Precision asymptotics of string amplitudes
Marco Maria Baccianti, Lorenz Eberhardt, Sebastian Mizera
Recent work revealed a tension between the Gross-Mende analysis of the high-energy fixed-angle behavior of string amplitudes and the explicit numerical data. Motivated by this puzz…
One-loop four-graviton string amplitude at finite
Marco Maria Baccianti, Lorenz Eberhardt, Sebastian Mizera
We evaluate the one-loop four-graviton scattering amplitude in type-II superstring theory exactly in . This result is achieved by combining physical insights into the $i\vareps…
Rademacher expansion of modular integrals
Marco Maria Baccianti, Jeevan Chandra, Lorenz Eberhardt +2
We develop a method to evaluate integrals of non-holomorphic modular functions over the fundamental domain of the torus with modular parameter analytically. It proceeds in two…
Regge Limit of One-Loop String Amplitudes
Pinaki Banerjee, Lorenz Eberhardt, Sebastian Mizera
We study the high-energy limit of one-loop string amplitudes at fixed momentum transfer. For the closed string, the high-energy behaviour of the amplitudes can be determi…
Lorentzian contours for tree-level string amplitudes
Lorenz Eberhardt, Sebastian Mizera
We engineer compact contours on the moduli spaces of genus-zero Riemann surfaces that achieve analytic continuation from Euclidean to Lorentzian worldsheets. These generalized Poch…
Principal Landau Determinants
Claudia Fevola, Sebastian Mizera, Simon Telen
We reformulate the Landau analysis of Feynman integrals with the aim of advancing the state of the art in modern particle-physics computations. We contribute new algorithms for com…
