String (gravi)photons, "dark brane photons", holography and the hypercharge portal
Pascal Anastasopoulos, Massimo Bianchi, Dario Consoli +1
The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly-coupled string theory. Both the direct mixing as well…
Freezing E3-brane instantons with fluxes
Massimo Bianchi, Andres Collinucci, Luca Martucci
E3-instantons that generate non-perturbative superpotentials in IIB N=1 compactifications are more frequent than currently believed. Worldvolume fluxes will typically lift the E3-b…
Current Algebra of the Pure Spinor Superstring in AdS(5) x S(5)
M. Bianchi, J. Kluson
We perform a Hamiltonian analysis of the classical type IIB superstring on AdS(5) x S(5) in the pure spinor approach. Taking the spatial components of the left-invariant (super)cur…
Anomalies, Anomalous U(1)'s and generalized Chern-Simons terms
P. Anastasopoulos, M. Bianchi, E. Dudas +1
A detailed analysis of anomalous U(1)'s and their effective couplings is performed both in field theory and string theory. It is motivated by the possible relevance of such couplin…
String amplitudes in the Hpp-wave limit of AdS3xS3
M. Bianchi, G. D'Appollonio, E. Kiritsis +1
We compute string amplitudes on pp-waves supported by NS-NS 3-form fluxes and arising in the Penrose limit of AdS3xS3xM. We clarify the role of the non-chiral accidental SU(2) symm…
