Parametrisations of the D -> K l nu form factor and the determination of \hat{g}
Sébastien Descotes-Genon, Alain Le Yaouanc
The vector form factor f_+(t) of the semileptonic decay D -> K l nu, measured recently with a high accuracy, can be used to determine the strong coupling constant g_{D_s^* D K}. Th…
The Determination of alpha_s from Tau Decays Revisited
M. Davier, S. Descotes-Genon, A. Hocker +2
We revisit the determination of alpha_s(m_tau) using a fit to inclusive tau hadronic spectral moments in light of (1) the recent calculation of the fourth-order perturbative coeffi…
pi-pi and pi-K scatterings in three-flavour resummed chiral perturbation theory
S. Descotes-Genon
The (light but not-so-light) strange quark may play a special role in the low-energy dynamics of QCD. The presence of strange quark pairs in the sea may have a significant impact o…
How far can you go ? Surprises and pitfalls in three-flavour chiral extrapolations
S. Descotes-Genon
The presence of strange sea quark pairs may have a significant impact of the pattern of chiral symmetry breaking : in particular large differences can occur between the chiral limi…
Low-energy pi-pi and pi-K scatterings revisited in three-flavour resummed chiral perturbation theory
S. Descotes-Genon
Chiral symmetry breaking may exhibit significantly different patterns in two chiral limits: N_f=2 massless flavours (m_u=m_d=0, m_s physical) and N_f=3 massless flavours (m_u=m_d=0…
QCD factorisation and flavour symmetries illustrated in B_d,s -> KK decays
S. Descotes-Genon
We present a new analysis of B_d,s -> KK modes within the SM, relating them in a controlled way through SU(3)-flavour symmetry and QCD-improved factorisation. We propose a set of s…
