0bar -> Ds+ K- is found in a sample of 85 timse 10^6 B Bbar events, collected with the Belle detector at KEKB, with a branching fraction

Search for the Higgs boson decay to a pair of electrons in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2023
A search is presented for the Higgs boson decay to a pair of electrons (Image 1) in proton-proton collisions at s=13TeV. The data set was collected with the CMS experiment at the LHC between 2016 and 2018, corresponding to an integrated luminosity of ...

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at s√=8 TeV with the ATLAS detector [PDF]

open access: yes, 2014
The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1fb−1 of proton–proton collision data at √s = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is

Measurement of the branching fraction for ψ(3770)→γχc0

open access: yesPhysics Letters B, 2016
By analyzing a data set of 2.92 fb−1 of e+e− collision data taken at s=3.773 GeV and 106.41×106 ψ(3686) decays taken at s=3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ(3770)→

Measurement of branching fractions of J/ψ and ψ(3686) decays to Σ+ and Σ ¯ $$ \overline{\Sigma} $$ −

open access: yesJournal of High Energy Physics, 2021
Using 1310.6 × 106 J/ψ and 448.1 × 106 ψ(3686) events collected with the BESIII detector, the branching fractions of J/ψ decays to Σ+ Σ ¯ $$ \overline{\Sigma} $$ − is measured to be (10.61 ± 0.04 ± 0.36) × 10 −4, which is significantly more precise than ...

Search for the decay h c → π 0 J/ψ

open access: yesJournal of High Energy Physics, 2022
A search for the decay h c → π 0 J/ψ is performed using a sample of hc produced in the reaction e + e − → π + π − h c . The data samples were collected with the BESIII detector at center-of-mass energies between 4.189 and 4.437 GeV, corresponding to a ...

Search for a standard model-like Higgs boson in the μ+μ− and e+e− decay channels at the LHC

open access: yesPhysics Letters B, 2015
A search is presented for a standard model-like Higgs boson decaying to the μ+μ− or e+e− final states based on proton–proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to integrated luminosities of 5.0 fb−1 at a centre-
