Branes in the M_D x M_d+ x M_d- Compactification of Type II String on S^1/Z_2 and Their Cosmologicval Applications

Devin, Michael; Ali, Tibra; Cleaver, Gerald; Wang, Anzhong; Wu, Qiang

In this paper, we study the implementation of brane worlds in type II string theory. Starting with the NS/NS sector of type II string, we first compactify the (D + d+ + d−)-dimensional spacetime, and reduce the corresponding ...
Charging and Growth of Fractal Dust Grains

Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )

The structure and evolution of aggregate grains formed within a plasma environment are dependent on the charge acquired by the micron-sized dust grains during the coagulation process. The manner in which the charge is ...
Note on a NAHE Variation

Greenwald, Jared; Pechan, Kristen; Renner, Tim; Ali, Tibra; Cleaver, Gerald

We present a variation of the NAHE-basis for free fermionic heterotic string mod- els. By rotating some of boundary conditions of the NAHE periodic/anti-periodic fermions {ym, ym, wm, wm,}, for m = 1 to 6, associated with ...
A Simple Introduction to Particle Physics: Part II Geometric Foundations and Relativity

Robinson, Matthew; Ali, Tibra; Cleaver, Gerald

This is the second in a series of papers intended to provide a basic overview of some of the major ideas in particle physics. Part I [40] was primarily an algebraic exposition of gauge theories. We developed the group ...
