Dihadron Fragmentation Functions in the NJL-jet model
The NJL-jet model provides a framework for calculating fragmentation
functions without introducing ad hoc parameters. Here the NJL-jet model is
extended to investigate dihadron fragmentation functions.Comment: 4 pages, 5 figures, Proceedings of 8th Circum-Pan-Pacific Symposium

Concept to standardize space vehicle piggyback experiment modules
Study investigates the use of spent launch vehicle stages and modules to support earth orbital operations and functions after successful completion of the primary mission. Emphasis is placed primarily on determination of those uses that afford the greatest utility with minimum possibility of degradation to the primary mission
D=7 SU(2) Gauged Supergravity From D=10 Supergravity
The theory of SU(2) gauged seven-dimensional supergravity is obtained by
compactifying ten dimensional N=1 supergravity on the group manifold SU(2).Comment: 10 pages. References added and some comments modifie
Metrics Admitting Killing Spinors In Five Dimensions
BPS black hole configurations which break half of supersymmetry in the theory
of N=2, d=5 supergravity coupled to an arbitrary number of abelian vector
multiplets are discussed. A general class of solutions comprising all known BPS
rotating black hole solutions is obtained.Comment: 15 pages, Late
Testing quantum adiabaticity with quench echo
Adiabaticity of quantum evolution is important in many settings. One example
is the adiabatic quantum computation. Nevertheless, up to now, there is no
effective method to test the adiabaticity of the evolution when the
eigenenergies of the driven Hamiltonian are not known. We propose a simple
method to check adiabaticity of a quantum process for an arbitrary quantum
system. We further propose a operational method for finding a uniformly
adiabatic quench scheme based on Kibble-Zurek mechanism for the case when the
initial and the final Hamiltonians are given. This method should help in
implementing adiabatic quantum computation.Comment: This is a new version. Some typos in the New Journal of Physics
version have been correcte
Solid weak BCC-algebras
We characterize weak BCC-algebras in which the identity is
satisfied only in the case when elements belong to the same branch
