Bounds on scattering amplitudes of non-identical scalar particles in 4d
Gabriele Ferretti, Denis Karateev, Alessandro Piazza +1
We initiate the study of two-to-two scattering amplitudes involving two distinct scalar particles in spacetime dimensions using the primal S-matrix bootstrap. We impose a $…
Natural semi-direct gauge mediation and D-branes at singularities
Riccardo Argurio, Matteo Bertolini, Gabriele Ferretti +1
We consider semi-direct gauge mediation models of supersymmetry breaking where the messengers are composite fields and their supersymmetric mass is naturally generated through quar…
Massless fermionic bound states and the gauge/gravity correspondence
Riccardo Argurio, Gabriele Ferretti, Christoffer Petersson
We study the equations of motion of fermions in type IIB supergravity in the context of the gauge/gravity correspondence. The main motivation is the search for normalizable fermion…
Higher Charges in Dynamical Spin Chains for SYM Theory
Abhishek Agarwal, Gabriele Ferretti
We construct, to the first two non-trivial orders, the next conserved charge in the su(2|3) sector of N=4 Super Yang-Mills theory. This represents a test of integrability in a sect…
One-Loop QCD Spin Chain and its Spectrum
N. Beisert, G. Ferretti, R. Heise +1
We study the renormalization of gauge invariant operators in large Nc QCD. We compute the complete matrix of anomalous dimensions to leading order in the 't Hooft coupling and stud…
New Integrable Structures in Large-N QCD
Gabriele Ferretti, Rainer Heise, Konstantin Zarembo
We study the anomalous dimensions of single trace operators composed of field strengths in large-N QCD. The matrix of anomalous dimensions is the Hamiltonian of a compact…
