ALP pair production at the LHC
Ilaria Brivio, Simone Meoni, Davide Pagani
We study axion-like particle (ALP) pair production at the LHC, investigating its sensitivity to the simultaneous presence of dimension-5 and dimension-6 ALP interactions. Focusing…
POPxf: An Exchange Format for Polynomial Observable Predictions
Ilaria Brivio, Ken Mimasu, Peter Stangl +7
We introduce the Polynomial Observable Prediction Exchange Format, POPxf, a structured, machine-readable data format for the publication and exchange of semi-analytical theoretical…
Higgs pair production in gluon fusion to higher orders in Higgs Effective Field Theory
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
Higgs pair production offers the opportunity to probe correlations among the couplings of one or two Higgs bosons to fermions and gauge bosons. In this context, it serves as a powe…
The Art of Counting: a reappraisal of the HEFT expansion
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
We revisit the power counting of the Higgs Effective Field Theory (HEFT) from first principles, by requiring that predictions for physical observables follow a series expansion in…
Scalar Amplitudes from Fibre Bundle Geometry
Mohammad Alminawi, Ilaria Brivio, Joe Davighi
We compute tree-level -point scattering amplitudes in scalar field theories in terms of geometric invariants on a fibre bundle. All 0- and 2-derivative interactions are incorpor…
Jet Bundle Geometry of Scalar Field Theories
Mohammad Alminawi, Ilaria Brivio, Joe Davighi
For scalar field theories, such as those EFTs describing the Higgs, it is well-known that the 2-derivative Lagrangian is captured by geometry. That is, the set of operators with ex…
