The Baker-Coon-Romans -point amplitude and an exact field theory limit of the Coon amplitude
Nicholas Geiser
We study the -point Coon amplitude discovered first by Baker and Coon in the 1970s and then again independently by Romans in the 1980s. This Baker-Coon-Romans (BCR) amplitude re…
Generalized Veneziano and Virasoro amplitudes
Nicholas Geiser, Lukas W. Lindwasser
We analyze so-called generalized Veneziano and generalized Virasoro amplitudes. Under some physical assumptions, we find that their spectra must satisfy an over-determined set of n…
Properties of infinite product amplitudes: Veneziano, Virasoro, and Coon
Nicholas Geiser, Lukas W. Lindwasser
We detail the properties of the Veneziano, Virasoro, and Coon amplitudes. These tree-level four-point scattering amplitudes may be written as infinite products with an infinite seq…
Integrating three-loop modular graph functions and transcendentality of string amplitudes
Eric D'Hoker, Nicholas Geiser
Modular graph functions (MGFs) are -invariant functions on the Poincaré upper half-plane associated with Feynman graphs of a conformal scalar field on a…
