UKHadron
UKHadron is UKQCD's software package for Lattice QCD. It builds on top of Chroma using it as a library and is meant to provide an easier approach to coding the actual physics.

Projects
B-meson coupling with relativistic heavy quarks
Jonathan Flynn (Investigator), Ben Samways, Dirk Broemmel, Patrick Fritzsch
We non-perturbatively compute the coupling between B* and B pi meson states relying on relativistic heavy quarks and domain wall light fermions. The coupling is of importance for an effective description of hadronic heavy meson decays.
Hadronic structure on the computer
Jonathan Flynn (Investigator), Dirk Broemmel, Thomas Rae, Ben Samways
In experiments at the Large Hadron Collider (LHC) at CERN, Geneva, the interactions that occur between the colliding particles (protons in this case) can be factorised into a simple scattering between two constituent particles, called quarks, followed by a hadronisation process, which describes the dynamics of forming the bound proton states. Quarks are particles within the proton that bind to form composite particles (hadrons) such as a proton. The scattering process can be computed relatively easily, but hadronisation is intrinsically non-perturbative and hard to calculate. Lattice QCD (computer simulation of QCD on a discrete space-time lattice) provides our only known first-principles and systematically-improvable method to address problems like hadronisation. This project uses Iridis to extract parton distribution amplitudes which are experimentally inaccessible, but needed to describe the quark structure of hadrons.
Kaon to two pion decays in lattice QCD
Jonathan Flynn (Investigator), Elaine Goode, Dirk Broemmel
We calculate kaon decay amplitudes on the lattice so we may compare the Standard Model to experiment.
Non-Perturbative Renormalisation on the Lattice
Jonathan Flynn (Investigator), Dirk Broemmel, Thomas Rae
In this project we compute renormalisation factors for various physical observables in a non-perturbative lattice framework. Renormalisation hereby arises due to a fundamental scale dependence of the physical processes.
