Search for the decay D^0 → γγ and measurement of the branching fraction for D^0 → π^0π^0 [PDF]

open access: yes, 2012
We search for the rare decay of the D^0 meson to two photons, D^0→γγ, and present a measurement of the branching fraction for a D^0 meson decaying to two neutral pions, B(D^0→π^0π^0).

Radiative transition of negative to positive parity nucleon

open access: yes, 2015
We investigate the $N^{\ast}(1535)\rightarrow N\gamma$ transition in the framework of light cone QCD sum rules. In particular, using the most general form of the interpolating current for the nucleon as well as the distribution amplitudes of the photon ...

Observation of the decay B s 0 → K 0 p p ¯ $$ {B}_s^0\to {K}^0p\overline{p} $$ and measurement of the B s 0 → K 0 p p ¯ $$ {B}_{(s)}^0\to {K}^0p\overline{p} $$ branching fractions

open access: yesJournal of High Energy Physics
A study of the charmless baryonic decays B s 0 → K 0 p p ¯ $$ {B}_{(s)}^0\to {K}^0p\overline{p} $$ is presented, where B s 0 $$ {B}_{(s)}^0 $$ denotes either a B 0 or a B s 0 $$ {B}_s^0 $$ meson.

Measurement of Γee×Bμμ for ψ(2S) meson

open access: yesPhysics Letters B, 2018
The product of the electronic width of the ψ(2S) meson and the branching fraction of its decay to the muon pair was measured in the e+e−→ψ(2S)→μ+μ− process using nine data sets corresponding to an integrated luminosity of about 6.5 pb−1 collected with ...

Observation of ψ(3686) → Ξ − K S 0 Ω ¯ + $$ {\Xi}^{-}{K}_S^0{\overline{\varOmega}}^{+} $$ + c.c.

open access: yesJournal of High Energy Physics
Using a sample of (2.712 ± 0.014) × 109 ψ(3686) events collected with the BESIII detector at the electron positron collider BEPCII, the decay ψ(3686) → Ξ − K S 0 Ω ¯ + $$ {\Xi}^{-}{K}_S^0{\overline{\varOmega}}^{+} $$ + c.c. is observed for the first time,
