Genus four superstring measures
Sergio L. Cacciatori, Francesco Dalla Piazza, Bert van Geemen
A main issue in superstring theory are the superstring measures. D'Hoker and Phong showed that for genus two these reduce to measures on the moduli space of curves which are determ…
Modular Forms and Three Loop Superstring Amplitudes
Sergio L. Cacciatori, Francesco Dalla Piazza, Bert van Geemen
We study a proposal of D'Hoker and Phong for the chiral superstring measure for genus three. A minor modification of the constraints they impose on certain Siegel modular forms lea…
Conservation laws and scattering for de Sitter classical particles
S. Cacciatori, V. Gorini, A. Kamenshchik +1
Starting from an intrinsic geometric characterization of de Sitter timelike and lightlike geodesics we give a new description of the conserved quantities associated with classical…
Two loop superstring amplitudes and S_6 representations
Sergio Cacciatori, Francesco Dalla Piazza
In this paper we describe how representation theory of groups can be used to shorten the derivation of two loop partition functions in string theory, giving an intrinsic descriptio…
Geometry of four-dimensional Killing spinors
S. L. Cacciatori, M. M. Caldarelli, D. Klemm +2
The supersymmetric solutions of N=2, D=4 minimal ungauged and gauged supergravity are classified according to the fraction of preserved supersymmetry using spinorial geometry techn…
New constraint for Black Holes in N=2, D=5 supergravity with matter
S. L. Cacciatori, A. Celi
With the general aim to classify BPS solutions in N=2, D=5 supergravity with hypermultiplets and vector multiplets, here we consider a family of static spacetime metrics containing…
