The B -> Xs gamma Rate and CP Asymmetry within the Aligned Two-Higgs-Doublet Model
Martin Jung, Antonio Pich, Paula Tuzón
In the two-Higgs-doublet model the alignment of the Yukawa matrices in flavour space guarantees the absence of flavour-changing neutral currents at tree level, while introducing ne…
The vector form factor at the next-to-leading order in 1/N(C): chiral couplings L9(mu) and C88(mu) - C90(mu)
Antonio Pich, Ignasi Rosell, Juan Jose Sanz-Cillero
Using the Resonance Chiral Theory Lagrangian, we perform a calculation of the vector form factor of the pion at the next-to-leading order (NLO) in the 1/N(C) expansion. Imposing th…
Flavour constraints on multi-Higgs-doublet models: Yukawa alignment
Antonio Pich
In multi-Higgs-doublet models, the alignment in flavour space of all Yukawa matrices coupling to a given right-handed fermion guarantees the absence of tree-level flavour-changing…
Duality violation in QCD Sum Rules with the LR correlator
Martín González-Alonso, Antonio Pich, Joaquim Prades
We analyse the so-called violations of quark-hadron duality in Finite Energy Sum Rules with the LR correlator, through the study of the possible high-energy behavior of the LR spec…
Charged-Higgs phenomenology in the Aligned two-Higgs-doublet model
Martin Jung, Antonio Pich, Paula Tuzón
The alignment in flavour space of the Yukawa matrices of a general two-Higgs-doublet model results in the absence of tree-level flavour-changing neutral currents. In addition to th…
Pinched weights and Duality Violation in QCD Sum Rules: a critical analysis
Martin Gonzalez-Alonso, Antonio Pich, Joaquim Prades
We analyze the so-called pinched weights, that are generally thought to reduce the violation of quark-hadron duality in Finite-Energy Sum Rules. After showing how this is not true…
The Aligned two-Higgs Doublet model
Antonio Pich, Paula Tuzon
In the two-Higgs-Doublet model the alignment of the Yukawa flavour matrices of the two scalar doublets guarantees the absence of tree-level flavour-changing neutral couplings. The…
Alpha_s Determination from Tau Decays: Theoretical Status
Antonio Pich
The total tau hadronic width can be accurately calculated using analyticity and the operator product expansion. The result turns out to be very sensitive to the value of alpha_s(m_…
Violation of Quark-Hadron Duality and Spectral Chiral Moments in QCD
Martin Gonzalez-Alonso, Antonio Pich, Joaquim Prades
We analyze the spectral moments of the V-A two-point correlation function. Using all known short-distance constraints and the most recent experimental data from tau decays, we dete…
