Dilaton Effective Field Theory across the Conformal Edge
Thomas Appelquist, James Ingoldby, Maurizio Piai
Dilaton effective field theory (dEFT) can be employed to analyze lattice data in gauge theories that lie in close proximity of the lower edge of the conformal window. Under special…
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…
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…
Confinement transition to gravitational waves in the one-flavor Hyper Stealth Dark Matter theory
V. Ayyar, R. C. Brower, G. T. Fleming +11
The thermodynamics of the gauge theory with a single flavor of fundamental quarks is analyzed on the lattice with dynamical fermion simulations, which is the low-energy sec…
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…
Hamiltonian Truncation Framework for Gauge Theories on the Interval
Rachel Houtz, James Ingoldby
In this work, we investigate gauge theories in two dimensions nonperturbatively using the Hamiltonian truncation approach. Working on a spatial interval and adopting the axial gaug…
