We propose a formalism for the decay of the SU (3) nonets of the axial vector mesons of J P C = 1 +− , 1 ++ into a vector meson and a pseudoscalar which is based on a tensor formulation of the vector and axial vector fields. The formulation leads to a good reproduction of the different decay branching ratios and assuming vector meson dominance (VMD) it also leads to good results for the radiati...

We explore the effects of breaking and restoration of chiral and axial symmetries using an extended three-flavor Nambu-Jona-Lasinio model that incorporates explicitly the axial anomaly through the ’t Hooft interaction. We implement a temperature (density) dependence of the anomaly coefficient motivated by lattice results for the topological susceptibility. The spectrum of scalar and pseudoscala...

Period 08/15/98-11/30/00, Title Active Seismic Imaging of Axial Volcano, PI's William Menke & Maya Tolstoy. The region of Axial Volcano, Juan de Fuca Ridge region provides an excellent opportunity to study the interplay between active "hot spot" and "mid-ocean ridge" magmatic systems. Important questions include how the two magma systems are fed; their magma and heat budgets; the degree of inte...

We give a gauge-invariant treatment of the angular momentum sum-rule for the proton in terms of matrix elements of three gauge-invariant, local composite operators. These matrix elements are decomposed into three independent form factors, one of which is the flavour singlet axial charge. We further show that the axial charge cancels out of the sum-rule, so that it is unaffacted by the axial ano...

Abstract Automated computer generation of aesthetically pleasing artwork has been the subject research for several decades. The unsolved problem interest is how to please any audience without requiring too much their involvement in process creation. Two-dimensional pictures have received a lot attention; however, 3D remained relatively unexplored. This paper showcases an extended version Axial ...

The liquid axial dispersion inside modern structured packings (Sulzer Mellapak™ 500.Y, Raschig Super-Pak 350Y) and one random packing of the 4th generation (Raschig Super-Ring 0.3) was measured by means computed tomography. As gas velocity is known to have little effect on at low hydraulic load, all experiments were conducted without countercurrent flow loads B = 10, 15, 20 m3m−2h−1 in a column...
