BCJ and KK Relations from BRST Symmetry and Supergravity Amplitudes
P. A. Grassi, A. Mezzalira, L. Sommovigo
We use Pure Spinor string theory to construct suitable kinematical factors which explicitly satisfy the Kleiss-Kuijf (KK) relations. Using the formula conceived by Bern et al. and…
On Supergravity Amplitudes from Pure Spinor Strings
P. A. Grassi, L. Sommovigo
We use Pure Spinor String Theory to construct suitable building blocks to arrange the structure of supergravity amplitudes with n-points and at higher loops in a very convenient wa…
Supersymmetric Fluid Dynamics
P. A. Grassi, A. Mezzalira, L. Sommovigo
Recently Navier-Stokes (NS) equations have been derived from the duality between the black branes and a conformal fluid on the boundary of AdS_5. Nevertheless, the full corresponde…
D=4, N=2 Gauged Supergravity coupled to Vector-Tensor Multiplets
Laura Andrianopoli, Riccardo D'Auria, Luca Sommovigo +1
We construct the general four-dimensional N=2 supergravity theory coupled to vector and vector-tensor multiplets only. Consistency of the construction requires the introduction of…
Pure Spinor Integration from the Collating Formula
Pietro Antonio Grassi, Luca Sommovigo
We use the technique developed by Becchi and Imbimbo to construct a well-defined BRST-invariant path integral formulation of pure spinor amplitudes. The space of pure spinors can b…
Quantum Computing with Superqubits
Leonardo Castellani, Pietro Antonio Grassi, Luca Sommovigo
We analyze some aspects of quantum computing with super-qubits (squbits). We propose the analogue of a superfield formalism, and give a physical interpretation for the Grassmann co…
