Weak and Higgs physics from the lattice
Sofie Martins, Patrick Jenny, Axel Maas +1
The manifestly gauge-invariant and non-perturbatively complete lattice formulation of the weak interactions and the Brout-Englert-Higgs effect is connected to the usual perturbativ…
High-Performance Simulations of Higher Representations of Wilson Fermions
Vincent Drach, Sofie Martins, Claudio Pica +1
We present HiRep v2, an open-source software suite for high-performance lattice field theory simulations with dynamical Wilson fermions in higher representations of gauge…
The singlet scalar state in a chiral ensemble in with two fundamental flavours
Laurence Sebastian Bowes, Vincent Drach, Patrick Fritzsch +3
Composite Higgs models are a class of Beyond the Standard Model (BSM) models proposed to address the hierarchy and naturalness problems associated with the Standard Model (SM) Higg…
Determination of the pseudoscalar decay constant from SU(2) with two fundamental flavors
Laurence Sebastian Bowes, Vincent Drach, Patrick Fritzsch +3
The SU(2) gauge group with two fundamental flavors is a candidate for a composite Higgs extension of the Standard Model. Central to Higgs phenomenology is a non-perturbative determ…
Scaling SU(2) to 1000 GPUs using HiRep
Sofie Martins, Erik Kjellgren, Emiliano Molinaro +2
HiRep allows flexible simulations of higher representations of Wilson Fermions with various actions and gauge groups and a range of inverters and integrators. This is particularly…
Exponential Error Reduction for Glueball Calculations Using a Two-Level Algorithm in Pure Gauge Theory
Lorenzo Barca, Francesco Knechtli, Sofie Martins +3
This study explores the application of a two-level algorithm to enhance the signal-to-noise ratio of glueball calculations in four-dimensional pure gauge theory. O…
GPU-accelerated Higher Representations of Wilson Fermions with HiRep
Sofie Martins, Erik Kjellgren, Emiliano Molinaro +2
We are improving one of the available lattice software packages HiRep by adding GPU acceleration supporting highly-optimized simulations on both NVIDIA and AMD GPUs. HiRep allows l…
LDIC Survey 2023: Feeling Welcome in the Community
Christopher Aubin, Bipasha Chakraborty, Will Detmold +4
We review the level of welcomeness that members of the lattice field theory community feel based on the results of a survey performed in May and June 2023. While respondents report…
