Lattice QCD constraints on pion electroproduction off a nucleon
Yu Zhuge, Zhan-Wei Liu, Derek B. Leinweber +1
Very recently, a lattice QCD collaboration has explored threshold pion electroproduction near the physical pion mass and has simulated the relevant multipole amplitudes. Different…
Pion photoproduction of nucleon excited states with Hamiltonian effective field theory
Yu Zhuge, Dan Guo, Zhan-Wei Liu +2
Over the past few years, Hamiltonian effective field theory has been successfully applied to studies of nucleon and hyperon excited states. By discretizing the Hamiltonian in a fin…
Electromagnetic probes revealing the inner structure of the
Ping Chen, Zi-Le Zhang, Yu Zhuge
The , an open-charm baryon discovered in 2006, has sparked interest due to its ``low mass puzzle'', paralleling the in the charmoniumlike sector. Both states…
Chiral extrapolation of the doubly charmed baryons magnetic properties
Jiong-Jiong Liu, Zhan-Wei Liu, Xiu-Lei Ren +1
The magnetic moments, magnetic form factors, and transition magnetic form factors of doubly charmed baryons are studied within heavy baryon chiral perturbation theory. We regulate…
Pion photoproduction of nucleon excited states with Hamiltonian effective field theory
Yu Zhuge, Zhan-Wei Liu, Derek B. Leinweber +1
We refine our previous calculation of multipole amplitude for pion photoproduction process, . The treatment of final-state interactions is based upon an…
