In-Medium Effective Pion Mass from Heavy-Baryon Chiral Perturbation Theory
Tae-Sun Park, Hong Jung, Dong-Pil Min
Using heavy-baryon chiral perturbation theory, we have calculated all the diagrams up to two-loop order which contribute to the S-wave pion self-energy in symmetric nuclear matter.…
In-Medium Effective Axial-Vector Coupling Constant
Tae-Sun Park, Hong Jung, Dong-Pil Min
The axial-vector coupling constant in nuclear medium is systematically studied using chiral perturbation theory. For normal nuclear matter, the first non-trivial corrections are es…
Implications of Recent Data on Non-mesonic Decay of Light Lambda-hypernuclei
Namyoung Lee, Hong Jung, Dongwoo Cha
We analyze the recent data on the non-mesonic decays of light Lambda-hypernuclei up to ^12_Lambda C using the phenomenological model of Block and Dalitz. Fitting the spin-isospin d…
Kaon-Nucleon Scattering from Chiral Lagrangians
Chang-Hwan Lee, Hong Jung, Dong-Pil Min +1
The s-wave scattering amplitude is computed up to one-loop order corresponding to next-to-next-to-leading order (or NLO in short) with a heavy-baryon effective chira…
