N. Krawczyk, B. C. Hiesmayr, J. Chhokar, C. Curceanu, more

Hyperfine Interactions > 2019 > 240 > 1 > 1-5

J-PET is the first positron-emission tomograph (PET) constructed from plastic scintillators. It was optimized for the detection of photons from electron-positron annihilation. Such photons, having an energy of 511 keV, interact with electrons in plastic scintillators predominantly via the Compton effect. Compton scattering is at most probable at an angle orthogonal to the electric field vector of...

Study of the rare decays of B_s⁰ and B⁰ mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector

The ATLAS collaboration, M. Aaboud, G. Aad, B. Abbott, more

Journal of High Energy Physics > 2019 > 2019 > 4 > 1-47

Abstract A study of the decays B_s⁰ → μ⁺μ⁻ and B⁰ → μ⁺μ⁻ has been performed using 26.3 fb⁻¹ of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016. Since the detector resolution in μ⁺μ⁻ invariant mass is comparable to the B_s⁰ -B⁰ mass difference, a single fit determines the signal yields for both decay modes. This results in a measurement of the branching fraction...
