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 ...
Measurements of the absolute branching fractions and CP asymmetries for D+ -> (KS,LK+)-K-0 (pi(0))
(2019)
Using e(+)e(-) collision data corresponding to an integrated luminosity of 2.93 fb(-1) taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions B(D+ -> (KSK+)-K-0) ...
Measurement of the absolute branching fractions of Lambda(+)(c) -> Lambda eta pi(+) and Sigma(1385) (+) eta
(2019)
We study the decays Lambda(+)(c) -> Lambda eta pi(+) and Sigma(1385)(+)eta based on Lambda(+)(c)(Lambda) over bar (c) pairs produced in e(+)e(-) collisions at a center-of-mass energy of root s = 4.6 GeV, corresponding to ...
Precision measurement of the e(+)e(-) -> lambda(+)(c)(lambda)over-bar(c)(-) cross section near threshold
(2018)
The cross section of the e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c) process is measured with unprecedented precision using data collected with the BESIII detector at root s = 4574.5, 4580.0, 4590.0 and 4599.5 MeV. ...
Determination of the spin and parity of the z(c)(3900)
(2017)
The spin and parity of the Z(c)(3900)(+/-) state are determined to be J(P) = 1(+) with a statistical significance larger than 7 sigma over other quantum numbers in a partial wave analysis of the process e(+)e(-) -> pi(+)pi(-) ...
Improved measurements of branching fractions for eta(c) -> phi phi and omega phi
(2017)
Using (223.7 +/- 1.4) x 10(6) J / Psi events accumulated with the BESIII detector, we study eta(c) decays to phi phi and omega phi final states. The branching fraction of n(c) -> phi phi is measured to be Br(eta(c) -> phi ...
Search for the radiative leptonic decay D+ -> gamma e (+) nu(e)
(2017)
Using an electron-positron collision data sample of 2.93 fb(-1) collected at a center-of-mass energy of root s = 3.773 GeV with the BESIII detector, we present the first search for the radiative leptonic decay D+ -> gamma ...
Topological cell clustering in the ATLAS calorimeters and its performance in LHC Run 1
(2017)
The reconstruction of the signal from hadrons and jets emerging from the proton-proton collisions at the Large Hadron Collider (LHC) and entering the ATLAS calorimeters is based on a three-dimensional topological clustering ...

Measurement of the charge asymmetry in top quark pair production in pp collisions at √s = 7 TeV using the ATLAS detector
(2012)
A measurement of the top-antitop production charge asymmetry AC is presented using data corresponding to an integrated luminosity of 1.04 fb−1 of pp collisions at √s = 7 TeV collected by the ATLAS detector at the LHC. ...
