Thermal Metastable Strings in One-Scale Models and Gravitational Waves
Arturo de Giorgi, James Ingoldby, Valentin V. Khoze +1
Metastable cosmic strings provide a cosmological interpretation of the nanohertz stochastic gravitational wave background reported by Pulsar Timing Array (PTA) experiments. We revi…
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…
Metastable Strings and Gravitational Waves in One-Scale Models
James Ingoldby, Valentin V. Khoze, Jessica Turner
Metastable cosmic strings provide a minimal and predictive origin for the stochastic gravitational-wave background reported by Pulsar Timing Array experiments. We analyse this poss…
Dilaton Forbidden Dark Matter
Thomas Appelquist, James Ingoldby, Maurizio Piai
Dilaton effective field theory (dEFT) describes the long distance behavior of certain confining, near-conformal gauge theories that have been studied via lattice computation. Pseud…
Dilaton Effective Field Theory
Thomas Appelquist, James Ingoldby, Maurizio Piai
We review and extend recent studies of dilaton effective field theory (dEFT) which provide a framework for the description of the Higgs boson as a composite structure. We first des…
Composite two-Higgs doublet model from dilaton effective field theory
Thomas Appelquist, James Ingoldby, Maurizio Piai
We construct a composite two-Higgs-doublet model (2HDM) within the context of dilaton effective field theory. This EFT describes the particle spectrum observed in lattice simulatio…
Goldstone Boson Scattering with a Light Composite Scalar
T. Appelquist, R. C. Brower, K. K. Cushman +14
The appearance of a light composite scalar resonance in nearly conformal gauge-fermion theories motivates further study of the low energy structure of these theories. To this…
A Near-Conformal Composite Higgs Model
Thomas Appelquist, James Ingoldby, Maurizio Piai
We analyze a composite Higgs model based on the confining gauge theory with Dirac fermions in the fundamental representation. This gauge theory has been studied o…
EFT anomalous dimensions from the S-matrix
Joan Elias Miró, James Ingoldby, Marc Riembau
We use the on-shell S-matrix and form factors to compute anomalous dimensions of higher dimension operators in the Standard Model Effective Field Theory. We find that in many insta…
The Dilaton Potential and Lattice Data
Thomas Appelquist, James Ingoldby, Maurizio Piai
We study an effective field theory (EFT) describing the interaction of an approximate dilaton with a set of pseudo-Nambu-Goldstone bosons (pNGBs). The EFT is inspired by, and emplo…
Linear Sigma EFT for Nearly Conformal Gauge Theories
T. Appelquist, R. C. Brower, G. T. Fleming +11
We construct a generalized linear sigma model as an effective field theory (EFT) to describe nearly conformal gauge theories at low energies. The work is motivated by recent lattic…
Analysis of a Dilaton EFT for Lattice Data
Thomas Appelquist, James Ingoldby, Maurizio Piai
In a recent paper, we developed and applied a dilaton-based effective field theory (EFT) to the analysis of lattice-simulation data for a class of confining gauge theories with nea…
Dilaton EFT Framework For Lattice Data
Thomas Appelquist, James Ingoldby, Maurizio Piai
We develop an effective-field-theory (EFT) framework to analyze the spectra emerging from lattice simulations of a large class of confining gauge theories. Simulations of these the…
A spartan model for the LHC diphoton excess
Thomas Appelquist, James Ingoldby, Maurizio Piai +1
We propose a simple model accommodating the reported 750 GeV diphoton excess seen in the first 13-TeV run of the LHC. It leads to testable predictions, in particular for di-lepton…
Spectrum-doubled Heavy Vector Bosons at the LHC
Thomas Appelquist, Yang Bai, James Ingoldby +1
We study a simple effective field theory incorporating six heavy vector bosons together with the standard-model field content. The new particles preserve custodial symmetry as well…
