Perturbative Pions and the Effective Range Expansion
In this talk the Q counting scheme to implement effective field theory is discussed. It is pointed out that there are two small mass scales in the problem mπ and 1/a with 1/a ≪ mπ. It is argued that while the expansion based on 1/a being small compared to the underlying short distance scales works well, the chiral expansion may not. The coefficients of the effective range expansion are sensitiv...
متن کاملAn Improved Feature Selection Based on Effective Range for Classification
Feature selection is a key issue in the domain of machine learning and related fields. The results of feature selection can directly affect the classifier's classification accuracy and generalization performance. Recently, a statistical feature selection method named effective range based gene selection (ERGS) is proposed. However, ERGS only considers the overlapping area (OA) among effective r...
متن کاملThe phase shift effective range expansion from supersymmetric quantum mechanics
Supersymmetric or Darboux transformations are used to construct local phase equivalent deep and shallow potentials for l 6= 0 partial waves. We associate the value of the orbital angular momentum with the asymptotic form of the potential at infinity which allows us to introduce adequate longdistance transformations. The approach is shown to be effective in getting the correct phase shift effect...
متن کاملAn improved effective potential for electroweak phase transitions
It is shown that improved potentials and corrected mass terms can be introduced by using a quadratic source term in the path integral construction for the effective action. The advantage of doing things this way is that we avoid ever having to deal with complex propagators in the loop expansion. The resulting effective action for electroweak phase transitions is similar to the usual results. PA...
متن کاملSelf-consistently improved finite temperature effective potential for gauge theories.
The finite temperature effective potential of the Abelian Higgs Model is studied using the self-consistent composite operator method, which can be used to sum up the contributions of daisy and superdaisy diagrams. The effect of the momentum dependence of the effective masses is estimated by using a Rayleigh-Ritz variational approximation.
