QuantumFDTD -- A computational framework for the relativistic Schrödinger equation
Rafael L. Delgado, Sebastian Steinbeißer, Michael Strickland +1
We extend the publicly available quantumfdtd code. It was originally intended for solving the time-independent three-dimensional Schrödinger equation via the finite-difference time…
LHC constraints on hidden gravitons
J. A. R. Cembranos, R. L. Delgado, H. Villarrubia-Rojo
We analyze LHC data in order to constrain the parameter space of new spin-2 particles universally coupled to the energy-momentum tensor. These new hypothetical particles are the so…
The Relativistic Schrödinger Equation through FFTW3: An Extension of quantumfdtd
Rafael L. Delgado, Sebastian Steinbeißer, Michael Strickland +1
In order to solve the time-independent three-dimensional Schrödinger equation, one can transform the time-dependent Schrödinger equation to imaginary time and use a parallelized it…
VBSCan Mid-Term Scientific Meeting
Julien Baglio, Alessandro Ballestrero, Riccardo Bellan +48
This document summarises the talks and discussions happened during the VBSCan Mid-Term Scientific Meeting workshop. The VBSCan COST action is dedicated to the coordinated study of…
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…

Rafael L. Delgado, Antonio Dobado, Felipe J. Llanes-Estrada
Higgs Effective Field Theory can be used to study vector-boson elastic scattering at the high energies relevant for the LHC. For most of the parameter space, the scattering is stro…

We estimate production cross sections for 2-body resonances of the Electroweak Symmetry Breaking sector (in and rescattering) from scattering. We employ unit…
Electroweak resonances in HEFT
Felipe J. Llanes-Estrada, Rafael L. Delgado y Antonio Dobado
Due to the gap between the known 100 GeV scale and new physics if any, it is natural to employ an effective one-loop Lagrangian (HEFT) for the particles of the Electroweak Symmetry…
