Comparing D-branes and Black Holes with 0- and 6-brane Charge
John M. Pierre
We consider configurations of D6-branes with D0-brane charge given by recent work of Taylor and compute interaction potentials with various D-brane probes using a 1-loop open strin…
Interactions of Eight-branes in String Theory and M(atrix) Theory
John M. Pierre
We consider eight-brane configurations in M(atrix) theory and compute their interaction potentials with gravitons, membranes, and four-branes. We compare these results with the int…
On the Moduli Space of N = 2 Supersymmetric G_2 Gauge Theory
Karl Landsteiner, John M. Pierre, Steven B. Giddings
We apply the method of confining phase superpotentials to N = 2 supersymmetric Yang-Mills theory with the exceptional gauge group G_2. Our findings are consistent with the spectral…
Some exact results in supersymmetric theories based on exceptional groups
Steven B. Giddings, John M. Pierre
We begin an investigation of supersymmetric theories based on exceptional groups. The flat directions are most easily parameterized using their correspondence with gauge invariant…
