A dispersive method to study CP asymmetries in hadronic multi-body decays
L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +5
We present the details of a dispersive method to construct the amplitudes for hadronic multibody decays based on the universality of pairwise hadronic final-state interactions…
Extending the Kinetic Mass to Higher Orders in
Thomas Mannel, Ilija S. Milutin, Rens Verkade +1
Currently, the kinetic mass is defined in terms of the pole mass and operators at order , which are known to NLO accuracy in . At the same time, the Heavy Quark E…
Understanding large localized CP violation in using dispersive methods
L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +4
We utilize the universality of pion-pion () final-state interactions at small invariant masses to understand the enhanced localized CP violation in , usin…
Goldstone Bosons in Effective Theories with Spontaneously Broken Flavour Symmetry
Michaela E. Albrecht, Thorsten Feldmann, Thomas Mannel
The Flavour Symmetry of the Standard Model (SM) gauge sector is broken by the fermion Yukawa couplings. Promoting the Yukawa matrices to scalar spurion fields, one can break the fl…
Role of "Intrinsic Charm" in Semi-Leptonic B-Meson Decays
C. Breidenbach, T. Feldmann, T. Mannel +1
We discuss the role of so-called "intrinsic-charm" operators in semi-leptonic B-meson decays, which appear first at order 1/m_b^3 in the heavy quark expansion. We show by explicit…
Model-independent Analysis of Lepton Flavour Violating Tau Decays
B. M. Dassinger, Th. Feldmann, Th. Mannel +1
Many models for physics beyond the Standard Model predict lepton-flavour violating decays of charged leptons at a level which may become observable very soon. In the present paper…
