Superhorizon fluctuations and the cosmic dipole problem

Ge Chen, Chengcheng Han, Linwei Qiu

Recent observations have identified a significant 4.9 $σ$ tension between the cosmic dipole inferred from galaxy number counts and that derived from the Cosmic Microwave Background…

Observation of the decay $ψ (3686) \to Σ^{0} Σ ˉ^{0} ω$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a dataset of $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of the decay $…

Determination of spin and parity of $D_{(s)}^{*}$ mesons

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

The spin and parity of the charmed mesons $D_{s}^{*+}$ , $D^{* 0}$ and $D^{*+}$ are determined for the first time to be $J^{P} = 1^{-}$ with significances greater than 10 $σ$ over other h…
