The Baryon-Baryon Interaction in the Large- Limit
Thomas Vonk, Ulf-G. Meißner
We analyze the large- structure of the baryon-baryon potential derived in the framework of SU(3) chiral perturbation theory up to next-to-leading order including contact inter…
Pion axioproduction: The Delta resonance contribution
Thomas Vonk, Feng-Kun Guo, Ulf-G. Meißner
The process of pion axioproduction, , with an intermediate resonance is analyzed using baryon chiral parturbation theory. The resonance is included in two ways: Fi…
Axions in Baryon Chiral Perturbation Theory
Thomas Vonk
I give an overview of recent developments in the study of the coupling of the QCD axion to nucleons and other octet baryons. I demonstrate how axions can be included into heavy bar…
Alpha-alpha scattering in the Multiverse
Serdar Elhatisari, Timo A. Lähde, Dean Lee +2
We investigate the phase shifts of low-energy alpha-alpha scattering under variations of the fundamental parameters of the Standard Model, namely the light quark mass, the electrom…
The axion-baryon coupling in SU(3) heavy baryon chiral perturbation theory
Thomas Vonk, Feng-Kun Guo, Ulf-G. Meißner
In the past, the axion-nucleon coupling has been calculated in the framework of SU(2) heavy baryon chiral perturbation theory up to third order in the chiral power counting. Here,…
-dependence of light nuclei and nucleosynthesis
Dean Lee, Ulf-G. Meißner, Keith A. Olive +2
We investigate the impact of the QCD vacuum at nonzero on the properties of light nuclei, Big Bang nucleosynthesis, and stellar nucleosynthesis. Our analysis starts with a calc…
QCD -vacuum energy and axion properties
Zhen-Yan Lu, Meng-Lin Du, Feng-Kun Guo +2
At low energies, the strong interaction is governed by the Goldstone bosons associated with the spontaneous chiral symmetry breaking, which can be systematically described by chira…
Precision calculation of the axion-nucleon coupling in chiral perturbation theory
Thomas Vonk, Feng-Kun Guo, Ulf-G. Meißner
We derive the axion-nucleon interaction Lagrangian in heavy baryon chiral perturbation theory up to next-to-next-to-leading order. The effective axion-nucleon coupling is calculate…
Aspects of the QCD -vacuum
Thomas Vonk, Feng-Kun Guo, Ulf-G. Meißner
This paper addresses two aspects concerning the -vacuum of Quantum Chromodynamics. First, large- chiral perturbation theory is used to calculate the first two non-trivial c…
