Source: Physical Review D. 2017. Vol. 96, № 1. P. 012005-1-012005-8
Type: статьи в журналах
Date: 2017
Description: Based on a sample of 1.31 billion J/ψ events collected with the BESIII detector, we report the study of the doubly radiative decay η′→γγπ0 for the first time, where the η′ meson is produced via the J/ ... More

Type: статьи в журналах
Date: 2016
Description: A search for the decays of the Higgs and Z bosons to a ϕ meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of 2.7  fb−1 collected at s√=13  TeV ... More

Type: статьи в журналах
Date: 2015
Description: We study D+s decays to final states involving the η with a 482 pb−1 data sample collected at √s = 4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractionsB(D+s →η ... More

Type: статьи в журналах
Date: 2014
Description: A search for excited states of the Bf meson is performed using 4.9 fb-1 of 7 TeVand 19.2 fb-1 of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is observed through i ... More
