Non-perturbative renormalisation of Delta F=2 four-fermion operators in two-flavour QCD
P. Dimopoulos, G. Herdoiza, F. Palombi +4
Using Schroedinger Functional methods, we compute the non-perturbative renormalisation and renormalisation group running of several four-fermion operators, in the framework of latt…
Relativistic corrections to the static potential at O(1/m) and O(1/m^2)
Yoshiaki Koma, Miho Koma, Hartmut Wittig
We investigate the relativistic corrections to the static potential, i.e. the O(1/m) potential and the O(1/m^2) velocity-dependent potentials, in SU(3) lattice gauge theory. They a…
Weak low-energy couplings from topological zero-mode wavefunctions
P. Hernandez, M. Laine, C. Pena +3
We discuss a new method to determine the low-energy couplings of the weak Hamiltonian in the -regime. It relies on a matching of the topological poles in of three…
Nonperturbative determination of the QCD potential at O(1/m)
Yoshiaki Koma, Miho Koma, Hartmut Wittig
The relativistic correction to the QCD static inter-quark potential at O(1/m) is investigated nonperturbatively for the first time by using lattice Monte Carlo QCD simulations. The…
A strategy for implementing non-perturbative renormalisation of heavy-light four-quark operators in the static approximation
F. Palombi, M. Papinutto, C. Pena +1
We discuss the renormalisation properties of the complete set of four-quark operators with the heavy quark treated in the static approximation. We elucidate the role of he…
Determination of the spin-dependent potentials with the multi-level algorithm
Miho Koma, Yoshiaki Koma, Hartmut Wittig
The spin-dependent corrections to the static interquark potential are relevant to describing the fine and hyper-fine splittings of the heavy quarkonium spectra. We investigate thes…
