Few-Body Systems and the Pionless Effective Field Theory
نویسنده
چکیده
The pionless effective field theory (EFT) is the appropriate low-energy EFT for short-range interactions that display a large scattering length. It has been successfully applied in atomic, nuclear and particle physics. We give an overview over recent calculations employing the pionless effective field theory and lay emphasis on applications in the threeand four-body sector where the most exciting developments have occurred.

We study the triton and three-nucleon force at lowest chiral order in pionless effective field theory both in the Hamiltonian and Euclidean nuclear lattice formalism. In the case of the Euclidean lattice formalism, we derive the exact few-body worldline amplitudes corresponding to the standard many-body lattice action. This will be useful for setting low-energy coefficients in future nuclear la...

متن کاملRearranging Pionless Effective Field Theory
We point out a redundancy in the operator structure of the pionless effective field theory, EFT(π/), which dramatically simplifies computations. This redundancy is best exploited by using dibaryon fields as fundamental degrees of freedom. In turn, this suggests a new power counting scheme which sums range corrections to all orders. We explore this method with a few simple observables: the deute...
متن کاملElectroweak Processes of the Deuteron in Effective Field Theory
We review our recent calculations of electroweak processes involving the deuteron, based on pionless effective field theory with dibaryon fields. These calculations are concerned with neutron-neutron fusion and np → dγ at BBN energies.
متن کاملPions in the Pionless Effective Field Theory
We show that processes involving pions that remain very near their massshell can be reliably computed in the pionless effective field theory, with the pion integrated in as a heavy field. As an application, we compute the πdeuteron scattering amplitude near threshold to next-to-leading order in the momentum expansion. This amplitude is formally dominated by an infrared logarithm of the form log...
