Combined measurement of the higgs boson mass in pp collisions at root s=7 and 8 tev with the atlas and cms experiments
(2015)
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 ...
Search for h(c) -> pi(+)pi(-) J/psi via psi(3686) -> pi(0)pi(+)pi(-) J/psi
(2018)
Using a data sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition h(c)-> pi(+)pi(-) J/psi via psi (3686) -> pi(0)hc. No signals ...
Measurement of the absolute branching fraction of the ınclusive decay lambda(+)(c) -> lambda plus x
(2018)
Based on an e(+)e(-) collision data sample corresponding to an integrated luminosity of 567 pb(-1) taken at the center-of-mass energy of root s = 4.6 GeV with the BESIII detector, we measure the absolute branching fraction ...
Precision study of eta ' -> gamma pi(+) pi(-) decay dynamics
(2018)
Using a low background data sample of 9.7 x 10(5) J/psi -> gamma eta',eta' -> gamma pi(+)pi(-) events, which are 2 orders of magnitude larger than those from the previous experiments, recorded with the BESIII detector at ...
Observation of a(0)(0)(980)-f(0)(980) mixing
(2018)
We report the first observation of a(0)(0)(980)-f(0)(980) mixing in the decays of J/psi -> phi f(0)(980) -> phi a(0)(0)(980) -> phi eta pi(0) and chi(c1) -> a(0)(0)(980)pi(0) -> f(0)(980)pi(0)->pi(+)pi(-)pi(0), using data ...
Luminosity determination in pp collisions at root s=8 TeV using the ATLAS detector at the LHC
(2016)
The luminosity determination for the ATLAS detector at the LHC during pp collisions at root s = 8 TeV in 2012 is presented. The evaluation of the luminosity scale is performed using several luminometers, and comparisons ...
Measurement of the Ds<(+)-> l(+)ve branching fractions and the decay constant fDs+
(2016)
Using 482 pb(-1) of e(+) e(-) collision data collected at a center-of-mass energy of root s = 4.009 GeV with the BESIII detector, we measure the branching fractions of the decays D-s(+) -> u(+)v(u) and D-s(+) -> tau(+)v(tau). ...
Performance of the ATLAS trigger system in 2015
(2017)
During 2015 the ATLAS experiment recorded 3.8 fb(-1) of proton-proton collision data at a centre-of-mass energy of 13 TeV. The ATLAS trigger system is a crucial component of the experiment, responsible for selecting events ...
Study of the decays D+-> eta(('))e(+)nu(e)
(2018)
The charm semileptonic decays D+ -> eta e(+)nu(e) and D+ -> eta'e(+)nu(e) are studied with a sample of e(+)e(-) collision data corresponding to an integrated luminosity of 2.93 fb(-1) collected at root s = 3.773 GeV with ...
Search for a strangeonium-like structure Z(s) decaying into phi pi and a measurement of the cross section e(+)e(-) -> phi pi pi
(2019)
Using a data sample of e(+)e(-) collision data corresponding to an integrated luminosity of 108 pb(-1) collected with the BESIII detector at a center-of-mass energy of 2.125 GeV, we study the process e(+)e(-) -> phi pi pi ...
