Search for $D^{0} \to γ γ$ and improved measurement of the branching fraction for $D^{0} \to π^{0} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +412

Using $2.92$ fb $^{- 1}$ of electron-positron annihilation data collected at $s = 3.773$ ~GeV with the BESIII detector, we report the results of a search for the flavor-changin…

Equivalence of open/closed strings

Peng Wang, Houwen Wu, Haitang Yang

In this paper, we prove that the open and closed strings are $O (D, D)$ equivalent. The equivalence requires an AdS geometry near the boundaries. The $O (D, D)$ invariance is introduce…

Observation of the electromagnetic doubly OZI-suppressed decay $J / ψ \to ϕ π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +411

Using a sample of $1.31$ billion $J / ψ$ events accumulated with the BESIII detector at the BEPCII collider, we report the observation of the decay $J / ψ \to ϕ π^{0}$ , which is…

Measurement of the proton form factor by studying $e^{+} e^{-} \to p p ˉ$

M. Ablikim, M. N. Achasov, X. C. Ai +409

Using data samples collected with the BESIII detector at the BEPCII collider, we measure the Born cross section of $e^{+} e^{-} \to p p ˉ$ at 12 center-of-mass energies fr…

Measurement of $B (ψ (3770) \to γ χ_{c 1})$ and search for $ψ (3770) \to γ χ_{c 2}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +411

We report a measurement of the branching fraction of $ψ (3770) \to γ χ_{c 1}$ and search for the transition $ψ (3770) \to γ χ_{c 2}$ based on 2.92~fb $^{- 1}$ of $e^{+} e^{-}$ data accumul…

BESIII Collaboration, M. Ablikim, M. N. Achasov +411

Using a sample of $1.06\times10^8\ \psip$ events produced in $e^{+} e^{-}$ collisions at $s$ = 3.686 GeV and collected with the BESIII detector at the BEPCII collider, we present…
