Effective field theory of dissipative fluids
We develop an effective field theory for dissipative fluids which governs the dynamics of long-lived gapless modes associated with conserved quantities.

Baryon-baryon interactions from Effective Field Theory
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 ...

Effective field theory for magnetic compactifications
Magnetic flux plays an important role in compactifications of field and string theories in two ways, it generates a multiplicity of chiral fermion zero modes and it can break supersymmetry. We derive the complete four-dimensional effective action for N $$

Goldstone bosons and fluctuating hydrodynamics with dipole and momentum conservation
We develop a Schwinger-Keldysh effective field theory describing the hydrodynamics of a fluid with conserved charge and dipole moments, together with conserved momentum.

Effective field theories and inflation [PDF]
We investigate the possible influence of very-high-energy physics on inflationary predictions focussing on whether effective field theories can allow effects which are parametrically larger than order H^2/M^2, where M is the scale of heavy physics and H is the Hubble scale at horizon exit.

D-brane effective field theory from string field theory
Open string field theory is considered as a tool for deriving the effective action for the massless or tachyonic fields living on D-branes. Some simple calculations are performed in open bosonic string field theory which validate this approach. The level

An Effective Field Theory for Jet Processes [PDF]
Processes involving narrow jets receive perturbative corrections enhanced by logarithms of the jet opening angle and the ratio of the energies inside and outside the jets.

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.

CP-violating axion interactions in effective field theory
Axions are introduced to explain the observed smallness of the θ ¯ $$ \overline{\theta} $$ term of QCD. Standard Model extensions typically contain new sources of CP violation, for instance to account for the baryon asymmetry of the universe.

Narrow Resonances in Effective Field Theory
We discuss the power counting for effective field theories with narrow resonances near a two-body threshold. Close to threshold, the effective field theory is perturbative and only one combination of coupling constants is fine-tuned.
