A Lagrangian for the Chiral (1/2,0) + (0,1/2) Quartet Nucleon Resonances
V. Dmitrasinovic, A. Hosaka, K. Nagata
We study the nucleon and three N* resonances' properties in an effective linear realization chiral SU_L(2) x SU_R(2) and U_A(1) symmetric Lagrangian. We place the nucleon fields in…
Nucleon axial couplings and [(1/2,0) + (0,1/2)]-[(1,1/2) + (1/2,1)] chiral multiplet mixing
V. Dmitrasinovic, A. Hosaka, K. Nagata
Three-quark nucleon interpolating fields in QCD have well-defined SU_L(2) x SU_R(2) and U_A(1) chiral transformation properties. Mixing of the [(1,1/2) + (1/2,1)] chiral multiplet…
Wilson fermions with imaginary chemical potential
Keitaro Nagata, Atsushi Nakamura, Yoshiyuki Nakagawa +3
We study the phase structure of imaginary chemical potential. We calculate the Polyakov loop using clover-improved Wilson action and renormalization improved gauge action. We obtai…
On the two-boson exchange corrections to parity-violating elastic electron-proton scattering
Hai Qing Zhou, Chung Wen Kao, Shin Nan Yang +1
The details of the calculation of the two-boson exchange effects in the parity-violating elastic scattering within a simple hadronic model, including both the nucleon and $Δ(1…
The Two-Boson-Exchange Correction to Parity-Violating Elastic Electron-Proton Scattering
Shin Nan Yang, Keitaro Nagata, Hai Qing Zhou +1
We calculate the two-boson-exchange (TBE) corrections to the parity-violating asymmetry of the elastic electron-proton scattering in a simple hadronic model including the nucleon a…
