Bound States in 2d Yukawa Theory from Hamiltonian Truncation
Olivier Delouche, Kara Farnsworth, Francesco Riva
We study the spectrum of two-dimensional Yukawa theory using Hamiltonian truncation, with a focus on bound states. We extend the framework of Hamiltonian truncation effective theor…
Positivity with Long-Range Interactions
B. Bellazzini, J. Berman, G. Isabella +3
We introduce infrared finite, analytic, crossing symmetric, Regge behaved, and Lorentz invariant amplitudes , labeled by the experimental energy resolut…
The Rise of Linear Trajectories
Yu-tin Huang, Sara Ricossa, Francesco Riva +1
In this letter, we consider constraints on the low-energy spectrum of amplitudes with higher-spin exchange. Assuming unitarity, crossing symmetry, and super-convergent high energy…
The EFT Bootstrap at Finite
Carl Beadle, Giulia Isabella, Davide Perrone +3
We explore the impact of loop effects on positivity in effective field theories emerging in the infrared from unitary and causal microscopic dynamics. Focusing on massless particle…
Non-Forward UV/IR Relations
Carl Beadle, Giulia Isabella, Davide Perrone +3
We study bounds arising from the analyticity and unitarity of scattering amplitudes in the context of effective field theories with massless particles. We provide an approach that…
Positivity Bounds on Massive Vectors
Francesco Bertucci, Johan Henriksson, Brian McPeak +3
In this paper, we explore positivity bounds for the effective field theory~(EFT) of a single weakly coupled massive vector field. The presence of both mass and spin makes the cross…
