Phenomenology of Chan-Paton Defects on Open Strings Open
This paper investigates the rˆole of defects on extended quantum objects by generalizing the Chan–Paton factors of string theory as bimodules, wherein left- and right-actions encode brane dynamics. We introduce the concept of Chan–Paton de…

PNDP Instantons in Two Dimensions Open
In this paper, we extend the PNDP braneworld scenario by introducing $\emph{$\sigma$-torsors}$, a topological invariant of the spinor bundle. We investigate instantons in two-dimensional conformal field theory using the $CFT_d \leftrightar…
