Towards precision charm physics with a mixed action
Alessandro Conigli, Julien Frison, Gregorio HerdoÃza +3
We report on our first set of results for charm physics, using a mixed-action setup with maximally twisted valence fermions on CLS ensembles. This setup avoids the need o…
A strategy for B-physics observables in the continuum limit
Alessandro Conigli, Julien Frison, Patrick Fritzsch +7
In a somewhat forgotten paper [1] it was shown how to perform interpolations between relativistic and static computations in order to obtain results for heavy-light observables for…
Heavy semileptonics with a fully relativistic mixed action
Julien Frison, Andrea Bussone, Gregorio HerdoÃza +3
The first phase of a heavy quark program based on twisted mass valence quarks has been presented at last years's lattice conference. The CLS ensembles were used for their…
Systematic errors in partially-quenched QCD plus QED lattice simulations
Antonin Portelli, Stephan Dürr, Zoltán Fodor +9
At the precision reached in current lattice QCD calculations, electromagnetic effects are becoming numerically relevant. Here, electromagnetic effects are included by superimposing…
Determination of the Gradient Flow Scale from a Mixed Action with Wilson Twisted Mass Valence Quarks
Alejandro Saez, Alessandro Conigli, Julien Frison +2
We perform the scale setting procedure of a mixed action setup consisting of valence Wilson twisted mass fermions at maximal twist on CLS ensembles with flavours of $O(a)…
NPR step-scaling across the charm threshold
Julien Frison, Peter Boyle, Nicolas Garron
Matching Non-Perturbative Renormalisation on the lattice and perturbative renormalisation would benefit from higher matching scales, which are needed for observables entering their…
Towards fully bayesian analyses in Lattice QCD
Julien Frison
We present a promising method to learn physical parameters from a bayesian inference, using modern tools to replace both our traditional fits and the way errors are computed and pr…
mass dependence of the topological susceptibility
Julien Frison, Ryuichiro Kitano, Norikazu Yamada
A massless up quark has long been proposed as a solution to the strong CP problem. While this solution is sometimes thought to have been excluded, it is actually still ill-defined.…
Bayesian Inference for Contemporary Lattice Quantum Field Theory
Julien Frison
Bayesian inference provides a rigorous framework to encapsulate our knowledge and uncertainty regarding various physical quantities in a well-defined and self-contained manner. Uti…
Hadronic physics from a Wilson fermion mixed-action approach: Setup and scale setting
Andrea Bussone, Alessandro Conigli, Julien Frison +6
We introduce a lattice QCD mixed action approach that employs Wilson-type quarks in the sea and valence sectors. The sea sector is based on gauge ensembles with fla…
Large-Scale AI in Telecom: Charting the Roadmap for Innovation, Scalability, and Enhanced Digital Experiences
Adnan Shahid, Adrian Kliks, Ahmed Al-Tahmeesschi +132
This white paper discusses the role of large-scale AI in the telecommunications industry, with a specific focus on the potential of generative AI to revolutionize network functions…
and in flavour QCD from a combination of continuum limit static and relativistic results
Alessandro Conigli, Julien Frison, Patrick Fritzsch +7
We present preliminary results for B-physics from a combination of non-perturbative results in the static limit with relativistic computations satisfying …
in iso-symmetric QCD and the CKM matrix unitarity
Alessandro Conigli, Julien Frison, Alejandro Sáez
We present lattice results for in the iso-symmetric limit of pure QCD (isoQCD) with flavours, along with a determination of and a study on…
The Kaon Bag Parameter at Physical Mass
Julien Frison, Peter Boyle, Norman H. Christ +4
We present preliminary results for the calculation of the Kaon Bag parameter in lattice QCD, using Möbius Domain Wall Fermion ensembles generated by the RBC-UKQCD…
Hadronic physics from a Wilson fermion mixed-action approach: Charm quark mass and meson decay constants
Andrea Bussone, Alessandro Conigli, Julien Frison +5
We present our first set of results for charm physics, using the mixed-action setup introduced in a companion paper. Maximally twisted Wilson valence fermions are used on a sea of…
Topological susceptibility with a single light quark flavour
Julien Frison, Ryuichiro Kitano, Norikazu Yamada
One of the historical suggestions to tackle the strong CP problem is to take the up quark mass to zero while keeping finite. The angle is then supposed to become irrelev…
renormalisation of four-quark operators
Julien Frison, Peter Boyle, Nicolas Garron
When several four-quark operators are allowed to mix through renormalisation, this can considerably amplify the problems coming from perturbative truncation and discretisation effe…
Charmed semileptonics with twisted-mass valence quarks
Julien Frison, Gregorio Herdoiza, Carlos Pena +2
Our charm program uses a mixed action with twisted-mass valence quarks over non-perturbatively improved Wilson sea quarks, in order to study various quantities in a relativistic an…
