Anomalous Contribution

As a first step, a simple and pedagogical recall of the η-η′ system is presented, in which the role of the axial anomaly, related to the heterochiral nature of the multiplet of (pseudo)scalar states, is underlined. As a consequence, η is close to the octet and η′ to the singlet configuration. On the contrary, for vector and tensor states, which belong to homochiral multiplets, no anomalous contribution to masses and mixing is present. Then, the isoscalar physical states are to a very good approximation nonstrange and strange, respectively. Finally, for pseudotensor states, which are part of an heterochiral multiplet (just as pseudoscalar ones), a sizable anomalous term is expected: η2(1645) roughly corresponds to the octet and η2(1870) to the singlet.

Anomalous Contribution

An idea of possible anomalous contribution of nonperturbative origin to the nucleon spin was examined by analyzing data on spin asymmetries in polarized deep inelastic scattering of leptons on nucleons. The region of high Bjorken x was explored. It was shown that experimental data available at present do not exhibit any evidence for this effect.

Anomalous Contribution

We continue to explore the possibility that the graviton in two dimensions is related to a quadratic differential that appears in the anomalous contribution of the gravitational effective action for chiral fermions. A higher dimensional analog of this field might exist as well. We improve the defining action for this diffeomorphism tensor field and establish a principle for how it interacts with other fields and with point particles in any dimension. All interactions are related to the action of the diffeomorphism group. We discuss possible interpretations of this field.

Anomalous Contribution

It is well-known by that by studying the symplectic geometry of the underlying symmetry group, the anomalous contribution to effective actions of many systems may be extracted from the path integral. Using this fact, we are able to construct an effective action for the W2 symmetry corresponding to two interacting bosonic fields in three space-time dimensions. We consider this work to be a precursor to the study of W∞ related actions.
