Strange Quark Mass Dependence of the Tau Hadronic Width
Joaquim Prades, Antonio Pich
The perturbative quark mass corrections to the tau hadronic width are studied to O(alpha_s^3 m_q^2). Including up to dimension four corrections, we get m_s(4 GeV^2)=(143 \pm 42) Me…
Short- and long-distance contributions to the rare decay K_L-->mu+ mu-
D. Gomez Dumm, A. Pich
The interplay between short- and long-distance contributions to the K_L-->mu+ mu- decay amplitude is analyzed. The long-distance piece is estimated using chiral perturbation theory…
Effective Field Theory
A. Pich
These lectures provide an introduction to the basic ideas and methods of Effective Field Theory, and a description of a few interesting phenomenological applications in particle ph…
Perturbative Quark Mass Corrections to the Tau Hadronic Width
Antonio Pich, Joaquim Prades
The perturbative quark-mass corrections to the hadronic width are analysed to , using the presently available theoretical information. The behaviour of the pert…
Electroweak Precision Physics
A. Pich
Precision measurements of electroweak observables provide stringent tests of the Standard Model structure and an accurate determination of its parameters. A brief overview of the p…
