Open AccessFLAG Review 2021
We review lattice results related to pion, kaon, D-meson, B-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report o...

Open AccessNon-perturbative renormalisation and running of BSM four-quark operators in \(N_\mathrm {\scriptstyle f}=2\) QCD
We perform a non-perturbative study of the scale-dependent renormalisation factors of a complete set of dimension-six four-fermion operators without power subtractions. The renormalisation-group (RG) running i...

Open AccessReview of lattice results concerning low-energy particle physics
We review lattice results related to pion, kaon, D- and B-meson physics with the aim of making them easily accessible to the particle-physics community. More specifically, we report on the determination of the li...

Open AccessB-physics from Nf = 2 tmQCD: the Standard Model and beyond
We present a lattice QCD computation of the b-quark mass, the B and B s decay constants, the B-mixing bag prameters for the full four-fermion operator b...

Open AccessKaon mixing beyond the SM from Nf = 2 tmQCD and model independent constraints from the UTA
We present the first unquenched, continuum limit, lattice QCD results for the matrix elements of the operators describing neutral kaon oscillations in extensions of the Standard Model. Owing to the accuracy of...

Isospin breaking effects due to the up-down mass difference in lattice QCD
We present a new method to evaluate with high precision leading isospin breaking effects due to the small mass difference between the up and down quarks using lattice QCD. Our proposal is applicable in princip...

Multi-layer structure in the strongly coupled 5D abelian Higgs model
We explore the phase diagram of the five-dimensional anisotropic Abelian Higgs model by Monte Carlo simulations. In particular, we study the transition between the confining phase and the four-dimensional lay...

The Abelian Higgs model in three dimensions with improved action
We study the Abelian Higgs model using an improved form of the action in the scalar sector. The subleading corrections are carefully analyzed and the connection between lattice and continuous parameters is wo...

Three-dimensional lattice U(1) gauge-Higgs model at low \(m_H\)
We study the non-compact version of the U(1) gauge-Higgs model in three dimensions for \(m_H = 30\) GeV. We found that, using this formulation, rather modest lattices approach ...

Supercompositeness from superstrings
String Unified Models based on the k = 1 level of the Kac-Moody Algebra, predict the existence of “exotic” new states which carry fractional electric charges. We analyse the possibility of considering these “exot...
