Electron-positron bremsstrahlung at ADONE. A new limit for the existence of a heavy electron

TL;DR: In this paper, a new measurement of the cross section for the reaction e+e− → e−e− γ has been performed at the ADONE storage ring, using a wide angle electromagnetic detector together with tagging counters for detecting small-angle electrons.
Journal ArticleDOI

Search for the B s 0 → η ′ ϕ decay

Roel Aaij, +801 more
TL;DR: In this paper, a search for the charmless B0s→η′ϕ decay was performed using pp collision data collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1.
Journal ArticleDOI

Observation of the decay Λ b 0 → ψ(2S)pπ −

Roel Aaij, +868 more
TL;DR: In this paper, the Cabibbo-suppressed decay of the ψ(2S)pπ− decay was observed for the first time using a data sample collected by the LHCb experiment in proton-proton collisions corresponding to 1.0, 2.0 and 1.9 fb−1 of integrated luminosity at centre-of-mass energies of 7, 8 and 13 TeV, respectively.
Journal ArticleDOI

Search for narrow resonances in the mass region 1.45–1.92 GeV, in e+e− annihilation into hadrons

TL;DR: In this article, the authors search for possible narrow resonances produced in the reaction e + e − → hadrons, at Adone, in the mass interval, and obtain an upper limit on the energy integrated resonant cross section of about 6% of the corresponding J/ψ(3.1) value.
