Learning Trivializing Flows
David Albandea, Luigi Del Debbio, Pilar Hernández +3
The recent introduction of Machine Learning techniques, especially Normalizing Flows, for the sampling of lattice gauge theories has shed some hope on improving the sampling effici…

New bounds on axion-like particles from MicroBooNE
Pilar Coloma, Pilar Hernández, Salvador Urrea
Neutrino experiments lie at the edge of the intensity frontier and therefore can be exploited to search for new light particles weakly coupled to the visible sector. In this work w…
A lattice study of scattering at large
Jorge Baeza-Ballesteros, Pilar Hernández, Fernando Romero-López
We present the first lattice study of pion-pion scattering with varying number of colors, . We use lattice simulations with four degenerate quark flavors, $N_\text{f}=4…
Improved topological sampling for lattice gauge theories
David Albandea, Pilar Hernández, Alberto Ramos +1
Standard sampling algorithms for lattice QCD suffer from topology freezing (or critical slowing down) when approaching the continuum limit, thus leading to poor sampling of the dis…
Topological sampling through windings
David Albandea, Pilar Hernández, Alberto Ramos +1
We propose a modification of the Hybrid Monte Carlo (HMC) algorithm that overcomes the topological freezing of a two-dimensional gauge theory with and without fermion conten…
Dissecting the rule at large
Andrea Donini, Pilar Hernández, Carlos Pena +1
We study the scaling of kaon decay amplitudes with the number of colours, , in a theory with four degenerate flavours, . In this scenario, two current-current operators…
New constraints on Heavy Neutral Leptons from Super-Kamiokande data
Pilar Coloma, Pilar Hernández, Víctor Muñoz +1
Heavy neutral leptons are predicted in many extensions of the Standard Model with massive neutrinos. If kinematically accessible, they can be copiously produced from kaon and pion…
Meson interactions at large from Lattice QCD
Fernando Romero-López, Andrea Donini, Pilar Hernández +1
We report on the computation of the scaling of QCD observables with the number of colours, . For this, we use dynamical configurations with four active flavours, , and…
Large scaling of meson masses and decay constants
Pilar Hernández, Carlos Pena, Fernando Romero-López
We perform an calculation of the scaling of the low-energy couplings of the chiral Lagrangian of low-energy strong interactions, extracted from the mass…
N_f=2 chiral dynamics in the mixed chiral regime
Pilar Hernández, Silvia Necco, Carlos Pena +1
We present a study of the pseudoscalar propagator in the mixed chiral regime with valence quark masses in the ε-regime and sea quark masses in the p-regime. We first show the NNLO…
Mixed action computations on fine dynamical lattices
F. Bernardoni, N. Garron, P. Hernandez +2
We report on our first experiences in simulating Neuberger valence fermions on CLS configurations with light sea quark masses and small lattice spacings. Valence quark mass…
Finite Volume Scaling of Pseudo Nambu-Goldstone Bosons in QCD
F. Bernardoni, P. H. Damgaard, H. Fukaya +1
We consider chiral perturbation theory in a finite volume and in a mixed regime of quark masses. We take N_l light quarks near the chiral limit, in the so-called epsilon-regime, wh…
Residual mass effects in improved domain wall fermions
Pilar Hernández, Karl Jansen, Kei-ichi Nagai
In order to improve simulations with domain wall fermions (DWFs), it has been suggested to project out a number of low-lying eigenvalues of the 4-dimensional Dirac operator that ge…
