[BOOK][B] The black book of quantum chromodynamics: a primer for the LHC era

J Campbell, J Huston, F Krauss - 2018 - library.oapen.org
The LHC (Large Hadron Collider) will serve as the energy frontier for high-energy physics

New -based evaluation of the hadronic contribution to the vacuum polarization piece of the muon anomalous magnetic moment

JA Miranda, P Roig - Physical Review D, 2020 - APS
We revisit the isospin-breaking and electromagnetic corrections to the decay τ-→ π-π 0 ν τ,
which allow its use as input in the two-pion contribution to the (leading-order) hadronic …

form factors in resonance chiral theory and the light-by-light contribution to the muon

P Roig, A Guevara, G López Castro - Physical Review D, 2014 - APS
The description of the VV′ P form factors (V, V′ stands for vector particles and P for a
pseudoscalar meson) for different particles virtualities remains a challenge for the theory of …

Pseudoscalar pole light-by-light contributions to the muon (g− 2) in Resonance Chiral Theory

A bstract We have studied the P→ γ⋆ γ⋆ transition form-factors (P= π 0, η, η′) within a
chiral invariant framework that allows us to relate the three form-factors and evaluate the …

Dispersive representation of the pion vector form factor in τππν τ decays

DG Dumm, P Roig - The European Physical Journal C, 2013 - Springer
We propose a dispersive representation of the charged pion vector form factor that is
consistent with chiral symmetry and fulfills the constraints imposed by analyticity and …
