Nonperturbative Adler-Bardeen Theorem

1.1 Anomalies in QFT. The chiral anomaly appears as a quantum correction to the conservation of the axial current for massless fermions. A crucial property is the anomaly nonrenormalization, which says that the chiral anomaly is given exactly by its lower order contribution. This property was proved first for QED4 in [AB] in the well known Adler-Bardeen Theorem: it was shown that there is a dra...

Hydrodynamic Simulations of the Bardeen–Petterson Effect

We present SPH simulations of accretion discs in orbit about rotating compact objects, such as black holes and neutron stars, and study the structure of warped discs produced by the Bardeen-Petterson effect. We calculate the transition radius out to which the disc specific angular momentum vector is aligned with that of the black hole. We focus on the parameter regime where the warp dynamics ar...

From the Dean.

Recently, I was walking though the front hallway of Weiskotten Hall late in the evening, thinking about all the things I had to do in the next day, and looked up from my worry to see something I had missed after 21 years at Upstate. I am not sure how I missed it since it’s 3 X 6 feet, hangs on the wall and is immortalized in bronze and 4 inch letters, but I did. When I saw it, it stopped me in ...

Introduction Landsat Thematic Mapper ( TM ) imagery was used to analyze patterns of landscape diversity in the seasonal tropical forests of northeastern Guatemala. TM radiance and the radiance coefficient of variation (CV) were significant in discriminating land-cover types. Cluster analysis of TM4, TM5, and TM7 radiance produced six distinct types of landcover. Green leaf biomass from TM4 and ...
