Unitarity and Unitarization
Alexandre Salas-Bernárdez
This article reviews unitarization methods essential for extending Effective Field Theories (EFTs) beyond their perturbative limits, particularly in hadronic and electroweak (EW) s…
A global analysis of ALP-mediated multiboson production at the LHC
Fabian Esser, Alexandre Salas-Bernardez, Maria Ubiali +1
Axion-like particles (ALPs) provide a well-motivated framework for physics beyond the Standard Model, coupling to gauge bosons through dimension-five operators protected by an appr…
Di-Higgs production via Axion-Like Particles
Fabian Esser, Maeve Madigan, Alexandre Salas-Bernardez +2
Due to the pseudo-scalar nature of the axion-like particle (ALP), the CP- conserving production of two Higgs bosons via the ALP necessarily involves an additional Z or boson. W…
Spinning Pairs: Supporting Quark-Pair Creation from Landau Gauge Green's Functions
Reinhard Alkofer, Felipe J. Llanes-Estrada, Alexandre Salas-Bernardez
Abundant phenomenology suggests that strong decays from relatively low-excitation hadrons into other hadrons proceed by the creation of a light quark-antiquark pair with zero total…
Production of two, three, and four Higgs bosons: where SMEFT and HEFT depart
Rafael L. Delgado, Raquel Gómez-Ambrosio, Javier Martínez-Martín +2
In this article we study the phenomenological implications of multiple Higgs boson production from longitudinal vector boson scattering in the context of effective field theories.…
Split gluon masses in theories
Julia Gómez Concejo, Felipe J. Llanes-Estrada, Diego María-Almazán +1
We extend a known mass-gap equation for pure gluodynamics in global colour models (formulated in equal time quantization in Coulomb gauge) to one in which gluons split into two set…
SMEFT as a slice of HEFT's parameter space
Alexandre Salas-Bernardez, Juan J. Sanz-Cillero, Felipe J. Llanes-Estrada +1
The Standard Model Effective Field Theory (SMEFT) is the parametrization chosen to interpret many modern measurements. We have recently discussed, building on the work of other gro…
SMEFT is falsifiable through multi-Higgs measurements (even in the absence of new light particles)
Raquel Gómez-Ambrosio, Felipe J. Llanes-Estrada, Alexandre Salas-Bernárdez +1
From the embedding of the Standard Model Effective Field Theory (SMEFT) in the more general Higgs Effective Field Theory (HEFT), we expose correlations among the coefficients of th…
Explicit computation of jet functions in coordinate space
Alexandre Salas-Bernárdez
I review the main results leading to Factorization of QCD amplitudes in momentum space and, in view of the analogue results in coordinate space, the one-loop jet function in coordi…
The flair of Higgsflare: Distinguishing electroweak EFTs with
Raquel Gomez-Ambrosio, Felipe J. Llanes-Estrada, Alexandre Salas-Bernardez +1
The electroweak symmetry-breaking sector is one of the most promising and uncharted parts of the Standard Model; but it seems likely that new electroweak physics may be out of reac…
Resonances in unitarized HEFT at the LHC
Antonio Dobado, Felipe J. Llanes-Estrada, Alexandre Salas-Bernardez +1
Higgs Effective Field Theory (HEFT) is deployed to study elastic vector-boson scattering at the high LHC energies. The interaction is strong over most of the parameter space, with…
Chiral symmetry breaking for fermions charged under large Lie groups
Felipe J. Llanes-Estrada, Alexandre Salas-Bernárdez
We reexamine the dynamical generation of mass for fermions charged under various Lie groups with equal charge and mass at a high Grand Unification scale, extending the Renormalizat…
