Lattice results on nucleon/roper properties

摘要：

In this proceeding, I review the attempts to calculate the Nucleon resonance (including Roper as first radially excited state of nucleon and other excited states) using lattice quantum chromodynamics (QCD). The latest preliminary results from Hadron Spectrum Collaboration (HSC) with m_n≈380 MeV are reported. The Sachs electric form factor of the proton and neutron and their transition with the Roper at large Q~2 are also updated in this work.
