Derivation of effective field theories [PDF]
A general self-consistency approach allows a thorough treatment of the corrections to the mean-field approximation (MFA). The natural extension of standard MFA with the help of a cumulant expansion leads to a new point of view on the effective field theories. The proposed approach can be used for a systematic treatment of fluctuation effects of various

Nuclear currents in chiral effective field theory [PDF]
In this article, we review the status of the calculation of nuclear currents within chiral effective field theory. After formal discussion of the unitary transformation technique and its application to nuclear currents we give all available expressions ...

Effective Beta-Functions for Effective Field Theory
We consider the problem of determining the beta-functions for any reduced effective field theory. Even though not all the Green's functions of a reduced effective field theory are renormalizable, unlike the full effective field theory, certain effective ...

ΛΛ6He in cluster effective field theory
The bound state of ΛΛ6He is studied as a three-body (ΛΛα) system in a cluster effective field theory at leading order. We find that the system exhibits the limit cycle that is associated with the formation of bound states called the Efimov states.

Hyperon–nucleon interaction within chiral effective field theory revisited [PDF]
The $$\varLambda N$$ Λ N and $$\varSigma N$$ Σ N interactions are considered at next-to-leading order in SU(3) chiral effective field theory. Different options for the low-energy constants that determine the strength of the contact interactions are ...

Effective Field Theory for Nuclear Physics [PDF]
I summarize the motivation for the effective field theory approach to nuclear physics, and highlight some of its recent accomplishments. The results are compared with those computed in potential models.Comment: Talk delivered at Baryons '98, Bonn, Sept ...

Halo Effective Field Theory of 6He
6He has a cluster structure with a tight 4He (α) core surrounded by two loosely bound neutrons (n) making it a halo nucleus. The leading-order (LO) Halo Effective Field Theory (EFT) [1, 2] calculations using momentum-space Faddeev equations pertinent to ...

Constraining the Speed of Sound inside Neutron Stars with Chiral Effective Field Theory Interactions and Observations [PDF]
The dense matter equation of state (EOS) determines neutron star (NS) structure but can be calculated reliably only up to one to two times the nuclear saturation density, using accurate many-body methods that employ nuclear interactions from chiral ...
