Veneziano Variations: How Unique are String Amplitudes?
Clifford Cheung, Grant N. Remmen
String theory offers an elegant and concrete realization of how to consistently couple states of arbitrarily high spin. But how unique is this construction? In this paper we derive…
Multifield Positivity Bounds for Inflation
Marat Freytsis, Soubhik Kumar, Grant N. Remmen +1
Positivity bounds represent nontrivial limitations on effective field theories (EFTs) if those EFTs are to be completed into a Lorentz-invariant, causal, local, and unitary framewo…
Accumulation-Point Amplitudes in String Theory
Juan Maldacena, Grant N. Remmen
We point out some common qualitative features of the Coon amplitude$\unicode{x2014}$a family of deformations of the Veneziano amplitude with logarithmic Regge trajectories$\unicode…
Spinning Sum Rules for the Dimension-Six SMEFT
Grant N. Remmen, Nicholas L. Rodd
We construct new dispersive sum rules for the effective field theory of the standard model at mass dimension six. These spinning sum rules encode information about the spin of UV s…
UV-Complete Gravity Amplitudes and the Triple Product
Yu-tin Huang, Grant N. Remmen
We construct an infinite class of new ultraviolet-complete four-graviton scattering amplitudes that reduce to Einstein gravity at low energies, vanish at high energies, are meromor…
