Study of the $e^{+} e^{-} \to π^{+} π^{-} D_{s}^{+} D_{s}^{-}$ process from $s$ = 4.42 to 4.95 GeV at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +782

Based on $8.5 fb^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we inves…

Search for pairs of muons with small displacements in $pp$ collisions at $s = 13$ TeV with the ATLAS detector

ATLAS Collaboration

A search new phenomena giving rise to pairs of opposite electrically charged muons with impact parameters in the millimetre range is presented, using 139 fb $^{- 1}$ of $\sqrt{s} = 1…

Helicity amplitude analysis of $χ_{c J} \to ϕϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

Using (447.9 $\pm$ 2.3) million $ψ$ (3686) events collected with the BESIII detector, the decays of $χ_{c J} \to ϕϕ$ ( $J$ =0, 1, 2) have been studied via the decay $ψ(3686)\ri…

Observation of $ψ (3770) \to η J / ψ$

BESIII Collaboration

The Born cross section of the process $e^{+} e^{-} \to η J / ψ$ at a center-of-mass energy $s = 3.773 GeV$ is measured to be ( $8.89 \pm 0.88 \pm 0.42$ ) $pb$ , using a data…
