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…
Characterisation of the Bedretto Underground Site for Fundamental Physics Experiments
Björn Penning, Nicolas Angelides, Laura Baudis +33
Underground laboratories provide the ultra-low background and low-vibration environments essential for rare-event searches, gravitational-wave detection, and quantum-sensing techno…
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…
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…
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…
