Tidal effects for spinning particles
Rafael Aoude, Kays Haddad, Andreas Helset
Expanding on the recent derivation of tidal actions for scalar particles, we present here the action for a tidally deformed spin- particle. Focusing on operators containing tw…
Tidal effects in quantum field theory
Kays Haddad, Andreas Helset
We apply the Hilbert series to extend the gravitational action for a scalar field to a complete, non-redundant basis of higher-dimensional operators that is quadratic in the scalar…
Exact SMEFT formulation and expansion to
Chris Hays, Andreas Helset, Adam Martin +1
The Standard Model Effective Field Theory (SMEFT) theoretical framework is increasingly used to interpret particle physics measurements and constrain physics beyond the Standard Mo…
The double copy for heavy particles
Kays Haddad, Andreas Helset
We show how to double-copy Heavy Quark Effective Theory (HQET) to Heavy Black Hole Effective Theory (HBET) for spin . In particular, the double copy of spin- HQET with…
On-shell heavy particle effective theories
Rafael Aoude, Kays Haddad, Andreas Helset
We introduce on-shell variables for Heavy Particle Effective Theories (HPETs) with the goal of extending Heavy Black Hole Effective Theory to higher spins and of facilitating its a…
The Geometric Standard Model Effective Field Theory
Andreas Helset, Adam Martin, Michael Trott
We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the $\sqrt{2 \langle H^\dagger H \ran…
