Kaon semileptonic decay form factors in two - flavor QCD
نویسنده
چکیده
We present a calculation of the kaon form factors in two-flavor QCD with the non-perturbatively O(a)-improved Wilson quark action. In order to achieve a few percent accuracy in the study of SU(3) breaking effects, we use a set of double ratios of the matrix elements, with which the bulk of the statistical fluctuation and the multiplicative renormalization factors cancel. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

متن کاملLattice QCD Calculations of Nucleon Properties at the Intensity Frontier
During the past decade, lattice QCD has made substantial progress in several areas that influence particle physics, nuclear physics, and astrophysics. Once enough computing and algorithmic power became available to treat virtual quark-antiquark pairs (the “sea” quarks) realistically, the results of lattice-QCD calculations rapidly reproduced a wide variety of hadron properties [1]. The same tec...

The quark-level linear σ model (LσM) is employed to compute a variety of electromagnetic and weak observables of light mesons, including pion and kaon form factors and charge radii, charged-pion polarizabilities, semileptonic weak Kl3 decay, semileptonic weak radiative pion and kaon form factors, radiative decays of vector mesons, and nonleptonic weak K2π decay. The agreement of all these predi...
متن کاملProgress in kaon physics on the lattice
We review recent progress in calculating kaon spectrum, pseudoscalar meson decay constants, B K , ε ¡ £ ¢ ε, K ¤ ππ matrix elements, kaon semileptonic form factors, and moments of kaon distribution amplitudes on the lattice. We also address the issue of how best to improve the staggered fermion formulation for the action and operators.
متن کاملLattice Determination of Semileptonic Form Factors
Computation of the semileptonic form factors for B → π(ρ)lν, B → D(∗)lν and B → K(∗)l+l− decays is a key to the determination of the CKM matrix elements |Vub|, |Vcb| and |Vts| . In this report, I review the recent results by lattice QCD methods. I will mainly focus on the semileptonic decay B → πlν, because lattice calculations in various approaches are already at hand [ 1, 2, 3, 4, 5] and beca...
