The standard model as an effective field theory

I Brivio, M Trott - Physics Reports, 2019 - Elsevier
Projecting measurements of the interactions of the known Standard Model (SM) states into
an effective field theory (EFT) framework is an important goal of the LHC physics program …

[HTML][HTML] ALPs effective field theory and collider signatures

I Brivio, MB Gavela, L Merlo, K Mimasu, JM No… - The European Physical …, 2017 - Springer

[HTML][HTML] The effective chiral Lagrangian for a light dynamical “Higgs particle”

R Alonso, MB Gavela, L Merlo, S Rigolin, J Yepes - Physics Letters B, 2013 - Elsevier
We generalize the basis of CP-even chiral effective operators describing a dynamical Higgs
sector, to the case in which the Higgs-like particle is light. Gauge and gauge-Higgs …

Charge disproportionation without charge transfer in the rare-earth-element nickelates as a possible mechanism for the metal-insulator transition

S Johnston, A Mukherjee, I Elfimov, M Berciu… - Physical review …, 2014 - APS
We study a model for the metal-insulator (MI) transition in the rare-earth-element nickelates
R NiO 3, based upon a negative charge transfer energy and coupling to a rocksaltlike lattice …

Model-discriminating power of lepton flavor violating decays

A Celis, V Cirigliano, E Passemar - Physical Review D, 2014 - APS
Within an effective field theory framework, we discuss the possibility to discriminate among
different operators that contribute to lepton flavor violating (LFV) τ decays. Correlations …

Geometry of the scalar sector

R Alonso, EE Jenkins, AV Manohar - Journal of High Energy Physics, 2016 - Springer
A bstract The S-matrix of a quantum field theory is unchanged by field redefinitions, and so it
only depends on geometric quantities such as the curvature of field space. Whether the …

Disentangling a dynamical Higgs

I Brivio, T Corbett, OJP Éboli, MB Gavela… - Journal of High Energy …, 2014 - Springer
A bstract The pattern of deviations from Standard Model predictions and couplings is
different for theories of new physics based on a non-linear realization of the SU (2) L× U (1) …

Nonresonant searches for axionlike particles at the LHC

MB Gavela, JM No, V Sanz, JF de Trocóniz - Physical Review Letters, 2020 - APS
We propose a new collider probe for axionlike particles (ALPs), and more generally for
pseudo-Goldstone bosons: nonresonant searches that take advantage of the derivative …
