Neutrino masses in a conformal multi-Higgs-doublet model
Manuel Fink, Helmut Neufeld
We construct a conformal version of a general multi-Higgs-doublet model with additional right-handed neutrino gauge-singlets. Assuming a minimal extension of the scalar sector by a…
Approximating chiral SU(3) amplitudes
G. Ecker, P. Masjuan, H. Neufeld
We construct large-N_c motivated approximate chiral SU(3) amplitudes of next-to-next-to-leading order. The amplitudes are independent of the renormalization scale. Fitting lattice…
Kaon Decays in the Standard Model
V. Cirigliano, G. Ecker, H. Neufeld +2
A comprehensive overview of kaon decays is presented. The Standard Model predictions are discussed in detail, covering both the underlying short-distance electroweak dynamics and t…
A note on isospin violation in Pl2(gamma) decays
Vincenzo Cirigliano, Helmut Neufeld
We discuss the size of isospin violating effects of both electromagnetic (e \neq 0) and strong (m_u \neq m_d) origin in P_{\ell 2 (γ)} decays. Our results are relevant for the extr…
An evaluation of |Vus| and precise tests of the Standard Model from world data on leptonic and semileptonic kaon decays
M. Antonelli, V. Cirigliano, G. Isidori +9
We present a global analysis of leptonic and semileptonic kaon decay data, including all recent results published by the BNL-E865, KLOE, KTeV, ISTRA+ and NA48 experiments. This ana…
Chiral extrapolation and determination of low-energy constants from lattice data
Gerhard Ecker, Pere Masjuan, Helmut Neufeld
We propose analytic approximations of chiral SU(3) amplitudes for the extrapolation of lattice data to the physical meson masses. The method allows the determination of NNLO low-en…
