Charm mass effects in the static energy computed in 2+1+1 flavor lattice QCD
Johannes Heinrich Weber, Nora Brambilla, Rafael L. Delgado +5
We report our analysis for the static energy in (2+1+1)-flavor QCD over a wide range of lattice spacings and several quark masses. We obtain results for the static energy out to di…
Unitarized one-loop graviton-graviton scattering
Rafael L. Delgado, Antonio Dobado, Domènec Espriu
In this work we interpret the Einstein-Hilbert (EH) Lagrangian of gravitation as the first term of a low-energy effective theory similar to those considered in the chiral Lagrangia…
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…
Seeking for resonances in unitarized one-loop graviton-graviton scattering
Rafael L. Delgado, Antonio Dobado, Domènec Espriu
Some effective field theories exhibit dynamical resonances that, when properly included, mitigate their bad behaviour at high energies. Unitarization of the partial wave amplitudes…
Static Energy in ()-Flavor Lattice QCD: Scale Setting and Charm Effects
TUMQCD Collaboration, Nora Brambilla, Rafael L. Delgado +6
We present results for the static energy in ()-flavor QCD over a wide range of lattice spacings and several quark masses, including the physical quark mass, with ensembles o…
The static energy in 2+1+1-flavor QCD
Sebastian Steinbeißer, Nora Brambilla, Rafael L. Delgado +5
We report on the status of the analysis of the static energy in -flavor QCD. The static energy is obtained by measuring Wilson line correlators in Coulomb gauge using the HI…

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…

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…

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…
