The decay of quantum D-branes
Jan Ambjorn, Romuald A. Janik
We study the {\em quantum} decay of D0-branes in two-dimensional 0B string theory. The quantum nature of the branes provides a natural cut-off for the closed string emission rate.…

Towards a diagrammatic derivation of the Veneziano-Yankielowicz-Taylor superpotential
Jan Ambjorn, Romuald A. Janik
We show how it is possible to integrate out chiral matter fields in N=1 supersymmetric theories and in this way derive in a simple diagrammatic way the $N_f S \log S - S \log \det…
