Topologically Unquenched QCD: Prospects from an explorative study in 2-flavour-QED(2)
نویسنده
چکیده
The concept of simulating a variant of QCD with sea quarks which interact with the gluon configuration only via global gluonic quantities like ∫ FF̃ dx and ∫ FF dx is tested for the case of the massive 2-flavour Schwinger model. It is found to amount to an importance sampling method which generates –at essentially the costs of a quenched run– an ensemble in between a full and a quenched one, thus providing a competitive alternative to the quenched approximation.

Prospects of ‘Topologically Unquenched QCD’ from a study of the analogous importance sampling method in the massive Schwinger model
I give a quick summary of my proposal for simulating an improvement on quenched QCD with dynamical fermions which interact with the gluon configuration only via the topological index of the latter. It amounts to include only the topological part of the functional determinant into the measure, thereby absorbing a correction factor into the observable. I discuss the prospects of this concept from...
متن کاملFull QED+QCD low-energy constants through reweighting.
The effect of sea quark electromagnetic charge on meson masses is investigated, and first results for full QED+QCD low-energy constants are presented. The electromagnetic charge for sea quarks is incorporated in quenched QED+full QCD lattice simulations by a reweighting method. The reweighting factor, which connects quenched and unquenched QED, is estimated using a stochastic method on 2+1 flav...

We perform an extrapolation from negative to positive flavour numbers of full QCD lattice estimates of the η ′ mass. The extrap-olations are carried out by keeping ρ and π masses at fixed values. We find an η ′ – π splitting which shows a flavour dependence consistent with the Witten Veneziano formula based on the U (1) anomaly. The quantitative splitting is consistent with the estimates made i...
متن کاملProposal for Topologically Unquenched QCD
A proposal is presented for simulating an improvement on quenched QCD with dynamical fermions which interact with the gluon configuration only via the topological index of the latter. Strengths and shortcomings of the method are discussed and it is argued that the approximation – though being crude – shares some qualitative aspects of full QCD which relate to the issue of chiral symmetry breaking.
متن کاملAn estimate of the chiral condensate from unquenched lattice QCD
Using the parameters in the chiral Lagrangian obtained by MILC from their unquenched lattice QCD calculations with 2+1 flavours of sea quarks, I estimate the chiral condensate. I obtain the result 〈ψψ〉(2 GeV)/nf = −(259 ± 27 MeV) in the MS scheme. I compare this value to other determinations.
