Hadroquarkonium from lattice QCD
(American Physical SocietyPhyscial Review D, 2017-04-03)
he hadroquarkonium picture [S. Dubynskiy and M. B. Voloshin, Phys. Lett. B 666, 344 (2008)] provides one possible interpretation for the pentaquark candidates with hidden charm, recently reported by the LHCb Collaboration, ...
Impact of dynamical charm quarks
(Proceedings of ScienceProceedings of Sciencehttps://pos.sissa.it/256/126/, 2017-01-17)
We compute and compare the continuum limits of several quantities in QCD with and without a dynamical charm quark. We consider both low energy quantities, like the hadronic scales r0 and t 0 , and high energy quantities, ...
