Non-Planar String Networks on Tori

Type II strings in D=5 contain particle-like 1/8 supersymmetric BPS states.In this note we give a string-network representation of such states byconsidering periodic non-planar $(p,q,r)$-string networks of eight dimensionaltype II string theory on $T^3$. We obtain the BPS mass formula of such states...

Sumario:Type II strings in D=5 contain particle-like 1/8 supersymmetric BPS states.In this note we give a string-network representation of such states byconsidering periodic non-planar $(p,q,r)$-string networks of eight dimensionaltype II string theory on $T^3$. We obtain the BPS mass formula of such states,in terms of charges and generating-vectors of the torus, and show itsinvariance under an $SL(3, Z)\times SL(3, Z)$ group of transformations. Resultsare then generalized to string-networks associated with the $SL(5, Z)
