Precision measurements of branching fractions for $ψ^{'} \to π^{0} J ψ$ and $η J ψ$

M. Ablikim, M. N. Achasov, O. Albayrak +342

We present a precision study of the $\psip\toπ^0 J/ψ$ and $η J / ψ$ decay modes. The measurements are obtained using $106 \times 1 0^{6}$ $ψ^{'}$ events accumulated with the BESIII detector a…

Search for hadronic transition $χ_{c J} \to η_{c} π^{+} π^{-}$ and observation of $χ_{c J} \to K K ˉ π π π$

The BESIII Collaboration, M. Ablikim, M. N. Achasov +339

Hadronic transitions of $χ_{c J} \to η_{c} π^{+} π^{-}$ (J=0, 1, 2) are searched for using a sample of $1.06 \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector at the BE…

First observation of the isospin violating decay $J / ψ \to Λ Σ ˉ^{0} + c . c .$

M. Ablikim, M. N. Achasov, D. J. Ambrose +353

Using a sample of $(225.2 \pm 2.8) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we present results of a study of $J / ψ \to γ Λ Λ ˉ$ and report the first observ…

Observation of two new $N^{*}$ resonances in $ψ (3686) \to p p ˉ π^{0}$

BESIII Collaboration

Based on 106 $\times 1 0^{6} ψ (3686)$ events collected with the BESIII detector at the BEPCII facility, a partial wave analysis of $ψ (3686) \to p p ˉ π^{0}$ is performed. The bra…

First observation of the M1 transition $ψ (3686) \to γ η_{c} (2 S)$

M. Ablikim, M. N. Achasov, D. J. Ambrose +356

Using a sample of 106 million ψ(3686) events collected with the BESIII detector at the BEPCII storage ring, we have made the first measurement of the M1 transition between the radi…

Search for supersymmetry in events with three leptons and missing transverse momentum in sqrt(s) = 7 TeV pp collisions with the ATLAS detector

ATLAS Collaboration

A search for the weak production of charginos and neutralinos into final states with three electrons or muons and missing transverse momentum is presented. The analysis uses 2.06 f…
