Determination of the parton distribution functions of the proton using diverse ATLAS data from $pp$ collisions at $s = 7$ , 8 and 13 TeV

ATLAS Collaboration

This paper presents an analysis at next-to-next-to-leading order in the theory of quantum chromodynamics for the determination of a new set of proton parton distribution functions…

A search for an unexpected asymmetry in the production of $e^{+} μ^{-}$ and $e^{-} μ^{+}$ pairs in proton-proton collisions recorded by the ATLAS detector at $s = 13$ TeV

ATLAS Collaboration

This search, a type not previously performed at ATLAS, uses a comparison of the production cross sections for $e^{+} μ^{-}$ and $e^{-} μ^{+}$ pairs to constrain physics processes beyond th…

Number of $J/ ψ$ events at BESIII

BESIII Collaboration

Using inclusive decays of the $J/ ψ$ , a precise determination of the number of $J/ ψ$ events collected with the BESIII detector is performed. For the two data sets taken in 2…

Observation of $J / ψ$ decays to $e^{+} e^{-} e^{+} e^{-}$ and $e^{+} e^{-} μ^{+} μ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +543

Using a data sample of $4.481 \times 1 0^{8} ψ^{'}$ events collected with the BESIII detector, we report the first observation of the four-lepton-decays $J / ψ \to e^{+} e^{-} e^{+} e^{-}$ and $J…

First Measurement of the Absolute Branching Fraction of $Λ \to p μ^{-} ν ˉ_{μ}$

M. Ablikim, M. N. Achasov, P. Adlarson +504

The absolute branching fraction of $Λ \to p μ^{-} ν ˉ_{μ}$ is reported for the first time based on an $e^{+} e^{-}$ annihilation sample of ten billion $J / ψ$ events collected with the BESII…

Measurement of the production cross section of pairs of isolated photons in $pp$ collisions at 13 TeV with the ATLAS detector

ATLAS Collaboration

A measurement of prompt photon-pair production in proton-proton collisions at $s = 13$ TeV is presented. The data were recorded by the ATLAS detector at the LHC with an integr…
