Tau Physics: Theoretical Perspective
A. Pich
The leptonic decays of the tau lepton provide relevant tests on the structure of the weak currents and the universality of their couplings to the gauge bosons. The hadronic tau dec…
Theoretical status of epsilon'/epsilon
A. Pich
The Standard Model prediction for epsilon'/epsilon is updated, taking into account the most recent theoretical developments. The final numerical value, epsilon'/ε= (17\pm 6) x 10^{…
The Standard Model prediction for eps'/eps
E. Pallante, A. Pich, I. Scimemi
We review fundamental aspects of a new Standard Model analysis of eps'/eps which takes into account the strong enhancement induced by final state interactions.
Final State Interactions in Kaon Decays
Elisabetta Pallante, Antonio Pich
We quantify the important effect of strong final state interactions in the weak amplitudes, using the measured - phase shifts with J=0 and . The main results…
S-wave Kpi scattering in chiral perturbation theory with resonances
Matthias Jamin, Jose Antonio Oller, Antonio Pich
We present a detailed analysis of S-wave Kpi scattering up to 2 GeV, making use of the resonance chiral Lagrangian predictions together with a suitable unitarisation method. Our ap…
Electromagnetism in nonleptonic weak interactions
G. Ecker, G. Isidori, G. Mueller +2
We construct a low-energy effective field theory that permits the complete treatment of isospin-breaking effects in nonleptonic weak interactions to next-to-leading order. To this…
The hadronic off-shell width of meson resonances
D. Gomez Dumm, A. Pich, J. Portoles
Within the resonance chiral effective theory we study the dressed propagators of the spin-1 fields, as arise from a Dyson-Schwinger resummation perturbatively constructed from loop…
Aspects of Quantum Chromodynamics
A. Pich
These lectures provide an overview of Quantum Chromodynamics (QCD), the SU(3) gauge theory of the strong interactions. The running of the strong coupling and the associated propert…
