Bound-states of D-branes in L-R asymmetric superstring vacua
Massimo Bianchi
We discuss bound-states of D-branes in truly L-R asymmetric and thus non-geometric Type II vacuum configurations with extended supersymmetry. We argue for their stability as a resu…
D-brane Instantons on the T^6/Z_3 orientifold
Massimo Bianchi, Francesco Fucito, Jose F. Morales
We give a detailed microscopic derivation of gauge and stringy instanton generated superpotentials for gauge theories living on D3-branes at Z_3-orientifold singularities. Gauge in…
Non-perturbative and Flux superpotentials for Type I strings on the Z_3 orbifold
Massimo Bianchi, Elias Kiritsis
Non-perturbative effects are studied for Type I strings on the Z_3 orbifold with Chan-Paton symmetry broken by Wilson lines. Generalizing previous analyses that have focussed on (b…
Instantons and Supersymmetry
Massimo Bianchi, Stefano Kovacs, Giancarlo Rossi
The role of instantons in describing non-perturbative aspects of globally supersymmetric gauge theories is reviewed. The cases of theories with N=1, N=2 and N=4 supersymmetry are d…
"Massive" Higher Spin Multiplets and Holography
M. Bianchi, V. Didenko
We review the extrapolation of the single-particle string spectrum on AdS(5)xS(5) to the Higher Spin enhancement point and the successful comparison of the resulting spectrum with…
Instantons and BPS Wilson loops
Massimo Bianchi, Michael B. Green, Stefano Kovacs
The one-instanton contribution to a circular BPS Wilson loop in N=4 SU(2) Yang--Mills theory is evaluated in semiclassical approximation. This article amplifies part of a talk give…
