We study chiral SU(N) supersymmetric gauge theories with matter in the antifundamental and antisymmetric representations. For SU(5) with two families, we show how to reproduce the non-perturbatively generated superpotential, and we discuss dynamical supersymmetry breaking purely in terms of the Konishi anomaly. We apply the same technique in general to SU(N) with one family. We also briefly com...

2 and 3-point functions in the ENJL-model 1. Abstract We discuss the extended Nambu-Jona-Lasinio model as a low energy expansion , all two-point functions and an example of a three-point function to all orders in momenta and quark masses. The model is treated at leading level in 1/Nc but otherwise exact. Some comments about the QCD flavour anomaly and Vector Meson Dominance in this class of mod...

We show analytically that the ratio of the norm of sliver states agrees with the ratio of D-brane tensions. We find that the correct ratio appears as a twist anomaly.

Abelian quiver gauge theories provide nonsupersymmetric candidates for the conformality approach to physics beyond the standard model. Written asN = 0, U(N) gauge theories, however, they have mixed U(1)pU(1) 2 q and U(1)pSU(N) 2 q triangle anomalies. It is shown how to construct explicitly a compensatory term ∆Lcomp which restores gauge invariance of Leff = L+∆Lcomp under U(N). It can lead to a...

We investigate a possible explanation for the NuTeV anomaly in terms of a nuclear correction difference between uv and dv distributions. Analyzing deep elastic scattering and DrellYan data for nuclear targets, we try to determine the correction difference and its effect on the anomaly. We find that the difference cannot be precisely determined at this stage due to the lack of data which are sen...

The object of this brief review is to reconcile different points of view on how the spin of proton is made up from its constituents. On the basis of naive quark model with flavour symmetry such as isospin or SU(3) one finds a static description. On the contrary the local SU(3) colour symmetry gives a dynamical view. Both these views are contrasted and the role of U(1) axial anomaly and the ambi...

We give a prescription for calculating the holographic Weyl anomaly in arbitrary dimensions within the framework based on the Hamilton-Jacobi equation proposed by de Boer, Verlinde and Verlinde. A few sample calculations are made and shown to agree with the ones obtained so far. We further discuss how to take continuum limits, and argue that the holographic renormalization group may describe th...

This is a survey of the current experimental information on some of the interesting issues in neutrino physics: neutrino species, neutrino masses, neutrino magnetic moments, solar neutri-nos, and the atmospheric neutrino anomaly.

We show the presence of Poincare anomaly in Maxwell-Chern-Simons theory = with an explicit mass term, in 2+1-dimensions.
