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)→

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-

Angular analysis of the decay B0→K⁎0μ+μ− from pp collisions at s=8 TeV

open access: yesPhysics Letters B, 2016
The angular distributions and the differential branching fraction of the decay B0→K⁎(892)0μ+μ− are studied using data corresponding to an integrated luminosity of 20.5 fb−1 collected with the CMS detector at the LHC in pp collisions at s=8 TeV. From 1430
