    • 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 J.; Ali, Tibra; Cleaver, Gerald B.; Wang, Anzhong.; Wu, Qiang, 1977- (2010-07-09)
      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 ...
    • Note on a NAHE Variation 

      Greenwald, Jared.; Pechan, Kristen.; Renner, Timothy, 1984-; Ali, Tibra; Cleaver, Gerald B. (2010-07-09)
      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 Brandon, 1981-; Ali, Tibra; Cleaver, Gerald B. (2010-07-09)
      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 ...
