چکیده
which governs a classical motion in the space of link variables. φ is the pseudofermion field, whereas P is the canonical momenta, which is randomized at the beginning of each trajectory. For the classical motion we need the gauge derivative of pseudofermionic action, namely the fermion force. For the fermion force one needs to invert the overlap operator on the φ field: force = −ψ dDD dU ψ, where ψ = (DD)φ,

We report calculations of B K using two flavours of dynamical clover-improved Wilson lattice fermions and look for dependence on the dynamical quark mass at fixed lattice spacing. We see some evidence for dynamical quark effects. In particular B K decreases as the sea quark masses are reduced towards the up/down quark mass. Our meson masses are quite heavy and a firm prediction of B K is a task...

The Hybrid Monte Carlo (HMC) algorithm[1] is now the standard method to simulate dynamical fermions. However the cost of the algorithm is substantial. It is therefore desirable to improve the efficiency of the HMC algorithm. First, we examine the possibility of changing the step size adaptively[2,3]. Second, we implement the HMC algorithm with approximate Hamiltonians. Lastly, we precondition t...

We discuss a simulation algorithm for dynamical fermions, which combines the multiboson technique with the Hybrid Monte Carlo algorithm. The algorithm turns out to give a substantial gain over standard methods in practical simulations and to be suitable for dealing with fermion zero modes in a clean and controllable way.
