A tale of two exponentiations in supergravity at subleading level
Paolo Di Vecchia, Stephen G. Naculich, Rodolfo Russo +2
High-energy massless gravitational scattering in supergravity was recently analyzed at leading level in the deflection angle, uncovering an interesting connection betw…
Generalized covariant prescriptions for averaging cosmological observables
Giuseppe Fanizza, Maurizio Gasperini, Giovanni Marozzi +1
We present two new covariant and general prescriptions for averaging scalar observables on spatial regions typical of the observed sources and intersecting the past light-cone of a…
Photo-production And Decay
Giancarlo Rossi, Gabriele Veneziano
The 2015 LHCb discovery of a structure (denoted by ) decaying in and conjectured to be a penta-quark state, has triggered a renewed interest in the question of poss…
A tale of two exponentiations in supergravity
Paolo Di Vecchia, Andrés Luna, Stephen G. Naculich +3
The structure of scattering amplitudes in supergravity theories continues to be of interest. Recently, the amplitude for scattering in supergravity wa…
Soft gravitational radiation from ultra-relativistic collisions at sub- and sub-sub-leading order
Andrea Addazi, Massimo Bianchi, Gabriele Veneziano
Using soft-graviton theorems a well-known zero-frequency limit (ZFL) for the gravitational radiation flux is re-derived and extended to order and ${\cal…
Infrared features of gravitational scattering and radiation in the eikonal approach
Marcello Ciafaloni, Dimitri Colferai, Gabriele Veneziano
Following a semi-classical eikonal approach --- justified at transplanckian energies order by order in the deflection angle --- w…
