Study of eta(1475) and X(1835) in radiative J/psi decays to gamma phi
(2018)
The decay J/psi -> gamma gamma phi is studied using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector. Two structures around 1475 MeV/c(2) and 1835 MeV/c(2) are observed in the gamma phi invariant ...
Observation of an excited b-c(+/-) meson state with the atlas detector
(2015)
A search for excited states of the B-c(+/-) meson is performed using 4.9 fb(-1) of 7 TeV and 19.2 fb(-1) of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is observed through its hadronic ...
Search for the rare decay of Psi(3686) -> Lambda+pe(+)e(-) +c.c. at BESIII
(2018)
Based on a data sample of (448.1 +/- 2.9) x 10(6)Psi(3686) decays collected with the BESIII experiment, a search for the flavor changing neutral current transition Psi(3686) -> Lambda(+)(c) pe(+) e(-) + c.c. is performed ...
Search for the rare decays D -> h(h((')))e(+) e(-)
(2018)
We search for rare decays of D mesons to hadrons accompanied by an electron-positron pair (h(h((')))e(+)e(- )),using an e(+)e(-) collision sample corresponding to an integrated luminosity of 2.93 fb(-1) collected with the ...
Dalitz plot analysis of the decay omega -> pi(+) pi(-) pi(0)
(2018)
Using a low-background sample of 2.6 x 10(5) J/psi -> omega eta(omega -> pi(+) pi(-) pi(0), eta -> gamma gamma) events, about 5 times larger statistics than previous experiments, we present a Dalitz plot analysis of the ...
Search for the dimuon decay of the higgs boson in pp collisions at root s=13 tev with the atlas detector
(2017)
A search for the dimuon decay of the Higgs boson was performed using data corresponding to an integrated luminosity of 36.1 fb(-1) collected with the ATLAS detector in pp collisions at root s = 13 TeV at the Large Hadron ...
Measurement of e(+) e(-) -> K+ K- cross section at root s=2.00-3.08 GeV
(2019)
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 ...
Reconstruction of hadronic decay products of tau leptons with the ATLAS experiment
(2016)
This paper presents a new method of reconstructing the individual charged and neutral hadrons in tau decays with the ATLAS detector. The reconstructed hadrons are used to classify the decay mode and to calculate the visible ...
Observation of D-s(+) -> p(n)over-bar and confirmation of its large branching fraction
(2019)
The baryonic decay D-s(+) -> p (n) over bar is observed, and the corresponding branching fraction is measured to be (1.21 +/- 0.10 +/- 0.05) x 10(-3), where the first uncertainty is statistical and second systematic. The ...
Observation of z(c)(3900)(0) in e(+)e(-) -> pi(0)pi(0) j/psi
(2015)
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Z(c)(3900)(0) with a significance of 10.4 sigma. The mass and width are measured to be 3894.8 +/- ...
