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 base…
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…
How does the show up in collisions: dip versus peak
Vadim Baru, Feng-Kun Guo, Christoph Hanhart +1
We demonstrate that the dip observed near the total energy of 3872 MeV in the recent cross section data from the BESIII Collaboration for admits a natural ex…
How many vector charmonium(-like) states sit in the energy range from to GeV?
Leon von Detten, Vadim Baru, Christoph Hanhart +3
In recent years many vector charmonium(-like) states were reported by different electron-positron collider experiments above GeV. However, so far, there not only exists sizab…
Production of the as the spin-2 partner of in collisions
Pan-Pan Shi, Vadim Baru, Feng-Kun Guo +2
In 2021, the Belle collaboration reported the first observation of a new structure in the final state produced in the two-photon fusion process. In the hadronic molecule…
The as a molecule
Leon von Detten, Christoph Hanhart, Vadim Baru
We show that the currently available data are consistent with being a hadronic molecule. By a simultaneous fit to data from $e^+ e^- \rightarrow D^0 D^{* -}…
Implications of spin symmetry for XYZ states
Q. Wang, V. Baru, E. Epelbaum +4
Numerous exotic candidates containing a heavy quark and anti-quark (the so-called states) have been reported since the observation of the in 2003. For these systems…
Remarks on the Heavy-Quark Flavour Symmetry for doubly heavy hadronic molecules
V. Baru, E. Epelbaum, J. Gegelia +3
The possibility for a common effective field theory for hadronic molecules with different heavy-quark flavours is examined critically. It is argued that such a theory does not allo…
Binding energy of the at unphysical pion masses
V. Baru, E. Epelbaum, A. A. Filin +2
Chiral extrapolation of the binding energy is investigated using the modified Weinberg formulation of chiral effective field theory for the scattering. Give…
Remarks on the study of the X(3872) from Effective Field Theory with Pion-Exchange Interaction
V. Baru, E. Epelbaum, A. A. Filin +5
In a recent paper Phys.Rev.Lett. 111, 042002 (2013) (arXiv:1304.0846), the charmonium state X(3872) is studied in the framework of an effective field theory. In that work it is cla…
Quark mass dependence of the X(3872) binding energy
V. Baru, E. Epelbaum, A. A. Filin +3
We explore the quark-mass dependence of the pole position of the X(3872) state within the molecular picture. The calculations are performed within the framework of a nonrelativisti…
Comment on "Possibility of Deeply Bound Hadronic Molecules from Single Pion Exchange"
A. A. Filin, A. Romanov, V. Baru +5
We demonstrate that in calculation, where unitarity constraints are properly imposed, the deeply bound hadronic molecules recently proposed by Close and Downum do not exist.
