Determining the strong coupling: status and challenges
Antonio Pich, Juan Rojo, Rainer Sommer +1
The `XIIIth Quark Confinement and the Hadron Spectrum' conference (Confinement 2018) contained a `Round Table Discussion' on the status of the determinations of the strong coupling…
Heavy resonances and the electroweak effective theory
Ignasi Rosell, Claudius Krause, Antonio Pich +2
Taking into account the negative results of direct searches for beyond the Standard Model fields and the consequent mass gap between Standard Model and possible unknown states, the…
Tau-decay determination of the strong coupling
Antonio Pich
We review the current status of the determination of the strong coupling from tau decay. Using the most recent release of the ALEPH data, a very comprehensive phenomenological anal…
Confronting hadronic tau decays with non-leptonic kaon decays
Antonio Rodríguez Sánchez, Antonio Pich
In the chiral limit, the contribution to the Operator Product Expansion (OPE) of the correlator of quark currents only depends on two vacuum condensates, whi…
Updated Standard Model Prediction for
Hector Gisbert, Antonio Pich
A recent lattice evaluation of , finding a 2.1 deviation from the experimental value, has revived the old debate about a possible $\varepsilon'/\varep…
Colorful Imprints of Heavy States in the Electroweak Effective Theory
Claudius Krause, Antonio Pich, Ignasi Rosell +2
We analyze heavy states from generic ultraviolet completions of the Standard Model in a model-independent way and investigate their implications on the low-energy couplings of the…
Flavour Dynamics and Violations of the CP Symmetry
Antonio Pich
An overview of flavour physics and CP-violating phenomena is presented. The Standard Model quark-mixing mechanism is discussed in detail and its many successful experimental tests…
Effective Field Theory with Nambu-Goldstone Modes
Antonio Pich
These lectures provide an introduction to the low-energy dynamics of Nambu-Goldstone fields, associated with some spontaneous (or dynamical) symmetry breaking, using the powerful m…
