The Potential of HEFT and the scale of New Physics
Rodrigo Alonso, Susobhan Chattopadhyay, James Ingoldby
We employ a geometric framework to compute the leading high-energy behaviour of tree-level scattering amplitudes in theories containing Nambu-Goldstone bosons and a single Higg…

Assessing (H)EFT theory errors by pitting EoM against Field Redefinitions
Rodrigo Alonso, Christoph Englert, Wrishik Naskar +1
Truncations of effective field theory expansions are technically necessary but inherently intertwined with the redundancies of general field redefinitions. This can be viewed as a…

Walls, bubbles and doom -- the cosmology of HEFT
Rodrigo Alonso, Juan Carlos Criado, Rachel Houtz +1
As experiment charts new territory at the electroweak scale, the enterprise to characterise all possible theories becomes all the more necessary. In the absence of new particles, t…
