Shallow states from an EFT analysis of scattering on the lattice
Michael Abolnikov, Lu Meng, Vadim Baru +3
We present an effective field theory (EFT) framework for coupled-channel scattering, applying it to recent lattice QCD results by Alexandrou et al. [Phys. Rev…
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…
Role of left-hand cut contributions on pole extractions from lattice data: Case study for
Meng-Lin Du, Arseniy Filin, Vadim Baru +7
We discuss recent lattice data for the state to stress, for the first time, a potentially strong impact of left-hand cuts from the one-pion exchange on the pole ex…
On the emergence of heavy quark spin symmetry breaking in heavy quarkonium decays
V. Baru, E. Epelbaum, A. A. Filin +2
Heavy-quark spin symmetry (HQSS) implies that in the direct decay of a heavy quarkonium with spin , only lower lying heavy quarkonia with the same spin can be produced. Howe…
Is a molecular partner of and states?
V. Baru, E. Epelbaum, A. A. Filin +2
We perform an effective-field-theory-based coupled-channel analysis of the recent BES III data on the annihilation into the final state in a…
Coupled-channel approach to including three-body effects
Meng-Lin Du, Vadim Baru, Xiang-Kun Dong +6
A coupled-channel approach is applied to the charged tetraquark state recently discovered by the LHCb Collaboration. The parameters of the interaction are fixed by a fit…
Effective range expansion for narrow near-threshold resonances
Vadim Baru, Xiang-Kun Dong, Meng-Lin Du +6
We discuss some general features of the effective range expansion, the content of its parameters with respect to the nature of the pertinent near-threshold states and the necessary…
Insights into and from dipion transitions from
V. Baru, E. Epelbaum, A. A. Filin +4
The dipion transitions () are studied in the framework of a unitary and analytic coupled-channel formalism previously developed for analysing expe…
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…
