IR side of bounds on Theories with Spontaneously Broken Lorentz Symmetry

Francesco Serra, Leonardo G. Trombetta

In nature, some UV features of dynamics are reflected in IR quantities. In fully relativistic theories, this connection can be probed through the analyticity properties of scatteri…

Five-point Superluminality Bounds

Francesco Serra, Leonardo G. Trombetta

We investigate how the speed of propagation of physical excitations is encoded in the coefficients of five-point interactions. This leads to a superluminality bound on scalar five-…
