Leading order relativistic hyperon-nucleon interactions in chiral effective field theory
Kai-Wen Li, Xiu-Lei Ren, Li-Sheng Geng +1
We apply a recently proposed covariant power counting in nucleon-nucleon interactions to study strangeness interactions in chiral effective field theory. At leading…
Power Counting in Peripheral Partial Waves: The Singlet Channels
M. Pavón Valderrama, M. Sánchez Sánchez, C. -J. Yang +3
We analyze the power counting of the peripheral singlet partial waves in nucleon-nucleon scattering. In agreement with conventional wisdom, we find that pion exchanges are perturba…
Leading order relativistic chiral nucleon-nucleon interaction
Xiu-Lei Ren, Kai-Wen Li, Li-Sheng Geng +3
Motivated by the successes of relativistic theories in studies of atomic/molecular and nuclear systems and the need for a relativistic chiral force in relativistic nuclear structur…
Three-body system of
Bingwei Long
The existence of near-threshold charmed baryon implies that the pion and the lightest, isospin- charmed baryon interact very strongly at extremely low energi…
Cutoff regulators in chiral nuclear effective field theory
Bingwei Long, Ying Mei
Three-dimensional cutoff regulators are frequently employed in multi-nucleon calculations, but they violate chiral symmetry and Lorentz invariance. A cutoff regularization scheme i…
Triangle diagram in heavy-baryon chiral perturbation theory
Songlin Lyu, Bingwei Long
The pion-baryon triangle diagram is inspected for a special kinematic region where the squared momentum transfer is close to : . Inst…
