A Model Study of Discrete Scale Invariance and Long-Range Interactions
H. -W. Hammer, R. Higa
We investigate the modification of discrete scale invariance in the bound state spectrum by long-range interactions. This problem is relevant for effective field theory description…
alpha-alpha Scattering in Halo Effective Field Theory
R. Higa, H. -W. Hammer, U. van Kolck
We study the two-alpha-particle (alpha-alpha) system in an Effective Field Theory (EFT) for halo-like systems. We propose a power counting that incorporates the subtle interplay of…
Relativistic two-pion exchange nucleon-nucleon potential: parametrized version
R. Higa, M. R. Robilotta, C. A. da Rocha
The chiral two-pion exchange nucleon-nucleon interaction has nowadays a rather firm conceptual basis, but depends on low-energy constants, which may be extracted from fits to data.…
Low-energy constants and relativity in peripheral nucleon-nucleon scattering
Renato Higa
In our recent works we derived a chiral two-pion exchange nucleon-nucleon potential (TPEP) formulated in a relativistic baryon (RB) framework, expressed in terms of the so…
Three Body Force in Peripheral Scattering
R. Higa, M. R. Robilotta
The exchange of a single pion does not contribute to scattering, due to the isoscalar nature of the target. Therefore peripheral scattering may be used to probe existing…
