Title: | Kaon physics from lattice QCD | Authors: | Lubicz, Vittorio | Keywords: | Lattice QCD Kaon physics |
Issue Date: | 2009 | Publisher: | PoS - Proceedings of Science | Pages: | 013 | Abstract: | I review lattice calculations and results for hadronic parameters relevant for kaon physics, in particular the vector form factor f+(0) of semileptonic kaon decays, the ratio fK/fp of leptonic decay constants and the kaon bag parameter BK. For each lattice calculation a colour code rating is assigned, by following a procedure which is being proposed by the Flavianet Lattice Averaging Group (FLAG), and the following final averages are obtained: f+(0) = 0.962(3)(4), fK/ fp =1.196(1)(10) and BK = 0.731(7)(35). In the last part of the talk, the present status of lattice studies of non-leptonic K -> pipi decays is also briefly summarized. | URI: | http://hdl.handle.net/2307/298 |
