Exclusive photoproduction of $π^{0}$ up to large values of Mandelstam variables $s, t$ and $u$ with CLAS

M. C. Kunkel, 32, 18 M. J. Amaryan +156

Exclusive photoproduction cross sections have been measured for the process $γ p \to p π^{0} (e^{+} e^{-} (γ))$ with the Dalitz decay final state using tagged photon energies in the r…

Observation of $e^{+} e^{-} \to ϕ χ_{c 1}$ and $ϕ χ_{c 2}$ at $s$ =4.600 GeV

M. Ablikim, M. N. Achasov, S. Ahmed +427

Using a data sample collected with the BESIII detector operating at the BEPCII storage ring at a center-of-mass energy of $s = 4.600$ GeV, we search for the production of $e^{…

Branching fraction measurement of $J / ψ \to K_{S} K_{L}$ and search for $J / ψ \to K_{S} K_{S}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +441

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the BEPCII collider, we study the decays of $J / ψ \to K_{S} K_{L}$ and $K_{S} K_{S}$ . The br…

Measurement of the multi-TeV neutrino cross section with IceCube using Earth absorption

IceCube Collaboration, M. G. Aartsen, M. Ackermann +314

Neutrinos interact only very weakly, so they are extremely penetrating. However, the theoretical neutrino-nucleon interaction cross section rises with energy such that, at energies…
