Determination of the number of ψ(3686) events at BESIII
The numbers of psi(3686) events accumulated by the BESIII detector for the data taken during 2009 and 2012 are determined to be (107.0 +/- 0.8)x10(6) and (341.1 +/- 2.1)x10(6), respectively, by counting inclusive hadronic ...
Search for higgs and z boson decays to phi gamma with the atlas detector
A search for the decays of the Higgs and Z bosons to a phi meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of 2.7 fb(-1) collected at root s = 13 TeV with the ATLAS ...
Measurement of e(+) e(-) -> K+ K- cross section at root s=2.00-3.08 GeV
The cross section of the process e(+) e(-) -> K+ K- is measured at a number of center-of-mass energies root s from 2.00 to 3.08 GeV with the BESIII detector at the Beijing Electron Positron Collider (BEPCII). The results ...
Search for heavy resonances decaying into a W or Z boson and a Higgs boson in final states with leptons and b-jets in 36 fb-1 of root s = 13 TeV pp collisions with the ATLAS detector
One correction is noted for the paper. The exclusion limits for the gluon-gluon fusion production of an A boson reported in the conclusions did not correspond to the exclusion plots shown in figure 6a.
Search for Higgs boson pair production in the WW(*)WW(*) decay channel using ATLAS data recorded at s√ = 13 TeV
A search for a pair of neutral, scalar bosons with each decaying into two W bosons is presented using 36.1 fb(-1) of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the ...
Combined measurement of the higgs boson mass in pp collisions at root s=7 and 8 tev with the atlas and cms experiments
A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H -> gamma gamma and H -> ZZ -> 4l decay channels. The results are obtained from ...
Branching fraction measurements of psi (3686) -> gamma chi(cJ)
Using a sample of 106 million psi(3686) decays, the branching fractions of psi(3686) -> gamma chi(c0), psi(3686) -> gamma chi(c1), and psi(3686) -> gamma chi(c2) are measured with improved precision to be (9.389 +/- 0.014 ...
Measurement of the W boson polarisation in t(t)over-bar events from pp collisions at root s = 8 TeV in the lepton + jets channel with ATLAS (vol 77, pg 264, 2018)
This change does not have any impact on the measured helicity fractions, but it changes the obtained limits on the anomalous couplings.
Search for lepton-flavour-violating decays of the Higgs and Z bosons with the ATLAS detector
Direct searches for lepton flavour violation in decays of the Higgs and Z bosons with the ATLAS detector at the LHC are presented. The following three decays are considered: H -> e tau, H -> mu tau, and Z -> mu tau. The ...
