Vector charmonium(-like) states in the energy range of 4.1-4.6 GeV
Xiang-Kun Dong, Vadim Baru, Leon von Detten +5
The spectrum of vector charmonium(-like) states in the 4.1\dash4.6~GeV energy region exhibits a long-standing tension between inclusive and exclusive measurements. While the inclus…

Towards a precision determination of the parameters from data
Yi-Lin Song, Yu Zhang, Vadim Baru +3
In a recent paper, Phys. Rev. Lett. {\bf 126}, 132001 (2021), the LHCb data on the di- production in proton-proton collisions were analysed in a coupled-channel framework bas…

Internal structure of the from its light-quark mass dependence
Michael Abolnikov, Vadim Baru, Evgeny Epelbaum +3
We employ a chiral effective field theory-based approach to connect scattering observables at the physical and variable pion masses accessible in lattice QCD simulations. We…
