Particle production and identification for the T10 secondary beamline of the CERN East Area
/ van Dijk, Maarten (CERN) ; Hayat, Ahsan (CERN) ; Banerjee, Dipanwita (CERN) ; Bernhard, Johannes (CERN) ; Gokturk, Berare (CERN ; Bogazici U.) ; Nevay, Laurie (CERN) ; Petersen, Jorgen (CERN) ; Schwinzerl, Martin (CERN)
The particle composition of the T10 beam line in the renovated East Hall at CERN has been measured using several experimental techniques and detectors: pressure scans on a threshold Cherenkov counter, a lead-glass calorimeter, time-of-flight, and finally using two separate threshold Cherenkov counters.

Observation of orbitally excited $B_{c}^{+}$ states
/ LHCb Collaboration
The observation of a wide peaking structure in the $B_{c}^{+} γ$ mass spectrum is reported using proton-proton collision data collected by the LHCb detector at center-of-mass energies of $7$, $8$ and $13~\text{TeV}$, corresponding to a total integrated luminosity of $9~\text{fb}^{-1}$. [...]

Study of $B_{c}(1P)^{+}$ states in the $B_{c}^{+} \gamma$ mass spectrum
/ LHCb Collaboration
The study of a wide peaking structure in the $B_{c}^{+} γ$ mass spectrum is reported using a data sample of proton-proton collisions collected by the LHCb detector at center-of-mass energies of $7$, $8$ and $13~\text{TeV}$, corresponding to an integrated luminosity of $9~\text{fb}^{-1}$. [...]

(Argonne) et al.
The difference in the proton and neutron separation energies ($\Delta S$) of the weakly bound $^{15}$C ground state is -19.86 MeV, an extreme value. [...]
