Exact two-dimensional superconformal R-symmetry and c-extremization
Francesco Benini, Nikolay Bobev
We uncover a general principle, dubbed c-extremization, which determines the exact R-symmetry of a two-dimensional unitary superconformal field theory with N=(0,2) supersymmetry. T…
Webs of five-branes and N=2 superconformal field theories
Francesco Benini, Sergio Benvenuti, Yuji Tachikawa
We describe configurations of 5-branes and 7-branes which realize, when compactified on a circle, new isolated four-dimensional N=2 superconformal field theories recently construct…
The N=2 cascade revisited and the enhancon bearings
Francesco Benini, Matteo Bertolini, Cyril Closset +1
Supergravity backgrounds with varying fluxes generated by fractional branes at non-isolated Calabi-Yau singularities had escaped a precise dual field theory interpretation so far.…
Gauge/gravity duality and the interplay of various fractional branes
Riccardo Argurio, Francesco Benini, Matteo Bertolini +2
We consider different types of fractional branes on a Z_2 orbifold of the conifold and analyze in detail the corresponding gauge/gravity duality. The gauge theory possesses a rich…
Warped Models in String Theory
Bobby Samir Acharya, Francesco Benini, Roberto Valandro
Warped models, originating with the ideas of Randall and Sundrum, provide a fascinating extension of the standard model with interesting consequences for the LHC. We investigate in…
The Coulomb branch of the Leigh-Strassler deformation and matrix models
Francesco Benini
The Dijkgraaf-Vafa approach is used in order to study the Coulomb branch of the Leigh-Strassler massive deformation of N=4 SYM with gauge group U(N). The theory has N=1 SUSY and an…
