Baryon-baryon interactions from Effective Field Theory

open access: yesEPJ Web of Conferences, 2010
I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S = −3 to −4 baryon-baryon systems ...

Non-equilibrium effective field theory and second sound

open access: yesJournal of High Energy Physics, 2021
We investigate the phenomenon of second sound in various states of matter from the perspective of non-equilibrium effective field theory (EFT). In particular, for each state of matter considered, we find that at least two (though sometimes multiple ...

DsixTools 2.0: the effective field theory toolkit

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
DsixTools is a Mathematica package for the handling of the standard model effective field theory (SMEFT) and the low-energy effective field theory (LEFT) with operators up to dimension six, both at the algebraic and numerical level.

Virtual photon effects in D=3 Born-Infeld theory [PDF]

open access: yesNucl.Phys. B530 (1998) 487-500, 1998
One loop effects due to virtual gauge field propagation in 2+1 dimensional Born-Infeld theory are investigated. Although this field theory model is not power counting renormalizable, it can be consistently interpreted as an effective field theory. We derive the one-loop effective action in this framework.

Effective Beta-Functions for Effective Field Theory

open access: yes, 2001
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 ...

The effective field theory treatment of quantum gravity [PDF]

open access: yes, 2012
This is a pedagogical introduction to the treatment of quantum general relativity as an effective field theory. It starts with an overview of the methods of effective field theory and includes an explicit example. Quantum general relativity matches this framework and I discuss gravitational examples as well as the limits of the effective field theory ...

On String Field Theory and Effective Actions [PDF]

open access: yesNucl.Phys. B391 (1993) 229-256, 1992
A truncation of string field theory is compared with the duality invariant effective action of $D=4, N=4$ heterotic strings to cubic order. The three string vertex must satisfy a set of compatibility conditions. Any cyclic three string vertex is compatible with the $D=4, N=4$ effective field theory.

Effective Field Theory for Nuclear Physics [PDF]

open access: yes, 1999
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 ...

ΛΛ6He in cluster effective field theory

open access: yesEPJ Web of Conferences, 2016
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.
